Why Sony Headphones is More Tempting than Other

Few years back, I owned a dozen pair of headphones (didn't try the Sony yet) and decided to go with the Sennheiser HD380. While they were a little uncomfortable in the first week, they got 'burned in' and became very comfortable and much less clamping. The ear cups are a little too big, the sound is cool, but when you get to feel what it’s like to have a Sony Headphone – everything c

Few years back, I owned a dozen pair of headphones (didn't try the Sony yet) and decided to go with the Sennheiser HD380. While they were a little uncomfortable in the first week, they got 'burned in' and became very comfortable and much less clamping. The ear cups are a little too big, the sound is cool, but when you get to feel what it’s like to have a Sony Headphone – everything change.

Although I love just about everything about the Sennheiser HD380, if I wanted to spend money on a pair of over-ear headphones, the Sony MDR-XB950AP Extra Bass , is the set I would buy. I did my research, read countless professional and Amazon

Typical errors that can be solved with Jochen Topf’s MapRoulette task 1 | (C) OpenStreetMap Contributors CC-BY-SA 2.0

Mapping

  • [1] Jochen Topf has started a Maproulette-Challenge to repair invalid areas in OSM and wrote in his blog about it. Let’s begin with self-overlapping closed ways with tag building=*. More Challenges
  • As part of the “fixing broken multipolygons” discussion, Christoph Hormann suggests that removing forest polygons from the old Corine landcover imports might be a better solution than repairing them, because they are very inaccurate.
  • CloCkWeRX posts on enhancements proposed to OnOsm.org, some of them have already been accepted, for example, the location helper and internationalization, among others.
  • Bryan Housel shows how picnic sites can be mapped easily using the iD editor and multi-selections.
  • User Jojo4u proposes a new feature “meadow orchard” (German: “Streuobstwiese”) which is a meadow with scattered fruit trees or fruit trees that are planted in a field. The proposed tagging is possible with combinations of landuse=meadow or landuse=orchard.
  • On talk-fr, Rogelio brings up the matter of toll fee data into OSM. It’s not clear if having this information in OSM is desirable or even feasible but some options are discussed to ease the integration of toll fee prices for OSM-based routing engines.
  • Martin Koppenhoefer proposes the documentation of the usage of amenity=luggage_locker and amenity=locker tags. This initiates a discussion on the need for two different tags for a seemingly similar utility.
  • The usage of amenity=vending_machine tag was discussed at length on the Tagging mailing list including what is within the scope of the term ‘vending’ and what are the alternatives to the amenities tag.
  • Joost Schouppe writes about evaluating completion of the road map network in Flanders, Belgium. A thorough analysis is made along with many graphs and time-lapse animations.
  • User Marczoutendijk wrote an article about the tagging of restaurants and its particularities in OSM. Bon appetit!
  • The Mapbox Data Team invites you to map points of interest in San Francisco using JOSM with the Mapillary plugin. A comprehensive guide is provided and the project is open on the Mapbox tasking manager.

Community

  • JOSM maintainer Dirk Stöcker is concerned about the increasing gap between the translations. He is told that the launchpad translation platform is the problem.
  • Steve Coast showcases his OSM Stats website where the evolution of the various types of ways can be gathered by country. Direct links to: UK and US.

Imports

  • Facebook are suggesting that they try again with their “AI-based” road detection. Last time it didn’t work so well. Last time, imports in Egypt and Thailand were reverted because they were “far more wrong than right” (draining ditches being added as “roads”, among other things). Apparently this time they are now working with a larger team of highly-trained mappers and have added steps to the validation process.
  • Nick Bolten, of the projects OpenSidewalks and AccessMap, announced a test import of footpaths in Seattle (Washington state). There were already extensive discussions on the mailing lists tagging and Imports.
  • Max Bainrot suggests to use the ACTmapi data from Australia for OpenStreetMap. The data is under CC-BY, but there is probably a special permission for OpenStreetMap.

Events

  • The submission of talk proposals for the 2017 State of the Map in Aizu-Wakamatsu, Japan is open until April 2nd.

Humanitarian OSM

  • Mikel Maron reports that Mapbox has matched a US$ 10,000 grant to the HOT Microgrants Program (which we reported earlier).
  • User MangleBlanco writes about impressive geological history of the Southernmost tip of the Caribbean Sea and why open source data might be key to sustainable development in the region. He also pledges to provide high resolution data for mapping efforts and humanitarian projects in the area.
  • It seems that Fred Moine is not quite convinced by the quality of the mapping in Haiti by HOT volunteers.

