For ages, I’ve been wanting to tell my stories around a specific place in OSM. Not specifically a “review” of a business, but simply a personal anecdote about me and that particular place.

Years ago, I received my first invitation to give a talk about OSM. On that occasion, I proposed this project: “What if we create a platform where people can share their personal stories around a specific place?”

But I was probably just an “idea guy” back then.

My programming skills weren’t developed enough to build the platform all by myself, and I had no idea how to get funding to pay for a hosting service anyway. So I shelved the idea for a long time.

Fast-forward to 2026, I eventually thought to myself: maybe it’s finally the right time to revisit that old dream.

So I built this.

First, you log in using your OSM account.

I want this platform to be somewhat of an extension of OSM Diary.

Here, you can not only write an “OSM Diary” entry associated with your OSM account, but also link it to a specific place. Every story is tied to a particular location. If a place is significant enough that many people have posted their stories about it, you can see all the other stories associated with that place.

Then, you have three ways to choose a place. You can search for it using the “Search places with Photon” feature. You can manually zoom in on the map and pick a location. Or you can use the GPS button to automatically zoom to your current location.

Then, pick a location and write your story.

Alright. Day two. As I finally have some free time to write this one.

At 2:27 pm, I went to the Martinique room, planning to attend the “OSM Science” opening talk.

At 2:37 pm, I saw a slide showcasing the QR codes for each OSM Science output, starting from 2019 to 2025 (including the IJGI special issue).

I went back and forth, decoding all those QR code links one by one, and posted them on my Mastodon.

• https://www.mdpi.com/journal/ijgi/special_issues/OpenStreetMap

The Q&A session started at 2:51 pm, and finally ended at 2:58 pm.

After that, I stayed in the Martinique room. The researchers who had submitted their publications to OSM Science started presenting their work, one by one, in quick succession, around five minutes each.

Around 3:02 pm, I had to close the stream for a little while because I had something to do.

I came back at 3:38 pm, still in the Martinique room. The OSM Science paper presentations were still ongoing, and finally ended around 3:44 pm.

Then, it was coffee break (10:44 am Paris time). The programme said it would resume at 11:15 Paris time.

I closed the stream, killed some time by editing WeeklyOSM, then came back at 4:12 pm, this time in the Corse room.

The talk had not started yet. It finally began at 4:15 pm.

The topic was very interesting: how to make your GNSS (a.k.a. “GPS”) reach centimeter-level accuracy.

Turns out, you need special hardware and a special “network to distribute GNSS correction streams”.

The talk ended at 4:43 pm.

At 4:44 pm, I went back to the Martinique room. The next talk started at around 4:50 pm, this time about visualizing lanes in road networks. Really interesting.

When I edit WeeklyOSM, I sometimes come across several contributors who are working on this exact same problem: how to properly visualize lanes in the OSM road network.

And this problem is really complex. Sometimes, for example, you need to account for the width of each road’s geometry, which can even vary along a particular segment.

The talk ended at 5:18 pm.

At 5:22 pm, I went to the Corse room. This time, the talk was about the “Fédération des pros d’OpenStreetMap” (FPOSM).

From the talk description, it is “a French non-profit organization that unites companies and professionals whose services and tools are built on OpenStreetMap, and who are committed to keeping OpenStreetMap a healthy digital commons”.

I discussed this talk quite a lot in the internal HOT chat group while watching the stream online, especially the possibility of starting a similar organization ourselves.

At 5:48 pm, I had to close the stream again because I had something to do.

At first, I planned to rejoin at around 8 pm, but then I got an urgent invitation from my neighbor to attend an event. So I tried to watch the stream on my mobile phone while traveling outside, around 8 pm, in the Guadeloupe room.

It was one of the talks that I really wanted to watch. It was about OpenStreetMap’s “core software” projects, explained by the key people behind those projects themselves.

Unfortunately, I failed to watch the rest of the talk, since the neighbor’s event was starting soon. So I had to close the stream and move on.

Thankfully, as I am writing this OSM diary right now (September 9th, while the second day was August 29th), the full recording of that talk is already available on the SOTM 2026 website, hosted by OSM France’s PeerTube instance.

