Právě vznikla tištěná turistická mapa Prahy, na základě aktuálních dat OpenStreetMap. Je určená lidem, kteří do Prahy přijeli na pár dnů a chtějí se rychle zorientovat v tom nejzajímavějším, co Praha nabízí.

Mapový podklad je záměrně jednoduchý. Obsahuje síť ulic a jen nezbytné množství dalších informací. Díky tomu zůstává přehledný a dává prostor tomu dalšímu. Přibližně stovce zajímavých míst, která jsou na mapě vyznačena pomocí malých ilustrací a popisků. Vedle známých historických památek jsou tu i ty méně známé, moderní stavby, veřejné umění nebo technické zajímavosti.

Asi vás napadne, proč ještě dnes tisknout mapu, když máme telefony i encyklopedie v kapse. Odpověď je jednoduchá. Nejde o náhradu digitálních map. Ty používáme všichni. Papírová mapa jen nabízí jiný pohled na totéž.

Rozložená ukazuje celé historické město najednou. Vidím vzdálenosti mezi místy, představím si kudy se vydám na první pohled - a nechám oči chvíli bloudit po ulicích. Je to trochu pomalejší způsob, jak se zorientovat. A právě v tom je kouzlo map, na které už tak trochu zapomínáme. Na ostrém slunci zůstává čitelná, nepotřebuje baterii a můžete si do ní poznačit tužkou místo, které vás zaujalo. Po návratu domů se mapa promění ve vzpomínku na navštívená místa. Na zadní straně jsou stručné informace o nejvýznamnějších pražských památkách v devíti světových jazycích. Je to základní přehled bez nutnosti je hledat.

Trochu se chlubím. Graficky jsem ji připravil, vyzkoušel si, jak na každém milimetru, na každém odstínu záleží. Vydali jsme ji ve vydavatelství, v kterém se turistickým publikacím už nějakou dobu věnujeme. Je tu vidět síla čerstvých mapových dat, za nimiž stojí komunita a tak trochu i moje celoživotní znalost rodného města. Míst je hodně, ale vybrat z nich nějakou sbírku vzpomínek které mám trvale zapsány, na to už databázový dotaz nestačí. Chtěl jsem ukázat Prahu jako rozmanité a přitom ne zas tak veliké město. Nejen jako ukazovač tras od startu do cíle.

Pokud vám během návštěvy Prahy mapka pomůže jen jednou, splnila účel. A možná se tak připomene, že pomalý analogový svět ještě neřekl poslední slovo. S pomocí nových zkušeností je později můžeme propojit s budoucností.

A new printed tourist map of Prague has just been published, built directly on up-to-date OpenStreetMap data. It is designed for visitors who arrive in the capital of the Czech Republic for a few days and want a quick, clear orientation to the very best the city has to offer.

In static cartography, the base map is intentionally kept minimal. It features the street network alongside only the essential geographic elements. This clean background leaves ample room for what matters most: roughly one hundred curated points of interest, brought to life with small custom illustrations and brief labels. Beside iconic historical landmarks, the map highlights lesser-known sights, modern architecture, public art, and unique engineering points of interest.

You might wonder why anyone would print a physical map today, when we all carry navigation apps and encyclopedias in our pockets. The answer is simple: it isn’t meant to replace digital tools. We all use those daily. A paper map simply offers a different perspective on the same space.

Unfolded, it presents the entire historic city at a single glance. You can feel the true distances between places, plot out a walk visually, or simply let your eyes wander across the streets. It invites a slightly slower pace of orientation—a classic form of spatial magic we sometimes forget in the digital age. It stays perfectly legible in bright sunlight, requires no battery, and lets you mark your favorite spots with a pencil. Long after you return home, it turns into a tangible keepsake of your journey. On the back, concise overviews of Prague’s major sights are provided in nine languages, offering quick context without needing to search online.

To be a bit personal: I had the privilege of working on the graphic design and cartographic preparation for this project, testing firsthand how much every single millimeter and color nuance matters in print. It was published by our team, where we’ve been crafting travel publications for years. The finished map really showcases the strength of fresh, community-driven OSM data combined with a lifetime of personal knowledge of my hometown.

While database queries can easily return thousands of locations, filtering them down to a meaningful collection of memories requires a human touch. I wanted to show Prague as a rich, diverse, yet walkable city—not just calculate the fastest route from point A to point B.

If this map helps you navigate or discover something new during your visit, even just once, it has fulfilled its purpose. And perhaps it serves as a gentle reminder that the slow, tactile world still has plenty to offer—especially when powered by open data and brought forward into the future.

After integrating OpenStreetMap data into my own application, I noticed inaccurate or missing business information, so I started correcting it directly on OSM.

We had an awesome, hop-py time with the UPRI YouthMappers! The other day, I had an opportunity to facilitate a mobile-first workshop where we got hands-on with Vespucci, swapped mapping tips, and learned to read topographic maps for clues about where watercourses might be. We also tackled tagging questions and talked about ways to join our #ChasingWaterways campaign.

Icebreaker participants launching themselves forward. Can you guess how this exercise is relevant to our theme?

Kudos to our hosts

A big thank-you to Feye and the lovely UPRI OSM mapping team—Erika, Raf, Steph, and Ureil—for hosting and organizing the day. I’m glad to finally tie faces to familiar, waterway-chasing usernames. It was also great to meet both current YouthMappers and a bunch of hopeful new applicants.

Everyone already knew their way around iD/Rapid, and the more experienced mappers were using JOSM, so we skipped the beginner stuff and dipped our toes into Vespucci. sometime ### Mapping from your pocket

Vespucci was a great fit for the day: it’s made just for Android, but gives mappers an option for editing on the go, and has powerful tools for more complex tasks. It can also handle MapRoulette tasks, though a recent security incident temporarily took the MapRoulette API offline. That meant awkwardly switching apps, which could get tedious when you’re on a roll.

We spent the morning exploring the app basics – plus some of the more advanced features, answering questions, and sharing ways to use of other resources alongside aerial imagery to spot waterways and check flow directions.

One of the tools we had fun with was visualizing waterways with #WaterwayMapOrg, and how all rivers flow to the sea. Or not.

Some questions—like whether Vespucci can “square” buildings or draw round shapes—also got us talking about the little editor features we all get attached to.