Maps

  • The OSM website now has a new right-click context menu which was programmed by user mcld. You can now set directions to and from points, centre the map, add notes, etc. The item “show tile image”, which was available in the previous browser-default image context menu, is missing. Ilya Zverev proposed to add it, but his pull request was denied – a long list of comments criticizing Tom followed.
  • Mapzen added a new feature to the Who’s On First Spelunker: the Bundler. Now, after you selected a place, downloading a GeoJSON blob containing all its descendants with selectable categories is a few clicks away!

Open Data

  • Do you already know the Open Digital Elevation Model – “The Portal for sharing the 3rd dimension”? At the beginning of the year, North Rhine-Westphalia (DE), Belgium, New Zealand and Switzerland joined.
  • Open data under Trump probably doesn’t exist any more. The White House’s Open Data Portal has been emptied, user @denormalize reported on Twitter.

Licences

  • KSJ2 data in Japan must not be imported any more because the terms of use have been changed (source).

Software

  • An introduction tutorial for QGIS Atlas, a QGIS feature (formerly a plug-in) that allows you to create map snippets around a collection of features (eg a POI shape file).
  • Ilya Zverev announced a new import tool. The OSM Conflator checks for matching objects in the OSM data. It adds tags to existing objects or creates new nodes for unmatched points.
  • Martin Ždila announced his Toposcope Maker. Toposcopes can be found on top of hills or high places which indicates the direction to notable landscape features or cities.

Programming

  • Frederik Ramm (woodpeck) submitted a pull request which would allow the geometry of deleted OSM objects to be displayed on “browse” pages. It was rejected for various technical reasons – see this comment by Matt and the comments above for a summary.
  • Geofabrik announces that the download server now has full history files for all regions served. These files (called “.osh.pbf”) can be used to run analyses, and one can use Osmium to convert them to a text-based format (“OPL”) that is then accessible for grep et al.

Releases

Software Version Release date Comment

Did you know …

  • …the historic maps of Berlin? Here you can see them as an adjustable transparent layer on top of OSM.

OSM in the media

  • An article (automatic translation) in Swiss media talks about three map services to navigate in Switzerland, which offer more accuracy than Google Maps. Guess what? OpenStreetMap is one of them.

Other “geo” things

  • A podcast from BBC Radio 3 in the UK, is available worldwide, handling contents about the UK and Germany. The podcast has no OSM content, but it discusses in general and particular what borders mean to people.
  • An article (de)discusses the App “Metro” which provides routing through the public transportations network in Havana, Cuba.
  • A single Indian rocket launched 104 satellites into space, including 88 micro satellites for Earth observation of the US start-up Planet.
  • Ever wondered how each of the US states would compare to an European area with similar population? Wonder no more!. And how about European countries over the American continent? Speech500 has you covered too.
  • The xkcd webcomic strip shows us how the world would look like if we were to correct every country’s layout by their timezones.

Adding unknown roads using ImproveOSM

When using ImproveOSM, the Telenav tool to find and add missing roads (and other missing things) in OSM, sometimes there is just no detailed aerial imagery to see exactly what road type it is.

When using ImproveOSM, the Telenav tool to find and add missing roads (and other missing things) in OSM, sometimes there is just no detailed aerial imagery to see exactly what road type it is.

example

While you could say, 'Well without being able to see, I won't add anything'. But because ImproveOSM uses actual GPS traces from drivers, you know that people have been driving there. From the image in the example you can see that a fair number of people must have taken this route, so there must be some sort of road there.

So what I suggest is to add the road as simply highway=road (generic road tag). Then you or someone else can improve it later, based on better imagery or local knowledge.

The example in the image is this new way.

Remember that you can select multiple tiles on ImproveOSM by holding Shift while selecting. That way you can more quickly mark multiple tiles as Solved.

Motive.io + Mapbox Unity SDK

Motive.io, a platform for building location-based games, just launched with the latest version of the Mapbox Unity SDK. Here is how I used it to quickly create an augmented reality “Ghost Hunter” game.

Motive.io, a platform for building location-based games, just launched with the latest version of the Mapbox Unity SDK. Here is how I used it to quickly create an augmented reality “Ghost Hunter” game.