Well, I think I want to watch the video in full first before continuing this OSM diary…

Online-Konsultation für einen weiterentwickelten Rahmen für Open Data

Die Bundesregierung plant, den strategischen Rahmen für Open Data weiterzuentwickeln. Das Bundesministerium für Digitalisierung und Staatsmodernisierung lädt daher die Open-Data-Community, Stakeholder und die interessierte Öffentlichkeit zu einer Online-Konsultation ein.
Ziel dieser Konsultation ist es, Vorschläge und Anregungen für einen weiterentwickelten Rahmen als „Fahrplan für Open Data“ zu sammeln. Die Bundesregierung strebt die Verabschiedung und Veröffentlichung für Anfang 2027 an.

Mitglieder aus dem FOSSGIS e.V. haben anhand der Leitfragen die wichtigsten Aspekte, Themen und Handlungsfelder zusammengetragen, woraus eine Stellungnahme entstanden ist, die fristgemäß eingereicht wird.

Danke an alle, die unterstützt haben.

Hier ist die komplette Stellungnahme zum Nachlesen und Herunterladen als PDF.

Wrapping up GSoC 2026: Making closures.osm.ch production ready

This summer I had the chance to spend my second Google Summer of Code working with the OpenStreetMap Foundation, this time on closures.osm.ch, a community platform for reporting temporary road closures in real time so that routing engines can actually route around them.

closures.osm.ch started life during GSoC 2025 as a solid prototype: a FastAPI backend, a Next.js frontend, OpenLR location referencing, and a first attempt at routing integration with Valhalla. My job this summer was to take it from “working prototype” to something closer to a real production service.

The routing problem

The biggest issue going in was architectural. The frontend was fetching closures, pulling out raw coordinates, and handing them to the public Valhalla instance as exclude_locations. It worked, sort of, but it had a hard 49-point cap, ignored one-way closures entirely, and duplicated business logic between two different frontend components. None of that scales.

Before writing any code, I actually went and discussed the right approach with the Valhalla maintainers themselves in a public GitHub discussion. That conversation confirmed the long-term correct architecture is Valhalla’s live traffic tile infrastructure rather than anything at the exclude_locations level. That’s a bigger undertaking than fits in one summer, so the plan became a two-stage one: build a solid stepping-stone now, leave the graph-level integration properly documented for later.

That stepping stone is what shipped: a self-hosted Valhalla instance, and a new backend endpoint that buffers closure geometries with Shapely and passes them to Valhalla as exclude_polygons instead. The frontend got a lot simpler as a result, it just asks for a route now and gets one back with closures already avoided, no more duplicated logic living in the browser.

OpenLR, for real this time

Somewhat embarrassingly, the OpenLR codes the platform was generating weren’t actually spec-compliant OpenLR, they used a custom marker byte that no standard decoder could read. That’s now fixed, with encoding going through Valhalla’s map-matching, so closures.osm.ch’s location references should now interoperate with other OSM-based navigation tooling that speaks real OpenLR.

Vector tiles

Active closures are now served as MVT vector tiles straight out of PostGIS with ST_AsMVT, so the map layer updates live instead of requiring a page reload. Small feature, but it makes the map feel a lot more alive.

What’s left

Government data ingestion is the piece I didn’t get to finish. The plan was CIFS and DATEX II importers so the platform could ingest authoritative closure data from municipal agencies directly, but partway through the summer that scope shifted: OST offered to push pre-processed Swiss ASTRA data to us directly instead of us having to parse it ourselves, which changes the shape of that work. I’ve made a start on it, but it’s genuinely not done, and I’ll be continuing on it after GSoC officially wraps up. UI internationalisation is also still untouched, it’s documented as deferred work for now.

Thanks

Huge thanks to my mentors Simon Poole and David Haberthür for the guidance this summer, and for trusting me to make real architectural calls on a project that real people depend on. Also thanks to the Valhalla maintainers for taking the time to talk through the routing architecture with a stranger on the internet before I’d written a line of code.

If you want the full technical rundown with links to every PR, I’ve written that up separately in the project’s final report.

Development on closures.osm.ch continues, I’m not stopping here.

Sou um usuário novo, e desde que comecei a editar locais que conheço, acabei não lendo a guia de direitos de autor, onde indica-se que sites como Google não deverão ser usados para preencher informações. Acabei cometendo esse erro, e peço minhas sinceiras desculpas pelos erros que cometi. A partir de agora, estarei usando os sites oficiais do município e os sites oficiais das instituições e prédios que irei adicionar, junto com fotos aéreas e, se eu puder, visitarei esses lugares.

I sincerely apologize for my lack of reading the guide for this website when I shouldn’t use map sites related to Google. I’m lazy at first when I tried to use the site for the first time. Especially for mapping broadcast stations, and missing barangays for like 9 months now.