After a hearty lunch, it was time for a mini mapa-thon! We worked on #TulayTuloy, a beginner-friendly bridge-mapping project and a fun side quest to our bigger waterway campaign. Bridges are important structures—and useful landmarks right over the water.

How far can you jump?

We were curious about the familiar OSM rule of thumb that a stream is something an active, able-bodied person can jump across. Our project guidelines use 2 meters as the cutoff, so we put it to the test.

Most jumps landed around 1.3 meters, and the longest was 1.8 meters. No one cleared 2 meters—and there were a few laughs when people realized just how wide that is!

Afterwards, I heard somebody made a pun #TalonTalon, after the #TulayTuloy hashtag.

My favorite part of the day was exploring DEMs, contour lines and hill shading. Topographic maps can be especially useful when imagery is cloudy or unavailable, and participants were amazed that they can spot features they’d missed before once they knew what and where to look.

After all that hopping, we dove into waterway mapping, where we discovered the limitations of using small screens, explored and tried workarounds, and still managed to complete tasks, giving everyone a chance to polish their new Vespucci editing skills.

Want to try to map a waterway near you? Find a #ChasingWaterways task and give it a try!

Hop-py folks, happily posing for a group-fie.

We’ve already penciled a date for another mapa-thon next month, and we’d be very happy to see you join us, whether you map with Vespucci, or the more usual suspects: iD/RapiD or JOSM.

We’ll post a message as soon as we nail down the details. Watch for announcements in the local communities’ channels.

P.S. I’m pleased to share that many of the issues we faced with the Maproulette mobile interface has been addressed in the upcoming version 4, hopefully, that means we’d have a smoother workflow for Vespucci users in the next mapa-thon.

Ludell is a small township in Rawlins County, Kansas. I’ve mapped every building, road, the stream that goes through it.

If you hike, ski, or drive in North America, your OsmAnd terrain may already be much sharper than you think. Since spring 2026, terrain maps and contour lines for the United States (including Alaska), Canada, and Mexico are built from high-resolution national elevation data. If you have not updated these maps since then, you are still looking at the old, smoother relief.

What Changed​

The new maps use elevation data with about 10 m resolution in the mainland United States and about 30 m in Alaska and most of Canada and Mexico. In practice, that means smaller ridges, narrower gorges, and steeper cliffs show up where the map used to smooth them out.

The update covers two map types:

• Terrain maps (3D) — the base for 3D relief, Hillshade, and Slope layers.
• Contour lines — regenerated from the same new data, so they match the relief exactly.

More detail takes a bit more space: updated maps are up to one and a half times larger than before.

Data: USGS 3D Elevation Program (via The National Map and OpenTopography), including data from Natural Resources Canada (NRCan) and INEGI (Mexico).

Updated Regions​

• United States, including Alaska
• Most of Canada and Mexico

See It in the Grand Canyon​

Few places test a terrain map like the Grand Canyon. Seen from above, the side canyons branch out in fine detail, and the contour lines follow every bend of the walls down to the Colorado River.

Tilt the map into 3D, and the canyon rises off the screen: Plateau Point, Skeleton Point, and the trail down to Phantom Ranch sit right where the terrain says they should.

Works Offline​

Terrain maps are stored on your device, just like the rest of your OsmAnd maps. Once downloaded, the relief, contour lines, and 3D view keep working without an internet connection, which is handy at the bottom of a canyon, where signal is rarely part of the scenery.

How to Get the Update​

Terrain maps downloaded before May 2026 still contain the old data. Open the Updates tab in Maps & Resources: if terrain or contour line maps for these regions are listed, update them. There is no need to delete the old files first. If you do not have them yet, download the Terrain map (3D) and Contour lines for the regions you need. Terrain and contour line maps require OsmAnd Maps+ or Pro; 3D relief requires OsmAnd Pro.

Every night across southern Iraq, hundreds of gas flares burn over some of the largest oil fields on earth. They torch associated gas that could light millions of homes — in a country where those same homes get a few hours of grid power a day and the rest from diesel generators. The gas is burned because capturing it was never built. The flames are visible from space, yet on the ground almost no one is counting them.

So I built Iraq Flaring Watch to count them in public — a live map of Iraq’s flaring, what it’s wasting, and who it’s affecting. This diary is about how it came together, and why OpenStreetMap ended up at the centre of it.

What it is

Iraq Flaring Watch is a single-page map that pulls open scientific data together in one place:

OpenStreetMap

the flare locations themselves — every flare on the map is an OSM man_made=flare node, so what you see is what mappers have put on OSM. There are two modes: a preloaded layer (a saved Overpass snapshot committed to the repo) that keeps load off Overpass and gives me a stable baseline to spot vandalism against, and a Live OSM option that pulls the current data straight from Overpass in real time.

NASA FIRMS (VIIRS)

near-real-time satellite fire detections, so you see what the satellites saw in the last few days, not a static snapshot.

Carbon Mapper

satellite methane and CO₂ plume detections (Tanager), showing which flares are leaking as well as burning.

World Bank

global flaring data, for the volumes and the national baseline.

WorldPop

the population raster, intersected with flare buffers to estimate the people living within 5 km of a flare.

Leaflet.js

the open-source engine that draws it all, with no proprietary basemap and no API gatekeeper.

Not one of those sent me an invoice. A single person, working evenings, can take open satellite data, open demographic rasters and open economic datasets, put them on an open map, and hold an oil industry’s waste up to daylight. That’s the part that still amazes me.

Where OSM comes in

Building the map made me confront how blank Iraq’s industrial layer is on OSM. Some of the largest oil fields on earth sit in the south, and large stretches of them are, on the map, empty desert. Gas-processing plants, flare stacks, oil gathering stations, storage depots — huge, permanent installations — simply aren’t there.

Iraq Flaring Watch turned out to be the perfect fix for that, because a persistent flare is a facility announcing its own coordinates every night. So the project became a mapping engine as much as a monitoring one:

1. A flare shows up as a persistent hotspot over a spot OSM thinks is bare.
2. I cross-check it against what’s already mapped. OpenInfraMap is my first lens — it renders OSM’s power and oil/gas layer beautifully, so I can see at a glance whether anything near the flare already exists. Overpass Turbo is the audit next to it, querying the area to see exactly what’s tagged and how.
3. I open the spot in satellite imagery, find the facility that’s obviously there, and trace it into OSM — or fix what’s already there and mistagged.