To get started, I began by creating a base map in Mapbox Studio and styled it to match the exact look and feel of my game.

mapbox-editor Styling the base map in Mapbox Studio.

Next, I used the Motive.io authoring tool to generate a catalog of items like batteries, food, hammers, and wood for game players to collect from real-world locations to hunt ghosts that are menacing their city.

screenshot-ingredients Author in-game content like collectibles, characters, media, and more using Motive.io’s web-based authoring tool. Content is downloaded to your game on demand, which means you can add and tweak content even after release.

After I created my catalog, I assigned these items to real-world places using the Motive.io script editor. Using Motive.io and Mapbox’s location data, you can assign items to different types of locations (like restaurants or parks) along with a probability for how often the items will spawn in those places.

screenshot-scripts Motive.io’s script authoring tool lets you program complex gameplay with a simple drag-and-drop interface. Like all other game content, scripts are downloaded on demand.

I then followed a similar procedure to place ghosts in the game world that players hunt in the real-world. The Motive.io script authoring tool gives you control over where, when, and how the characters are placed. For instance, I could have a particular over-caffeinated ghoul appear only at coffee shops on rainy Tuesday afternoons, and due to Mapbox’s global location data, this works anywhere in the world.

Now, let’s run the game and see what we get! The Motive.io engine and server automatically sync with Mapbox map data and infrastructure so you get the latest game content at runtime. The Unity template that you create with Motive.io gives you controls and annotations out of the box.

screenshot-editor Motive.io’s Unity templates make it easy to quicky create a game environment.

That’s it! In just a few clicks I created a location-based Ghost Hunter game! Check out Motive.io for more information, and stay tuned for some big announcements from them coming up at GDC 2017!

Going to GDC? Stop by Mapbox’s booth, #2330 in the South Hall Expo, to check out live mobile demos and walk through the code of the Mapbox Unity SDK. In the meantime make sure to download the SDK here.

Fixing broken riverbanks

Stumbled upon a dried up Nile on the map, which seems to be a jumble of large multipolygons.

This might require the expertise of an expert with the JOSM relation editor which can be a time consuming process.

It would be great if someone could make a simple howto tutorial for fixing such scenarios to help fix so many other big rivers that are broken this way.

Static API with overlays

As of today, you can add custom overlays to your static maps when making requests to the Static API. This is useful in situations where JavaScript is not available or if you’re trying to keep your UI light. Take for example a ride sharing app that sends a receipt to the user. In the receipt email they can show the route, pickup location, and dropoff location all with a single Static API request.

Mapbox Static API with encoded polyline path

Ride sharing receipt example. View request.

The Static API allows for 4 different types of overlays: GeoJSON styled with the simplestyle-spec, Maki marker, custom marker, or an encoded polyline. A single request can have a combination of overlay types and allows up to 100 features.

Since this is Mapbox GL under the hood, it’s possible to change where the overlay ends up in the style’s layer hierarchy. By specifying the query parameter before_layer, the overlays will be inserted before the specified layer in the style. This is great for putting data under labels.

Deep digital mapping

Last weekend I went to map an archaeological site. I had read a couple of academic archeological papers on this excavation and knew the exact location of the site.

It is a Roman tiles, bricks and ceramic workshop near the town of Chancy which worked for eight hundred years, from 1st century BC till 7th century AD.

Last weekend I went to map an archaeological site. I had read a couple of academic archeological papers on this excavation and knew the exact location of the site.

It is a Roman tiles, bricks and ceramic workshop near the town of Chancy which worked for eight hundred years, from 1st century BC till 7th century AD.

This archaeological site was excavated, and then it was covered with earth again for preservation. Still there are antique tiles everywhere around. At that epoch it was a hi-tech enterprise, a place where the Roman Empire was actually built. And it is not completely clear why it was closed after eight centuries of production (an interesting question for today's reality too).

As a result:

I convert video to the open WEBM format, which is accepted by Wikimedia, with the command line tool ffmpeg. Some quality is always lost in conversion, but so far it is the best variant:

ffmpeg -i source.mp4 -c:v libvpx -crf 4 -b:v 18M -c:a libvorbis destination.webm

I used a free music with Creative Commons license for the video. But it is also possible to play yourself and record any music of any composer who died more than 70 years ago. For example, for these two videos I asked my spouse to play and record the musical themes:

Battle of Morgarten

The town of Zug

The idea of deep digital mapping is that reaching a remote destination takes time and effort. So being physically at the location allows not only to map an object on the OSM map, but also to film it, to record first hand impressions, perhaps to do some investigative journalism for a Wikipedia article, and link all this to the OSM map.