In 2026, the question is no longer really:

“Can OpenStreetMap truly be used professionally?”

State of the Map 2026 in Paris once again showed that this question has largely been settled.

OSM now serves as the foundation for national reference datasets, is influencing European standardisation work on cycling infrastructure, supports research into data quality, and is part of an increasingly structured professional ecosystem.

Around it, other digital commons are also emerging, such as Panoramax.

At the same time, some talks reminded us of something essential: behind tags, ontologies and data pipelines, a map remains a representation of the world — and therefore the result of choices.

A few reflections, with a cycling-data bias, after three days at #SOTM2026 at Géodata Paris 👇

(french version here)

State of the Map Paris 2026: OpenStreetMap is scaling up

For the first time, the global State of the Map conference took place in France, from August 28 to 30, 2026, in Champs-sur-Marne, near Paris.

The location itself felt quite symbolic. The international OpenStreetMap community gathered at Cité Descartes, including at Géodata Paris, IGN’s school, alongside École nationale des ponts et chaussées and Université Gustave Eiffel.

For three days, contributors, researchers, public authorities, institutions, associations and companies met in a place dedicated to education, research and new uses of geographic data.

This connection between OSM, academia, research, public institutions and professional geodata users actually sums up quite well what I took away from this edition.

A few days after SOTM 2026, one impression stands out:

OpenStreetMap is scaling up.

Of course, OSM has long ceased to be merely “a collaborative map” sitting on the margins of large private or governmental mapping platforms.

But this year’s conference showed particularly clearly how deeply the project is now embedded in professional applications, research, public policy and even standardisation work.

And it was particularly interesting to see this evolution taking place at IGN.

IGN was not only one of the event’s partners. Several topics discussed during the conference — including Panoramax, digital commons and the relationship between institutional datasets and OpenStreetMap — also illustrate a deeper evolution in the relationship between the French institutional geographic ecosystem and OSM.

A few years ago, IGN and OpenStreetMap could easily have been portrayed as two separate, perhaps even competing, worlds. I have quite vivid memories of this opposition from when I studied here myself.

SOTM 2026 told a rather different story:

one of complementarity, commons and collaboration.

Among the many talks, a few topics particularly caught my attention.

OSM is starting to inspire cycling standards

The presentation “How OSM inspires CEN standards for cycling infrastructure”, by Tu-Tho Thai, sent a strong signal.

As part of European work on the digital description of cycling infrastructure, the Cyclinfra project is examining OpenStreetMap tags and mapping practices.

OSM is therefore no longer simply adapting itself to institutional standards.

It is also starting to inspire them.

France’s Base Nationale des Aménagements Cyclables (BNAC) — the National Cycling Infrastructure Database — follows a similar approach: using OSM as a source, transforming the data into a national data schema, and enabling public authorities to improve the shared OSM dataset in return.

For cycling, this convergence between OSM, national datasets and European standards is particularly promising.

It is also very close to what we have been promoting within the Geodata team at Geovelo.

When mapping a pothole becomes political

The discussions around “The democratic stakes of mapmaking”, with Ksenia Ermoshina, Christian Quest and Françoise Bahoken among others, were a useful reminder of something that is often overlooked:

Mapping is a political act.

A simple example illustrates this well.

Mapping potholes or problems in public space may seem trivial. But making those issues visible also makes it possible to assess public policies and helps residents organise or advocate for improvements.

Choosing what we represent, what we describe, and what we leave invisible is already a decision.

Technical choices in a database or a map are therefore never entirely neutral.

Panoramax: a new geographic common

Panoramax was also highly visible throughout the conference — starting right from the opening session.

That was particularly satisfying for us at Geovelo, as we helped fund the first viewer back in 2021, when the project was still called GeoVisio.

Panoramax provides a free, open and federated alternative for sharing street-level imagery.

Its value is not only in the photographs themselves.

Its architecture is equally important: multiple organisations can host their own imagery while remaining connected through a common federation.

Like OpenStreetMap, Panoramax demonstrates that it is possible to build an open, decentralised geographic infrastructure that does not depend on a single provider.

The French Federation of OSM Professionals is helping structure the ecosystem

The French Federation of OpenStreetMap Professionals, of which Geovelo is a member, was also very visible during the event: through its booth, talks, discussions with participants and an OpenStreetMap TV studio.

This reflects another important evolution.

Over the past few years, a genuine professional ecosystem has been developing around OpenStreetMap.

The Federation brings together companies and professionals working in mobility, accessibility, energy, urban planning, tourism, GIS tools, data quality and other fields.