The flaring data and OSM correct each other: the fires point me at infrastructure to map, and the infrastructure I map turns an anonymous heat signature into a named, located, correctly-tagged thing anyone can use.

You can see the effect in OSM’s own history. The number of flares tagged man_made=flare in Iraq sat in the low tens for years; through the Iraq Flaring Watch work it has climbed to 438 today, and most of that recent jump is flares I traced after a satellite detection pointed me at them.

Open all the way through

I could have kept this private. But a flaring map built on a proprietary basemap and a closed dataset is a dead end — nobody can check it, nobody can extend it, and the day I stop maintaining it, it’s gone. So the project is open at every layer:

• The data in is open — OSM (the flare locations themselves, via Overpass), NASA FIRMS, Carbon Mapper, World Bank and WorldPop.
• The infrastructure I discover goes into OSM, the one layer I contribute back to and the one that outlives the project. A gas-processing plant or gathering station I add because of a flare detection is there for a transport mapper, a humanitarian team, an air-quality study, an OpenInfraMap user — whoever needs it next.
• The code out is open too. Iraq Flaring Watch is on GitHub under the MIT licence at github.com/rawazrauf/iraq-flaring-watch. The map itself is a serverless index.html — no backend; it reads OSM flares either from a preloaded Overpass snapshot or live from Overpass — but behind it sits a small pipeline of open queries I wrote to turn raw data into the figures on the map. A Google Colab script buffers every flare by 5 km, clips the WorldPop raster and sums the population to get who lives nearby; another script pages the Carbon Mapper API for Tanager methane and CO₂ plume detections over Iraq; a notebook matches NASA VIIRS fire detections to individual flares; and the World Bank GGFR volumes feed the national economics. Every query, and every JSON output it produces, is committed to the repo, so the whole chain from open data to published number is auditable and reproducible — not a black box.
• There’s nothing Iraq-specific about the machinery. Swap the bounding box and the national figures and the same stack becomes Flaring Watch for Nigeria, Libya, Algeria, Turkmenistan — anywhere gas is burning and nobody’s counting. If you want to stand one up for your country, please do; that’s what the licence is for.

How you can help

Iraq’s energy infrastructure is one of the most under-mapped layers anywhere, and there’s a clear, high-impact order to work in. If you map in Iraq — or want to — here’s where to start:

1. Add man_made=flare for flares that aren’t mapped yet. Iraq Flaring Watch shows you exactly where they’re burning; cross-check against satellite imagery and OpenInfraMap, then tag the flare stacks that are still missing. This is the single most useful thing, and the chart above is literally the scoreboard.
2. Add industrial=wellsite polygons around existing man_made=petroleum_well points. Iraq has over 3,000 oil wells mapped as points, but only around 1,000 have their wellsite drawn as a polygon (you can see the gap on OpenInfraMap). Tracing the wellsite footprint around a well point turns a dot into a real, measurable facility.
3. Add the rest of the missing oil, electricity and water infrastructure. Open OpenInfraMap over Iraq and fill in what’s absent — refineries, gas-processing plants and pipelines on the oil-and-gas side; power plants, substations and transmission lines on the electrical side; treatment and pumping stations on the water side. For the oil and gas facilities, the flare data is a free, precise guide to where to look.

Take a look

The site is live at iraqflaringwatch.com, and the source is on GitHub under the MIT licence at github.com/rawazrauf/iraq-flaring-watch — fork it, adapt it, and point it at your own country.

The fires are easy to see from space. Getting them onto the map is the part that needs mappers.

KonGeoS - Konferenz der Geodäsie-Studierenden

Die KonGeoS ist die Konferenz der Geodäsie-Studierenden der Hochschulen im DACH-Raum und findet zweimal jährlich statt. Ziel ist es die Studierenden der 24 Geodäsie-Fachschaften aus Deutschland, Österreich und der Schweiz in einem fachlichen und auch persönlichen Austausch miteinander zu vernetzen. Die mehrtägige Veranstaltung ermöglicht aktuelle Themen aus Studium und Beruf zu diskutieren, Fachvorträge zu hören, Erfahrungen zwischen Hochschulen auszutauschen, in Arbeitsgruppen an Themen zu arbeiten sowie das Exkursionsangebot zu Unternehmen, Behörden und Forschungseinrichtungen zu nutzen, um Kontakte zu potenziellen Arbeitgebern und Berufsverbänden zu knüpfen. Das Programm ist auf der Webseite zusammengefaßt. Die KonGeoS tourt, ähnlich wie die FOSSGIS-Konferenz, durch den DACH-Raum. Vom 15. bis 17. Oktober 2026 fand die KonGeoS an der Hochschule Mainz statt.

Beim Ausstellerforum am Freitagnachmittag informierten FOSSGIS-Mitglieder über Open-Source-GIS und OpenStreetMap und den FOSSGIS-Verein. Zahlreiche Studierende kennen schon QGIS oder OpenStreetMap, hatten jedoch noch keine Berührungspunkte mit FOSSGIS e.V., das Interesse an der FOSSGIS-Konferenz war hoch sowie auch die Sticker auf großes Interesse stießen.

Danke an Anja Eisert (Konferenzorgateam, Team Vernetzungstreffen), Robin Durner (OpenTransportCommunity, OSM), Kai-Christian Bruhn (Hochschule Mainz) und Thomas Bentler (BKG) für den Einsatz am FOSSGIS-Infostand.

FOSSGIS-OSM-Communitytreffen Nr. 26

OpenStreetMap und FOSSGIS sind das Zugangstor zu nachhaltiger Geoinformation. Um noch mehr Menschen davon zu begeistern, trafen sich
vom 02.-04. Oktober 2026 wieder 25 Aktive aus der deutschsprachigen OpenStreetMap- und FOSSGIS-Community zum FOSSGIS-OSM-Communitytreffen im Linuxhotel in Essen. Diesmal erwies sich die Mobilität der Deutschen Bahn als besonders nachhaltig, indem sie die Ankunft einiger Teilnehmenden nach erlebnisreichen Rundreisen besonders weit in die Zukunft verlegte. So erreichten die letzten Teilnehmerinnen das Treffen gegen Ende der Geisterstunde. Nichtsdestotrotz (oder gerade deshalb) wurde auch dieses Treffen wieder ein voller Erfolg!