I realize by now that recording and editing a video is even more difficult than making good photos. Recording a musical theme is a world in itself too. It turns out that a digital piano does not record a MP3 file, but MIDI file (musical instrument digital interface), which should be exported to a computer first and then converted to an audio file with a program like the Logic Pro X.

If you have ideas or information on developing deep digital mapping, please, let me know.

    Typische Fehler, die mit der MapRoulette Aufgabe von Jochen Topf beseitigt werden können 1 | (C) OpenStreetMap Mitwirkende CC-BY-SA 2.0

Mapping

  • [1] Jochen Topf hat eine Maproulette-Challenge zur Reparatur invalider Flächen in OSM gestartet und schreibt in seinem Blog darüber. Los ging es mit sich selbst überschneidenden geschlossenen Ways mit building=*. Die Challenge war recht schnell erledigt, aber Jochen hat weitere Challenges auf Lager.

  • Christoph Hormann schlägt auf der Mailingliste Talk vor, dass man die kaputten Wald-Multipolygone des Corine Landcover Imports löschen und durch neu gezeichnete Objekte ersetzen solle, da sie sehr ungenau sind.

  • CloCkWeRx schreibt über die Erweiterungen, die er für OnOsm.org programmiert hat. Viele davon wurden bereits akzeptiert und eingebunden.

  • iD-Entwickler Bryan Housel zeigt im Mapbox-Blog das Mappen von Picknicktischen und die Mehrfachauswahlfunktion des iD-Editors.

  • User Jojo4u greift ein Proposal von 2015 zum genaueren Tagging von Streuobstwiesen wieder auf und stößt damit eine lebhafte Diskussion im Forum an.

  • Rogelio Canedo schlägt (fr) (automatische Übersetzung) auf der Mailingliste Talk-fr Relationen zum Mapping von Mautgebühren vor.

  • Martin Koppenhoefer bittet um Kommentare zu zwei Tagging-Proposals, die die schon gebräuchliche Verwendung von amenity=locker für Bankschließfächer und amenity=luggage_locker für Gepäckschließfächer dokumentieren.

  • Auf der Mailingliste tagging wurde sehr ausführlich über amenity=vending_machine diskutiert. Vor allem darüber, was alles unter den breiten Begriff „Verkauf“ fällt.

  • Joost Schouppe schreibt in seinem Benutzer-Blog über das Längenwachstum des OSM-Wegenetz in Flandern.

  • Mahlzeit! User marczoutendijk hinterfragt in seinem Benutzer-Blog die Logik(-schwächen) unseres Restaurant-Taggings.

Community

  • JOSM-Maintainer Dirk Stöcker beklagt auf der Mailingliste JOSM-dev die zunehmenden Lücken in den Übersetzungen von JOSM. Ihm wird entgegnet, dass die Übersetzungsplattform Launchpad das Problem sei.

  • Andreas Kunze sucht im OSM-Forum Hilfe, da er das gemeinsame Forschungsprojekt über die Pilzvorkommen in Bayern, Tschechien und Österreich mit einer Karte visualisieren will.

  • Steve Coast präsentiert seine OSM-Statistiken, welche den Zuwachs verschiedener Straßen- und Weg-Typen über die Zeit und je Land darstellen. (AT, CH, DE).

  • Die Essener Gruppe von „Code for Ruhrgebiet“ möchte mit OpenStreetMap-Daten arbeiten und sucht für das nächste Treffen am 5. März Unterstützung aus dem OSM-Umfeld.

Importe

  • Facebook startet einen zweiten Anlauf, aus Satellitenbildern automatisch erkannte Straßen in OSM hochzuladen. Der erste Anlauf in Ägypten und Thailand war nicht sonderlich erfolgreich und wurde daher revertiert. Scheinbar versucht es Facebook dieses mal mit einem erheblich größeren Team von hochqualifizierten Mappern und weiteren Schritten für einen Validierungsprozess. (Update: Links + Zusatzinformation ergänzt)

  • Nick Bolten von den Projekten OpenSidewalks und AccessMap kündigt einen Testimport von Fußwegen in Seattle (US-Bundesstaat Washington) an. Dazu gab es letzten Sommer schon ausführliche Diskussionen auf den Mailinglisten Tagging und Imports.