Its purpose is not simply to represent businesses using OSM.

It also builds bridges with public authorities, explains the ODbL licence, documents professional uses of OSM and advocates for the commons-based model.

We also followed several more technical and applied-research topics.

Making OSM easier to use

Jake Low’s presentation “Sourdough and Layercake” addressed another major challenge: OpenStreetMap’s complexity.

Sourdough provides vector tiles that remain close to the logic of OSM tags.

Layercake transforms OSM data into thematic layers, including in GeoParquet format.

The objective is straightforward: allow more people to work with OSM data in tools such as QGIS, DuckDB or notebooks without first having to master the full complexity of PBF files, relations and tagging conventions.

Making OSM easier to access without losing the connection to the original data is probably one of the major challenges facing the ecosystem.

Understanding changes in OpenStreetMap

The work presented by Camille Bernard and Pedro Pinheiro focused on detecting and semantically annotating changes in OpenStreetMap.

Their research was presented as:

Bernard, C., Pinheiro, P., & Viry, M. (2026). Detection and Semantic Annotation of Changes in OpenStreetMap Data. OSM Science 2026 at State of the Map 2026.

Detecting that an object has changed is relatively easy.

Understanding why it changed is much harder.

Imagine that a cycleway suddenly appears in OSM.

Was the infrastructure actually just built?

Was it already present on the ground but had never been mapped?

Was it simply a tagging correction?

Or a geometry improvement?

Being able to distinguish between these situations is essential when analysing how a territory evolves.

This is something we will be following closely.

Comparing the number of kilometres of cycleways in OSM between two dates is not enough. We need to distinguish changes in the real world from changes in how the real world is represented in OSM.

OSM is no longer just a map

Although, to be fair, it probably never was.

All these examples tell a similar story:

• Panoramax is building a new commons around street-level imagery.
• Sourdough and Layercake are making OSM data easier to use.
• The Federation of OSM Professionals is helping structure an economic ecosystem while building bridges with public institutions.
• Research is helping us better understand how OSM data evolves.
• European cycling standards are beginning to learn from OpenStreetMap.
• Discussions about mapping remind us that technical choices can also have democratic consequences.

The question is therefore no longer really whether OpenStreetMap can be used professionally or institutionally.

That has already been answered.

The more interesting questions are now:

• How do we industrialise without closing things down?

• How do we standardise without oversimplifying?

• How do we professionalise without taking ownership away from the community?

That is what I will remember from State of the Map 2026 in Paris.

OpenStreetMap is no longer simply a map that we improve feature by feature.

It is an infrastructure and a digital common around which tools, companies, standards, research and public policies are now being built.

Geovelo at SOTM 2026

We also contributed two presentations during the conference:

• Geovelo & cycling infrastructure, a discussion in the SOTM TV studio, in French.
• “How OpenStreetMap became the backbone of France’s National Cycling Database”, presenting the history of the BNAC and making the case for the relationship between institutional cycling data and OpenStreetMap.

A busy State of the Map, and plenty of ideas to bring home.

See you at the next one!

37 Degrees North & -85 Degrees West

Das Vernetzungstreffen des FOSSGIS e.V. hat am 02.09.2026 mit 25 Teilnehmenden in der Netzwerkwelt stattgefunden. Die Idee ist, das gegenseitige Kennenlernen und gemeinsamer Austausch zu Anliegen und Themen. Menschen im Umfeld des FOSSGIS-Vereins erhalten Gelegenheit Kontaktpunkte zu finden. Viele Teilnehmende waren schon beim letzten Mal dabei und kannten sich in der Benutzung der Netzwerkwelt aus.

Eindrücke vom Treffen, Start im FOSSGISeV-Raum

Spannende Themen im Austausch

Zu Beginn trafen sich alle Teilnehmenden im Raum FOSSGIS e.V. für einen gemeinsamen Einstieg und um den Ablauf der Veranstaltung miteinander zu teilen. Vier Räume waren thematisch vorgeplant.

Die Idee der Vernetzung im Bereich Blaulicht/BOS/Gefahrenabwehr wurde von Jana Thomas und Mirco Schindler weiter vorangetrieben. Es wurden konkrete Schritte bsprochen, um eine Arbeitsgruppe im FOSSGIS e.V. zu gründen. Die Gruppe hat schon eine eigne Mailingliste sowie erste Ideen für den Namen und was erreicht werden möchte.
Auf der SOTM 2026, die Ande August in Paris stattgefunden hat, gab es einen Vortrag passend zum Thema, “Emergency Services using OpenStreetMap in Germany”.