Das Besondere an diesen Treffen, welches eine Mischung aus Hackathon, Vereinsarbeit, Netzwerktreffen und Ideenwerkstatt ist, war der erfreulich hohe Anteil von Teilnehmerinnen. Einige waren zum ersten Mal dabei, wie Nora, die ihre persönlichen Eindrücke im Wiki beschrieben hat. Fränze Kellig hat mit ihrem Besuch beim Arbeitstreffen ihren Dienst angetreten und das Wochenende genutzt, um sich zu informieren und die Einarbeitung zu starten. Wir freuen uns, dass wir Euch, wie die anderen neuen Teilnehmerinnen, für den FOSSGIS und OpenStreetMap begeistern konnten!

Vereinsarbeit

Die AG Öffentlichkeitsarbeit dess FOSSGIS e.V. traf sich zu einer Session, in der verschiedene anstehende Aufgaben beleuchtet und besprochen wurden.
So ging es um die Ausgestaltung und Umsetzung des CartoHack - ein Format, welches zusammen mit der DGfK weitergeführt wird, indem regelmäßig in einer Onlinesession etwas Kartographisches demonstriert wird.
Die Smart Country Convention stand unmittelbar bevor. Torsten Friebe hatte mit seinem Unternehmen lat/lon einen Stand im OpenSource Park der OSBA gebucht und wollte bei dieser Gelegenheit den FOSSGIS e.V. bewerben und um eine Präsentation gebeten. Die zu präsentierenden Inhalte wurden besprochen. Die Unterstützung für OSM-Stammtische/ in Form von Werbung über Mastodon und Vorlagen für eigne Werbung wurden besprochen sowie dass eine Anleitung zur Organisation solcher Treffen aufgeschrieben werden möchte. Weitere Themen waren die Optimierung der Social Media Interaktion des FOSSGIS e.V und seiner Community sowie die Diskussion um die Idee des OSM-Maskottchens.

Unterstützend für die Einarbeitung von Fränze war die Session “FOSSGIS e.V. visualisieren” sowie eine Diskussionsrunde um die Werte, die wir mit dem FOSSGIS e.V verbinden, welche von Katja angestoßen wurde.

Die AG Öffentliche Ausschreibung mit FOSS besprach Ideen zum Thema des Panelgesprächs auf der nächsten FOSSGIS-Konferenz und startete eine Runde zur Zusammenarbeit von FOSSGIS mit BKG und ZenDIS. Ziel soll sein, die Open Source Geocommunity besser zu vernetzen und zu informieren. Insbesondere soll das Repository OpenCode.de für Geotools eine vom FOSSGIS und BKG unterstütze Kuratierung sowie zusätzliche Keywords erhalten. Die soll öffentliche Verwaltungen bei Beschaffungsprozessen zu unterstützen. Eine Strategie des gemeinsamen Vorgehens wurde besprochen.

Passend hierzu diskutierte eine andere Gruppe zur Frage “Wie unterstützen wir Projekte beim Wegzug von GitHub & Co” darüber welche Repositories die Souveränität für FOSSGIS-Projekte gewährleisten und wo und wie der FOSSGIS e.V. unterstützen sollte.

Community-Themen

• Das BKG hat für Produkte der VG25 den Ergänzungstext Addendum der “CC-BY 4.0 - Namensnennung” ergänzt.
• Der Erfahrungsaustausch zu aktuellen Entwicklungen und zur Panoramaxinstanz wurde fortgesetzt. Marc schildete seine Vorgehensweise und gab nützliche Hinweise.
• Hartmut macht sich Gedanken um den Nachbau der OpenSeaMap im Mapnik, um den OpenSeaMap-Stil auch für den Kartendruck mit print.get-map.org anbieten zu können.
• Die Idee, OpenStreetMap als beste Karte für den Nico Rüpke-Kartographie-Preis, der im Rahmen der DGfK verliehen wird, vorzuschlagen, wurde diskutiert.
• Florian bereitet eine Präsentation für Menschen vor, die nicht mit Open Source vertraut sind und sammelt Input.
• Paul hat seinen Job als GIS-Koordinator ein einer Stadtverwaltung begonnen und die Gelegenheit genutzt sich von den Anwesenden hilfreiche Tipps und ein Update zu aktuellen Themen zu holen.
• Peter präsentierte im Thema " Vom Schlagloch zur offenen Karte" seine Ideen und Fragen und besprciht weiteres Vorgehen mit der Gruppe.

Auch wenn das Wochenende gefühlt kurz war, wurden viele Themen besprochen und vorangetrieben. Die Anwesenden wissen die offenen und konstruktiven Gespräche sehr zu schätzen. Gearbeitet wurde im großen und kleinen Seminarraum, Kaminzimmer oder einfach im Garten auf der Wiese. Dazu kamen die traditionelle Pizza am Freitagabend, gemeinsames Kochen und Essen mit spontanen Gesprächen über allerlei Themen. Samstag gab es noch einen Kinoabend mit einem unterhaltsamen Vortragsvideo von den Datenspuren über die Untersuchung von Drohnen in der Ukraine.

Wir danken den Teilnehmerinnen und Teilnehmern für die tollen Beiträge und die tatkräftige Unterstützung bei der Organisation. Ganz besonders danken wir dem Linuxhotel für die Gastfreundschaft!

The problem

I’ve recently found myself with a lot of free time without internet access, and what better to do than improve OpenStreetMap!

JOSM has the capability of “editing offline”, that being that it can download and upload OpenStreetMap data whenever you’d like so if this was simple POI editing then I’d be fine: download the OSM data beforehand in JOSM, make my edits on a blank background and then upload when I have an internet connection again.

But this leaves out aerial imagery, by default JOSM streams this from tile servers, you can look at these URLs in Edit -> Preferences -> Imagery.

Others’ work

The method I have found to get offline aerial imagery is based off of an old forum post which recommends using KDE Marble to download tile data, and then point JOSM at that downloaded data using a file:// link.