Der diesjährige Geodaten-Hackathon (#hack4GDI_DE) findet vom 13. - 14.11.2026 an der Hochschule Mainz statt. Die Challenge 2 zum Thema Flächenentsiegelung & Schwammstadt wird von Emmanuel Tobey gestaltet. Um den Einstieg zu erleichtern, nutzte Emmanuel das Vernetzungstreffen. Die Gruppe formulierte eine Wikianleitung für einen FOSS-Einstieg beim Hackathon und tauschte sich zum Umsetzungskonzeot aus. Details & Anmeldung zum Geodaten-Hackathon sind auf den Webseiten der GDI-DE zu finden.

Das Thema KI und heterogene Geodaten treibt nicht nur Johannes Lauer um. In der Gruppe geht es um die Frage, kann KI bei heterogenen Geodatenbeständen helfen? Welche Tools gibt es? Welche Use Cases haben sie Teilnehmenden? Als Usecases wurden Softwareentwicklung, Landoberflächenklassifikation oder der Support für non-GIS-Experts und weitere besprochen. Vor- und Nachteile von KI-Nutzung waren Thema, beispielsweise haben die Repo-Betreiber Codeberg e.V. eine Entscheidung zum Schutz der FLOSS-Commons vor LLMs getroffen und hier aufgeschrieben, die CivicDataLab Community hat ein selbst gehostetes KI-Tool auf den Weg gebracht. Das Thema wird beim nächsten Vernetzungstreffen fortgesetzt.

Im Themenraum Praxisbeispiel QGIS-(Analyse-)Werkzeuge stellte Anja Eisert das Sichtbarkeitsanalysetool Visibility Analysis vor. Im Anschluss tauschten sich die Teilnehmenden allgemein zu QGIS-Tools und PlugIns sowie über Weiterbildungsmöglichkeiten und Jobperspektiven aus.

Das Treffen in der Netzwerkwelt hat auf Basis von Workadventure stattgefunden. In der Netzwerkwelt ist die Interaktion von Teilnehmenden möglich, man ist mit einem Avatar unterwegs, gibt sich beim Eintreten einen Namen. Trifft man eine andere Person, öffnet sich ein Videochat, eine Unterhaltung ist bis maximal 4 Teilnehmende möglich. Die Räume (Inselchen) sind Videokonferenzräume, man tritt einem Jitsi-Videochat bei, dort fanden die Austauschrunden statt. Vielen Dank an Stella fürs Bauen der Netzwerkwelt und danke den FOSSGIS e.V. für die Unterstützung des Treffens mit den Entgelt an die Betreiber der Plattform.

Abschluss und Feedback

Abschluss und Feedback

Die Rückmeldungen waren durchweg positiv, die Teilnehmenden kommen wieder und wollen sich weiter über verschiedene Themen austauschen.

Das nächste Vernetzungstreffen am 09.12.2026 wird wieder ab 17:30 Uhr in der Netzwerkwelt starten, um entspanntes Ankommen, ersten Austausch und einen gemeinsamen Beginn um 18 Uhr zu gewährleisten.

Folgende Themen wurden gewünscht und werden voraussichtlich angeboten:

• Fortsetzung Vernetzung BOS/Gefahrenabwehr (Jana + Mirco)
• Beispiele aus der Praxis: QGIS, QGIS Layertool, ArCGIS2QGIS (Anja E., Christian S.)
• Fortsetzung Raumes zu KI und Geodaten, da die Entwicklung so schnell geht, dass regelmäßiger Austausch sinnvoll erscheint (Johannes L.)
• Konzepte studentischer Vernetzung (David.stud)

Wer Interesse hat einen Raum anzubieten, meldet sich bitte vorab bei Katja oder per mail an socialmedia@fossgis.de.

Infos aus dem Verein

Die Aktivitäten des Vereins sind im FOSSGIS-Vereins-Kalender zu finden.

Vom 9.-13-03.2027 findet die FOSSGIS-Konferenz 2027 in Heidelberg statt. Erste Infos sind auf der Konferenzhomepage veröffentlicht, Beitragseinreichungen sind im Rahmen des Call for Participation vom 01.10. bis 01.11.2026 und die Anmeldung ist ab Januar 2027 möglich.