This method works! And is the inspiration to mine but there is one fatal flaw in KDE marble that makes it unsuitable for this - it maxes out at zoom 16, inadequate for most mapping activities. I looked in to changing this arbitrary limitation in their source code, but I instead found a much simpler solution…

The breakthrough

Someone has (quite possible vibe-coded) a tool called MapTilesDownloader that fits the bill quite nicely. It can download to arbitrary zoom levels and, as it’s a Python script, it can be easily modified to download from imagery sources other than the ones it comes with.

It’s usage is simple: git clone the repository (git clone https://github.com/AliFlux/MapTilesDownloader.git) then install it’s dependencies: Pillow and Pyvips using pip and run it with python src/server.py and open the displayed URL in your browser. If you want to download Bing or Esri imagery then this is all you need to do, but I needed more obscure imagery.

To add custom imagery to this tool you can modify the sources dict in src/UI/main.js with an imagery URL obtained elsewhere, I got mine from the aforementioned JOSM preferences. The format used for pre-existing ESRI imagery is what most tile servers will use but you can use any of the imagery sources there as an example.

Using this imagery in JOSM

To use the imagery obtained using MapTilesDownloader in JOSM, you simply go to the JOSM imagery settings (Edit -> Preferences -> Imagery) and add a TMS source (plus button on the right) filling in the max zoom that you downloaded and then the URL is the path to the images prefixed with file://. This path is output in the console while the maps are being downloaded, for example on Linux it might be file:///home/<yourUserName>/Downloads/MapTilesDownloader/src/output/1792334342142/{zoom}/{x}/{y}.png with the last three arguments being automatically replaced by JOSM. Save and then your new imagery will be available under Imagery -> <the name you entered>

I hope this information will be of use to someone! Please don’t download too big of a bbox using the imagery downloader tool… And happy mapping!

Mapping

• Two tagging proposals, related to graffiti, are open for voting until 26 October 2026. Evyy is proposing a dedicated tag, shop=graffiti, for shops specialising in spray cans, markers, stickers, and other street art supplies, which have often been tagged as shop=craft or shop=paint in the past. Flappiegrrr is proposing to use leisure=graffiti_wall to record places where graffiti may be sprayed legally, and to describe individual walls using the key graffiti_wall=*.

Community

• [1] Altilunium has developed ‘Know Your Mapper’, a web app that explores an OSM mapper’s editing sessions and approximate areas of activity.

• The small team behind OpenClimbing: Jan Václavík, Pavel Zbytovský, and Fabian Weisshaar, have created their second bot proposal to clean up climbing-related tags in OpenStreetMap. Running with assistance from Mateusz Konieczny, the bot aims to improve the consistency and quality of OSM climbing data. OpenClimbing uses this information to power its specialised map with integrated topos for the climbing community.

• Keagan van Rooyen described how he decided to contribute code to the CoMaps project and is currently working on several additional features for the Android Auto platform.

Events

• Sozialheld*innen has developed the a11y-Score, a score that makes the accessibility of public services in any chosen region comparable, based on open data from OpenStreetMap (we reported earlier). They will be presenting it at an online event on Monday 26 October 2026, from 14:00 to 15:00 CEST.

• Open Energy Transition will host a one-hour webinar introducing EarthPV, a tool that combines free Sentinel-2 imagery, the TerraMind geospatial foundation model, OpenStreetMap, open building datasets and human mapping to identify rooftop and ground-mounted solar installations above 10 kWp. The webinar will present the methodology and prototype results using Pakistan as a case study, and explain how the globally applicable workflow can support other contexts and research.

• Stefan Keller announced ► that there will be a PostGIS and PostgreSQL course on 5 and 6 November 2026 at OST’s Rapperswil campus in Switzerland. The two-day practical course covers PostGIS database administration, data import and conversion, spatial SQL, modern SQL features, performance tuning, and extensions such as pgRouting and pgVector.

• The eighth State of the Map Latin America will take place in person in Mexico City, Mexico, from 27 to 29 October 2026. You can find the full session schedule here .

OSM research

• HeiGIT presented a new paper introducing ACTION, a framework for making remote sensing and volunteered geographic information, including OpenStreetMap data, more useful for decision-making. The paper explored how combining satellite observations with local knowledge can support more transparent, reliable, and actionable geospatial workflows.

Maps

• Eugene Muravjev has built an interactive 3D map of Yas Island. The map uses OpenStreetMap data for roads, buildings, parks, and shorelines, supplemented by building footprints from Overture and Microsoft, and vegetation data from Copernicus Sentinel and ESA WorldCover. Major landmarks, including Ferrari World, Yas Waterworld, Etihad Arena, and the F1 circuit plus its tunnels, are modelled by hand using photographs.

• Goldilocks Map shows how many days a year the weather matches your own idea of comfortable (temperature range, humidity limit, and sunshine) for every place on Earth. The interactive map is built with MapLibre GL JS on OpenFreeMap tiles (OpenStreetMap data) and its climate numbers are checked against NOAA station records.

• Historic.place has been migrated from OpenLayers 2 to Leaflet (via Forum ).

• The Milan City Council’s Citizens’ Advisory Committee on Active Mobility and Accessibility has created a uMap showing all the cycle racks in the municipality of Milan.

• Sven Geggus added support for shelters, except those with sleeping=no, to OpenCampingMap (via Mastodon).

• The Birding Discovery team has developed birding.live, a free website that helps users discover common bird species and nearby birding locations worldwide using OpenStreetMap data.

• TectonicPlateMap.org launched an global interactive web map built with MapLibre GL JS and OpenStreetMap vector tiles. The web app visualises all 52 tectonic plates from the PB2002 dataset, active fault lines, real-time USGS earthquakes, and Smithsonian GVP volcanoes.

• Vienna Living Map is a free housing map of Vienna built on OpenStreetMap: Protomaps vector tiles, OSM points of interest, and cycleways. For every address it calculates the hours of direct sun per floor from OSM building outlines and the City of Vienna’s measured roof model.

OSM in action

• Rasmus Jaakonmäki released Fontavio, an app that maps drinking water, refill taps, toilets, showers, self-service laundries, dump stations, and marina pump-outs across Europe, USA, and Canada. The data come from various sources, including OpenStreetMap, national open datasets, and places added directly by Fontavio users. Each place records its source while the OpenStreetMap data are credited under the ODbL licence.

• The ALIS Project is developing ALIS, an open-source survival game set in real cities. In its latest prototype, the team has built a virtual Manhattan using Unreal Engine 5 and OpenStreetMap data, featuring 109,486 buildings, 84,096 road segments, and 28,265 trees.

Open Data

• Wikimedia Enterprise has released an open geospatial dataset that contains 17 million OpenStreetMap elements linked to Wikidata, Wikipedia, and Wikivoyage, as Parquet and GeoParquet files on Hugging Face and Kaggle.

Software

• Jake Low reported several MapRoulette security vulnerabilities that exposed OpenStreetMap access tokens, API keys and users’ email addresses. He took the application offline for around 15 hours, revoked all credentials and released version 4.11.0 with fixes on 7 October. Users must sign in again and re-authorise MapRoulette with OSM, but do not need to change their passwords.

• OpenHistoricalMap’s vector tiles have had many improvements over the past few months, including Simple 3D Buildings, goodies for golf mappers, and non-administrative boundaries (such as time zones, dioceses, and self-governing indigenous territories). Some of these are breaking changes for existing third-party stylesheets.

• Chris has been developing an AI-assisted OpenStreetMap mapping tool for Windows using Rust, Python, and WGPU for 3D features, with SAM 3 and YOLO models to detect features in satellite imagery from multiple sources, and is seeking community feedback.

• Felis Pimeja has been working on the OSM Simple 3D Editor, a browser-based editor for OpenStreetMap buildings and indoor objects.

• Martin Lange has developed TRAMP (Track and Route Analysis, Mapping and Planning), a free and open-source desktop application for Windows, Linux, and macOS that allows users to explore GNSS tracks and plan routes on OpenStreetMap-based maps using Valhalla or OSRM for routing and Photon or Nominatim for search.

• HeiGIT introduced the Sketch Map Tool on LinkedIn, a low-tech solution to support community mapping through offline data collection, digitisation, and georeferencing of local information. The tool enables users to create and analyse paper-based maps using OpenStreetMap data and satellite or drone imagery from OpenAerialMap.

Releases

• Over the past months Johan Morganti has been building a tool to explore every OpenStreetMap changeset since 2005, see trends over time, and drill down to who did what. This tool ingests OSM’s minutely changeset and diff replication from planet.osm.org, plus the full changeset history: 190 million changesets and 19 billion object changes, from 2005 to a few minutes ago.

• HeiGIT announced the release of ohsome 2.0, introducing major improvements to the ohsome API, ohsome quality API, and dashboard for faster analysis and extraction of historical OpenStreetMap data. The article highlighted the new features and provided guidance for migrating from v1 to v2.0 before the legacy services are discontinued on 30 November 2026.

Other “geo” things

• Safwat Halaby developed maplibre-gl-three, a library that enables developers to add 3D models and 3D tiles at geographic locations in MapLibre GL JS.

• Working with voluntary and community organisations for some is a very important way to do geography. In a guide published by the Royal Geographical Society, there are case studies done in collaboration with community and voluntary organisations. The PDF is available.

• Open Geospatial Solutions has developed RustGIS, a free and open-source GIS in pure Rust for mapping, analysing, and sharing geospatial data.

• GMX reported how a couple got lost in Lost Dutchman State Park in the US state of Arizona after using Google Maps. The pair later called for rescue and were airlifted out by helicopter. In a similar incident, one person died in Yogyakarta, Indonesia, after a car carrying 16 people veered off the road while attempting to navigate a steep incline, following directions from Google Maps.

• The United Nations Office for Disaster Risk Reduction has developed the STOP DISASTERS game. Through play, users explore how decisions about where people live, how buildings are constructed, how ecosystems are protected, and how communities prepare affect what happens when a hazard strikes. The game was originally made as part of the 2006–2007 World Disaster Reduction Campaign, ‘Disaster Risk Reduction Begins at School’.

• The Tiroler Tageszeitung reported (paywalled) on a rival’s map, which has assigned names to places, mountains, and paths in Tyrol and Bavaria that nobody in the local area recognises, such as the ‘Schmusbichl’ in Kaunerberg. Local historians and the Tyrolean Nomenclature Commission are having to use old maps to fight against renaming at the click of a mouse. Donald Trump would probably welcome this as a model to follow; after all, he too has shown that a golf course can quickly be given a new name if you just have the right map in hand. In OpenStreetMap, by contrast, names continue to be assigned based on local knowledge.

可不能“随手一标”！

来源：国家安全部 2026年10月17日07:03 北京

https://mp.weixin.qq.com/s/Xri2QFc-6VPpZ6QLBaqjgw

一张看似普通的网络地图，一个出于“兴趣”的随手标注，竟可能危害国家秘密安全。近年来，随着地理信息技术的普及，“开放地图”平台逐渐走入公众视野，但其背后隐藏的国家安全风险却不容忽视。

一个“爱好”带来的麻烦

2021年，许某在社交媒体上被一张带有艺术风格的路网地图所吸引。出于好奇，他开始接触境外开放地图平台，并违法“翻墙”访问。许某凭借对居住地周边环境的了解，以及从互联网搜集的公开信息，开始在境外开放地图平台上标注各类地理信息，多次标注军队等涉密敏感单位的位置信息。国家安全机关发现许某违法行为后迅速采取行动，依法对其开展审查。面对审查，许某懊悔道：“我完全没想到，自己只是出于爱好做点标记，竟会触犯法律，威胁国家安全。”国家安全机关向其宣讲了相关法律法规，讲明了其行为的危害性，并依法对其进行处理。许某表示已深刻认识到错误，并积极配合消除隐患。

随手一标，隐患巨大

“开放地图”一般指数据开源、可自由使用与编辑的地图项目，经常由全球志愿者共同创建、编辑并免费共享地理数据，在碳中和、城乡交通建设、灾害风险评估研究等方面具备相应应用价值。但如果在开放地图平台上标注我国涉密敏感地理信息，就有可能被不法分子利用，对我国家安全造成危害。不法分子无需动用复杂的技术手段，仅凭开放地图便能轻易获取我国涉密敏感单位的位置、规模等信息，并据此在军事基地等涉密敏感单位附近开展“黑飞”、偷拍、测绘等活动。境外间谍情报机关还可能结合其他渠道获取的信息进行多源数据交叉比对，拼凑成完整情报，甚至还可能对涉密单位工作人员以及周边居民、商户等人员开展针对性的渗透、拉拢和策反活动，对我国家安全构成严重威胁。