JETZT OSM-Förderer werden und die digitale Souveränität stärken!: https://openstreetmap.de/foerderer/

Das aktuelle Projekt: OSM-Schulungen, gefördert durch die DSEE (transform_D) läuft noch bis Ende 2027. Die Idee ist Schulungsmodule mit Inhalten zu entwickeln. Eine Arbeitsgruppe begleitet den Entwicklungsprozess inhaltlich, erste Schulungen werden zu Beginn 2027 stattfinden. Für die Organisation der Schulungen in der Koordinierungsstelle des FOSSGIS e.V. kommt ab 01.10.2026 eine neue Kollegin.

Das wichtigste zuletzt: Der FOSSGIS-Verein sucht einen Schatzmeister, die Position ist derzeit bis zur nächsten Mitgliederversammlung mit Wahl komissarisch zu besetzen.

Manchmal zoome ich in einen zufälligen Bereich hinein, sehe, dass ein Bereich komplett ungemappt ist, und verbringe dann die nächste Stunde damit, jedes kleine Detail zu erfassen, das ich sehen kann. OpenStreetMap bearbeiten macht süchtig.

So, during my career, I discovered OpenStreetMap. While editing, I used Google Maps and Street View, and I shouldn’t have read the guide, which is not allowed on this site, especially when adding missing barangays.

Whoops. :/

Created account, Labor Day Weekend

good things compared to yesterday: no rain!!

bad things: nearly 30°C outside and So. Many. Bees. okay it wasn’t as many as i make it sound like but i am admittedly afraid of bees. not a great time

ANYWAY. i went and finished the side of thames street that i started yesterday, then did the other half on the way home. so im pretty sure ive accounted for almost everything on that street now! so i guess next on the list is the side streets. hopefully we get some days that are nice and cool so i dont suffer doing this haha

El Grupo de Usuarios de GNU/Linux de La Laguna celebrará un aniversario más y estaré participando con una conferencia y un taller de OpenStreetMap.

Se efectuará en la Universidad Tecnológica de Torreón el 25 de septiembre desde las 9:00 horas con conferencias y talleres.

La Conferencia

En la conferencia OpenStreetMap: Datos abiertos y más se enseñará al público asistente qué es OpenStreetMap (OSM), qué son los datos abiertos y cómo y por qué usar ambos ya sea en nuestros trabajos, en nuestra comunidad y, principalmente, en nuestra vida diaria.

El Taller de mapeo

En el taller Mapeando mi entorno se enseñará al público asistente a usar OpenStreetMap (OSM) para que puedan agregar a un mapa libre elementos que pueden enriquecer el mapa para todos quienes lo usamos.

Espero que todas las personas que conozcan y les interese el Software Libre nos puedan acompañar el 25 de septiembre desde las 9:00 horas.

Recuerden: 😃🐧 ¡La entrada es Libre, solo tienen que registarse aquí! 😃🐧

最近大阪市鶴見区内をマッピングしていますが、大体の建物の造形が実際と違ったり更地になってたり。近々修正などを始めるかな〜とか思ってのんびりしていますが、先に登録できそうな表示版だったり店舗などが全く進んでいなかったりと時間とやる気不足気味のためある程度の網羅はまだまだ先になりそうかもしれません。

そして関係ないですが最近鼻水が止まりません。ティッシュが足りない…。 もう一つどうでもいいことですが どうやってもこれ開くとGPUプロセスが飛ぶのですが…開ける方いませんか?

Hi everyone! I have been trying to edit some locations but the changeset size is exceeded (cause i forgot to upload after moving to the other country). I have no idea which nodes are from Portugal and which from Italy. Can someone help?

Thank you so much in advance

انتظر بفارغ الصبر مزامنة مابس مي مع osm لان مابس مي من البرامج الأكثر استخدام في منطقتي بالعلم اني استخدم اورجانيك وكومباس ايضاً لأني أحب الخريطه اشكر الجميع اتمنى الخير لكل المجتمع في osm

بيت

got out of the house for a bit today and got started adding/removing some businesses on thames street south, and adding info like hours and contacts to ones that were already there. headed home when it started raining but i feel like i got a pretty good amount done for one walk.

i only really focused on one side of the street to start, i was gonna do the other side on the way home but due to the rain ive just left it for another time. here’s to better weather this week 💜💜

Обеспечение загородного участка автономным водоснабжением — первоочередная задача для любого землевладельца. Традиционно для решения этой проблемы применяется крупногабаритная буровая техника на базе грузовых автомобилей (ЗиЛ, УРАЛ, КамАЗ). Однако на практике буровые бригады часто сталкиваются с объективными препятствиями: плотная застройка, наличие ухоженных газонов, проложенные подземные коммуникации, узкие ворота или линии электропередач, исключающие возможность подъезда и разворота тяжелых машин.