国家安全机关提示

《中华人民共和国保守国家秘密法》《中华人民共和国测绘法》《公开地图内容表示规范》等法律法规划出清晰底线：个人或者组织非法获取、持有、提供、利用属于国家秘密的地理信息的，将被依法追责。开放地图不是个人兴趣的“涂鸦板”，看似无心的标注可能触碰国家秘密“红线”。

——绷紧“安全弦”。增强国家安全意识，不在地图平台标注任何涉及军事基地、涉密单位的地理信息。

——把好“出口关”。不在社交平台发布涉密场所周边照片、视频，拍照前留意背景是否涉及敏感场所，不转发、不扩散任何标注有涉密地理信息的地图内容。

——当好“守护者”。如发现在公开地图标注涉密地理信息等危害国家安全的可疑情况，请及时通过12339国家安全机关举报受理电话、网络举报受理平台（www.12339.gov.cn）、国家安全部微信公众号举报受理渠道或者直接向当地国家安全机关进行举报。

I made this fun little editing showcase! Enjoy!

Er is hier nog veel te doen:

• Straten missen veel properties, zoals surface, lane_markings, smoothness en sidewalks.
• Huisnummers ontbreken, zijn wel goed zichtbaar.
• trappen missen properties
• zebrapaden ontbreken op veel plaatsen
• Bedrijven staan niet in de kaart of zijn verandert Kortom nog veel eer te behalen en relatief snel resultaat.

Ook in de buurt, laat het me weten

In this edition of our OpenStreetMap interview series, we spoke with Sofia Pahaoja, creator of Touch Mapper, a project that uses OpenStreetMap data and 3D printing to create tactile maps for visually impaired people.

1. Who are you, what do you do, and how did you first get involved with OpenStreetMap?

I’m Sofia Pahaoja, a Finnish software engineer. I’ve been programming since I was young. I’d known about OpenStreetMap for a long time, but hadn’t used it much until I started working on Touch Mapper about ten years ago.

2. Can you tell us about Touch Mapper and what inspired you to create it? How did OpenStreetMap and 3D printing come together in the idea behind the project?

Touch Mapper is a website where you can create tactile maps for visually impaired people for free, if you print them yourself. Both 3D printing and embossing on paper are supported.

I created Touch Mapper because my partner was visually impaired, and spending time with her made me realize that there were virtually no usable tactile maps for that group of people, and that creating them from OpenStreetMap data wouldn’t be that difficult.

We were on vacation in Rome, and I wanted to explain to her the layout of the neighborhood around our hotel. But words couldn’t really convey it. About all I could say was, “It’s a maze of narrow streets.” There are simply no substitutes for a map, be it visual or tactile.

For many visually impaired people, being able to explore an area using a map offers an entirely new way of understanding their surroundings. A tactile map can be extremely useful in practical ways, but it can also offer the same joy that anyone might get from studying a map out of curiosity.

She was enthusiastic about the idea of Touch Mapper and played an important role in testing it throughout the initial development.

As far as I knew, there weren’t any other practical sources of map data besides OpenStreetMap. Google Maps existed, of course, but it didn’t offer the same access to reusable geographic data that I needed.

3. Touch Mapper uses OpenStreetMap data to create tactile 3D-printed maps. What makes OSM particularly well suited to this kind of accessibility project?

Besides being one of the few practical sources of map data, OSM has an important advantage: anyone can improve it.

Most maps generated using Touch Mapper are created by professionals who work with visually impaired people. If they find that important information is missing, they can add it to OpenStreetMap and then generate the map they need.

4. What have you learned about OpenStreetMap through working with it for Touch Mapper? Are there particular features or types of map data that are especially important when creating maps for people who are blind or partially sighted?

OpenStreetMap contains a wealth of information. Pedestrian paths are generally more important than roads for tactile maps, and sometimes those are missing. Pedestrian crossings are also important, but aren’t always mapped.

Another lesson has been that the geometry described by OSM isn’t always suitable for 3D printing. Roads and buildings can overlap, or the data may contain geometries that simply don’t make sense.

A visual map can tolerate all kinds of geometric imperfections, because it’s ultimately just drawing shapes on a screen. But a 3D-printed map needs to consist of physically valid, printable solids. Overlapping shapes, tiny gaps, and other geometric inconsistencies can cause problems when generating a printable model.

In practice, most of these issues can be handled automatically, but it requires treating the data as something that may need cleanup, and using heuristics to make tiny adjustments to the geometry.

5. You mention that missing buildings and other inaccuracies in OSM can affect the resulting maps. What challenges have you encountered with OSM data, and what could the OSM community do to make the map more useful for accessibility applications?

Generally, the biggest problem is simply missing data, whether that’s buildings, roads, or pedestrian paths. Users rarely complain about this, though. My impression is that they don’t expect the underlying map data to be perfect.

One important limitation is indoor mapping. Many practical needs of visually impaired people involve navigating indoor spaces, such as finding a particular store in a shopping mall.

Indoor spaces would probably require a rather different approach to tactile map creation. My impression is that the indoor mapping data available in OSM isn’t yet complete or consistent enough to make this a worthwhile addition to Touch Mapper, though I haven’t investigated the matter very thoroughly.

6. Touch Mapper shows one interesting way that OpenStreetMap data can be used beyond a traditional digital map. What other possibilities do you see for OSM in accessibility, tactile mapping, or other applications that the community might not have considered?

A recent addition to Touch Mapper is textual description of the selected area. This enables a visually impaired person to verify that they have selected the correct area for the map. But it could also answer questions such as “What points of interest are there near my home or place of work?”

Chatbots could also be an excellent interface for visually impaired people. Their text-based interfaces work well with screen readers and braille displays, allowing people to ask questions in natural language.

I’m not sure how much access chatbots currently have to OSM data, but questions like “Describe the walking route from my home to this bus stop”, “List the most important points of interest near this address”, or “Is there a park between the station and the library?” could benefit enormously from having API access or another way of querying structured OSM data.

Imagine a blind person who has just moved to a new neighborhood. They could ask a chatbot what’s around their new home, where the nearest shops and parks are, and how the streets connect to each other. They could then ask follow-up questions, gradually building a mental picture of the neighborhood without ever needing to see a map.

This would go beyond simply giving directions from one place to another. It would make exploring and understanding the geography of a place a much more accessible experience.

7. Looking ahead, what would you like to see happen with Touch Mapper and OpenStreetMap over the next 10–20 years, particularly in making geographic information more accessible to people with different needs?

Indoor maps, definitely. Finding your way around a shopping mall, an airport, or a university building can be very difficult without sight, and having good indoor map data could make a huge difference.

Routing is another possibility: step-by-step walking directions designed specifically for visually impaired people. This requires more than just knowing where the streets and paths are. Information about pedestrian crossings, stairs, entrances, and other details can be essential.

More broadly, I’d like to see geographic information become something everyone can explore, regardless of how they perceive the world. Maps are traditionally visual, but the underlying information doesn’t have to be presented visually. It can be turned into tactile maps, spoken descriptions, or interactive conversations.

I hope that in 10 or 20 years, a blind person will be able to explore an unfamiliar city with much the same freedom and curiosity as a sighted person looking at a map. OpenStreetMap could provide much of the data needed to make that possible.

Thank you, Sofia! It’s inspiring to see how OpenStreetMap can help make geographic information more accessible and give visually impaired people new ways to explore and understand the world around them.

Please let us know if your community would like to be part of our interview series here on our blog. If you are or know of someone we should interview, please get in touch, we’re always looking to promote people doing interesting things with open geo data.

Im Jahr 2023 war ich, Katja Haferkorn, das erste mal auf der Smart Country Convention und hatte es kurz in einem Blogpost festgehalten.
Nach dem Besuch der diesjährigen SCCON, die vom 13. – 15. Oktober 2026 in den Messehallen Berlin stattfand, ist die damalige Vermutung “Möglicherweise macht es Sinn als Verein zukünftig in irgendeiner Weise vertreten zu sein.” von vielen Seiten bestätigt worden.

Open Source Park

Die Open Source Business Alliance (OSBA) hat einen Open Source Park organisiert und die geballte Open Source Kompetenz im OSS-Park versammelt. Dort präsentierten sich Mitglieder der OSBA mit ihren Dienstleistungen und Lösungen. Unter anderem war die Civitas-Connect-Community vertreten und präentierte ihre Lösung und Mitgliedspartnerschaften. Vielleicht präsentiert sich Cititas Connect auch auf der FOSSGIS 2027.
Eine für die FOSSGIS-Community interessante Initiative ist der Sovereign Cloud Stack, der von zahlreichen Dienstleistern angeboten wird.
Am Pretix-Stand hatte ich Gelegenheit mich zum Shopsystem, welches wir für die Konferenztickets und weitere Veranstaltungen einsetzen auszutauchen sowie das Team zur FOSSGIS-Konferenz nach Heidelberg einzuladen, da der Firmensitz in Heidelberg ist.

Open Source Park auf der SCCON 2026

FOSSGIS e.V. am lat/lon-Stand

Die lat/lon GmbH, auch Mitglied in der OSBA präsentierte sich an einem Stand. lat/lon Gesellschaft für raumbezogene Informationssysteme mbH ist Mitglied im FOSSGIS e.V. und gab dem Verein Gelegenheit sich mit zu präsentieren sowie etwas Werbematerial auszulegen.
Der Stand war gut frequentiert, viele kamen gezielt, um sich Informationen zu Geofragen zu holen, ein Treffpunkt der FOSSGIS-Community entstand.

Das lat/lon-Team freute sich, dass Katja Haferkorn, als Vertreterin der FOSSGIS e.V. Koordinierungsstelle mit am Stand war und Fragen zum Verein und zur Konferenz beantworten konnte, u.a. ist der Oktober ein günstiger Zeitpunkt, um Werbung für die Konferenz zu machen. So manche freute sich Informatioen zum Call for Participation oder eine Erinnerung an die Einreichung zur FOSSGIS 2027 zu erhalten, die Einreichefrist endet am 01.11.2026. Es ging darum, welche Themen für die Konferenz interessant sind und was die Teilnehmenden von dieser riesigen Veranstaltung mitnehmen könnten.

Der lat/lon-Stand im OSS-Park entwickelte sich zum Treffpunkt der FOSSGIS-Community

Geothemen auf der SCCON

Auf der SCCON sind viele für die Geocommunity interessante Initiativen und Institutionen vertreten. Zahlreiche große Dienstleister, insbesondere KI- und Cloudanbieter bieten ihre Dienste an und an fast jedem Stand wird Digitale Souveränität versprochen. Wer hier versucht den passenden, digital souveränen Weg herauszufinden, lässt sich vom Zentrum für Digitale Souveränität (ZenDIS), der OSBA oder dem FOSSGIS e.V. beraten.

Das Bundesamt für Kartographie (BKG) war mit einem Stand dabei und präsentiert den Digitalen Zwilling Deutschland, die GDI-DE, die GEO.KI sowie weitere Projekte.

Unbedingt erwähnt sei Smart City Wuppertal, die mit einem großen, anschaulichen Modell von Wuppertal Aufsehen dahingehend erregt hat, dass dieses sowohl die städtische Infrastruktur, wie Straßen, Schwebebahn, Wupper, Siedlugen und Wald sehr schön darstellte und auch vorhandene Geodaten über einen Projektor projeziert wurden. Damit ist es möglich Echtzeitdaten oder auch Simulatonsdaten einzuspielen, es können Hochwasser-, Schattenwurfszenarien oder die Stadtbeleuchtung eindrucksvoll dargestellt werden.

Smart City Wuppertal im interaktiven Modell

FOSSGIS e.V. zur SCCON 2027 dabei?

Angenommen der FOSSGIS e.V. hat einen Stand im Open Source Park und präsentiert dort sein Spielfeld und die Player. Das könnte es dahingehend erfolgreich werden, dass wir gebündelte Geo-Kompetenz für Open Source zeigen, vielfältige Ansprechpartner verfügbar wären und es auch noch Spaß macht. Dies sollte innerhalb des Vereins besprochen werden, um einen passenden Auftritt zu erreichen.

Pierpoint is a small town in South Dakota. It’s now mapped: buildings, sidewalks, footpaths, alleys, power poles. There is probably more micro mapping to do but it’s on the map now.