В таких условиях оптимальным выходом становится использование малогабаритных буровых установок (МГБУ). Они позволяют проводить работы в стесненных условиях без ущерба для окружающего ландшафта. При этом гидрогеологические условия Александровского района Владимирской области отличаются крайней неоднородностью и сложностью разреза. Из-за этого применение малых технических средств возможно далеко не везде. Перед началом работ важно детально изучить специфику местных грунтов и водоносных слоев.

Важное примечание: Все приведенные ниже цифровые показатели глубин залегания водоносных горизонтов носят ориентировочный и обобщенный характер. Для получения точной информации и составления достоверного прогноза необходимо консультироваться со специалистами по каждому конкретному адресу.

Виды малогабаритной буровой техники

Современный рынок МГБУ предлагает несколько модификаций оборудования, каждая из которых имеет свои технические ограничения, габариты и область эффективного применения:

Разборные буровые установки

Представляют собой модульные металлические конструкции (переносные рамы), которые собираются непосредственно на точке бурения. Область применения: Бурение неглубоких скважин на песок (включая абиссинские колодцы) в самых труднодоступных местах, подвалах зданий или закрытых павильонах.

Ширина подъездных путей: Специальные пути не требуются. Элементы конструкции переносятся вручную через стандартные калитки шириной от 0,8 метра.

Габариты рабочей площадки: Минимальное пространство составляет около 2х2 метра при высоте потолка/навеса не менее 2,5–3 метров.

Буровые станки малогабаритные на колесном ходу

Компактные установки, смонтированные на базе прицепов для легковых автомобилей или самоходных колесных шасси.

Область применения: Сооружение скважин на мелкий и глубокий песок, а также на ближние известняковые горизонты в условиях обжитых дачных поселков.

Ширина подъездных путей: Для проезда требуется коридор шириной не менее 1,2–1,5 метров.

Габариты рабочей площадки: Для безопасного развертывания мачты и размещения сопутствующего оборудования необходима площадка размером от 3х4 метра.

Буровые малые станки на гусеничном ходу

Самоходные мини-установки на резиновом или металлическом гусеничном ходу, обладающие повышенной проходимостью и мощностью. Область применения: Бурение глубоких эксплуатационных скважин на межпластовые воды (включая известняк) на участках со сложным рельефом или мягким грунтом. Резиновые гусеницы минимизируют повреждение верхнего слоя почвы.

Ширина подъездных путей: Требуется проезд шириной от 1,5 до 1,8 метров. Габариты рабочей площадки: Оптимальная рабочая зона составляет около 4х5 метров с учетом места для бурового раствора и инструмента.

Гидрогеологические особенности Каринского сельского поселения

Каринское сельское поселение характеризуется относительно благоприятными условиями для малогабаритного бурения. Геологический разрез здесь в основном представлен четвертичными отложениями, в которых широкое распространение имеют флювиогляциальные и аллювиальные пески московского и днепровского горизонтов.

На данной территории с высокой степенью вероятности можно оборудовать классические фильтровые скважины на песок под погружной насос. Местами встречаются обильные песчаные линзы с высоким уровнем залегания подземных вод, что позволяет обустраивать так называемые абиссинские иглы (забивные колодцы). В этих слоях формируются безнапорные грунтовые воды, доступные для легкого инструмента.

Тем не менее ключевым фактором успеха выступает геоморфология. Необходимо обязательно учитывать абсолютные высоты над уровнем моря. На возвышенностях и водораздельных плато глубина залегания обводненных песков существенно увеличивается, а верхние горизонты могут оказаться сухими или содержать лишь сезонную верховодку. В таких высоких точках вероятность успешного применения легких разборных МГБУ заметно снижается, и может потребоваться переход на более мощную гусеничную технику.

Гидрогеология Следневского сельского поселения

В Следневском сельском поселении гидрогеологическая обстановка усложняется. Хотя здесь также сохраняется принципиальная возможность бурения малогабаритными установками как под погружной насос, так и под абиссинские скважины, общая вероятность стабильного дебита на малых глубинах чуть ниже, чем в Каринском. Основные запасы чистой воды приурочены к межпластовым водоносным горизонтам, перекрытым сверху толщей моренных суглинков. При планировании работ важно учитывать следующие региональные особенности:

• Зависимость от рельефа. Как и в соседних зонах, отметки высот над уровнем моря диктуют глубину залегания стабильных водных пластов. На локальных возвышенностях маломощная техника может не дойти до обводненной породы.

• Каменистые включения. В ряде населенных пунктов поселения разрезы содержат плотные моренные отложения с обилием валунов, крупных камней и галечника. Прохождение таких интервалов легким инструментом МГБУ часто становится технически невозможным из-за заклинивания бурового снаряда. В подобных зонах эффективно отработать способна исключительно крупногабаритная техника с тяжелым ударно-канатным или мощным роторным инструментом.

• Географический градиент. При приближении к границам Ярославской области гидрогеологические условия закономерно ухудшаются: песчаные водоносы истощаются, замещаются глинистыми фракциями, а глубина залегания коренных водоносных пород растет. В связи с этим шансы на успешное применение малых установок при движении на север и северо-восток Следневского поселения стремительно падают.

Гидрогеологические условия Андреевского сельского поселения

Ситуация в Андреевском сельском поселении во многом дублирует условия Следневского, однако имеет свои специфические черты, требующие обстоятельного рассмотрения. Верхняя часть разреза сложена покровными суглинками и ледниковой мореной. Полноценный водоносный горизонт в четвертичных отложениях здесь носит мозаичный характер. Это означает, что обильные флювиогляциальные пески могут чередоваться с совершенно сухими зонами.

Верховодка в Андреевском поселении крайне нестабильна и сильно зависит от количества осадков, поэтому ориентироваться на нее при создании долговечного источника водоснабжения нельзя. Грунтовые воды часто характеризуются повышенным содержанием соединений железа и органики из-за близкого залегания юрских глинистых водоупоров.

Шансы пробурить надежную песчаную скважину с помощью МГБУ колеблются от средних до низких в зависимости от конкретной деревни. Использование разборных профильных рам оправдано только на пониженных рельефах и в поймах рек. На средних и высоких геодезических отметках бурение на песок часто превращается в разведочное, не приносящее результата. Для гарантированного получения воды приходится ориентироваться на более глубокие межпластовые воды, залегающие под юрскими глинами (в диапазонах, которые могут достигать 50–75 метров и более). Проходка таких глубин по плотным глинам требует от малогабаритной техники высокого крутящего момента и обязательного использования качественных буровых растворов.

Гидрогеологические особенности в Краснопламенском сельском поселении

Краснопламенское сельское поселение признано наиболее сложным сектором Александровского района с точки зрения автономного водоснабжения. Здесь фиксируются самые низкие шансы на успешную эксплуатацию стандартных малогабаритных буровых установок.

Главная причина кроется в специфике геологического строения:

• Глубокие пески. Водоносные песчаные горизонты здесь залегают на значительных глубинах, часто уходя за пределы технических возможностей легких станков.

• Сложные, непредсказуемые разрезы. Мощные толщи плотных моренных суглинков чередуются с валунно-галечниковыми интервалами и сухими мелкозернистыми песками, которые склонны к осыпанию и создают эффект «плывуна». Такие условия требуют постоянного крепления ствола скважины обсадными трубами в процессе проходки.

На территории Краснопламенского поселения использование МГБУ невозможно планировать вслепую или на основе усредненных районных карт. Возможность применения малой техники необходимо проверять индивидуально, с точностью до конкретного адреса в населенном пункте. Даже на соседних участках в пределах одной деревни гидрогеологический разрез может кардинально отличаться.

Полезные советы по бурению малой техникой в Александровском районе

Малогабаритные буровые установки — это эффективный и щадящий инструмент для решения задач водоснабжения, незаменимый в условиях плотной застройки Александровского района. Однако сложная гидрогеология региона, обусловленная ледниковым происхождением местных рельефов, накладывает строгие ограничения на их использование. В то время как в Каринском поселении шансы на успех легкой техники весьма велики, в Следневском и Андреевском они требуют учета каменистых включений и высотных отметок, а в Краснопламенском сводятся к минимуму.

Для получения точного прогноза и исключения финансовых потерь на бесперспективную разведку настоятельно рекомендуется перед началом работ проконсультироваться у нескольких независимых буровых бригад. При обращении обязательно указывайте точные географические координаты или адрес участка. Опытные мастера, регулярно работающие в Александровском районе, смогут трезво оценить реальные технологические лимиты своего оборудования, сопоставить их с архивными данными по соседним скважинам и дать четкий, обоснованный прогноз.