  • Max Bainrot schlägt vor, die ACTmapi-Daten aus Australien für OpenStreetMap zu verwenden. Die Daten stehen zwar unter CC-BY, es gibt aber wohl eine spezielle Genehmigung für OpenStreetMap.

Veranstaltungen

  • Für die State of the Map 2017 in Aizuwakamatsu (Japan) können bis zum 2. April Vorträge, Lightning Talks und Workshops eingereicht werden, wie der Blog der OSMF berichtet.

Humanitarian OSM

  • Mikel Maron berichtet im Mapbox-Blog über eine Spende in Höhe von 10.000 US$ an das HOT-Microgrants-Program (wir berichteten). Ein Video zeigt, um was es geht.

  • MangleBlanco schreibt über die beeindruckende geologische Geschichte des Karibischen Meers und bietet hoch auflösende Bilder zum Mappen für humanitäre Projekte in der Gegend an.

  • Fred Moine stört sich stark an der schlechten Mappingqualität in Haiti durch HOT-Freiwillige.

Karten

  • Die Karte der OSM-Hauptseite verfügt jetzt über ein Kontextmenü, welches per Rechtsklick erreichbar ist. In diesem vom Benutzer mcld initierten Menü kann man Start- und End-Punkte einer Route festlegen, die Karte zentrieren oder Notizen hinzufügen. Das vorher vorhandene Kontextmenü, welches Browser standardmäßig auf Bildern anzeigen, ist entfernt worden. Der von einigen Benutzern genutzte Menüpunkt „Grafik anzeigen“ fehlt auch. Ilya Zverev versuchte, ihn in das neue Menü einzubauen. Seine Pull-Request wurde aber abgelehnt, was mehrere Leute kritisieren.

  • Mapzen veröffentlicht ein Tool, welches mit einem Klick bspw. das Herunterladen von allen Kreisen eines Bundeslandes als GeoJSON ermöglicht. Der „Bundler“ genannte Service ist Teil von „Who’s On First Spelunker“.

Open-Data

  • Die Luftbilder der Stadt Mainz sind für OSM zum Erfassen freigegeben worden, wie Joachim Kast mitteilt. Einzelne Mitarbeiter der Stadt dürfen zudem auf interne Unterlagen zugreifen, um in Neubaugebieten neue Gebäude einzutragen.

  • Kennst du schon das Open Digital Elevation Model „The Portal for sharing the 3rd Dimension“? Zum Jahresbeginn sind Nordrhein-Westfalen (DE), Belgien, Neuseeland und die Schweiz hinzugekommen.

  • ubahnverleih hat aus den Postleitzahlpolygonen von OSM und dem Verwaltungsgrenzen-Datensatz des Bundesamt für Kartographie und Geodäsie eine CSV-Datei (Download) mit der Zuordnung Postleitzahl → Landkreis erstellt. (Quelle: Twitter)

  • Open Data gibt’s unter Trump wohl nicht. Das Open-Data-Portal des Weißen Hauses ist geleert worden, wie Benutzer denormalize auf Twitter berichtet.

Lizenzen

  • KSJ2-Daten in Japan dürfen nicht mehr länger importiert werden, da sich die Nutzungsbedingungen geändert haben.

Programme

  • Ein Einführungstutorial für QGIS Atlas, eine QGIS-Funktion (vormals Plugin), mit der man Kartenausschnitte rund um eine Sammlung an Features (z.B. ein POI-Shapefile) exportieren kann.

  • Ilya Zverev stellt als ein neues Import-Werkzeug den OSM Conflator vor. Eine Liste von POIs wird darauf überprüft, ob sie schon in der OSM-Datenbank vorhanden sind. Je nach Ergebnis werden die Daten ergänzt oder neue Knoten erstellt.

  • Martin Ždila stellt auf der Mailingliste Talk seinen Toposcope Maker vor. Damit lassen sich anhand einer OSM-Karte Panoramatafeln erstellen, wie man sie oft auf Aussichtspunkten findet.

Programmierung

  • Ein Pull-Request von Frederik Ramm (woodpeck), der die Geometrie gelöschter Wege hätte anzeigen sollen, wurde aus verschiedenen Gründen abgelehnt.

  • Die Geofabrik bietet auf ihrem Download-Server künftig auch wöchentlich aktualisierte Extrakte des Full-History-Planets an – ein Ergebnis des OSM-Hackweekends in Karlsruhe am vergangenen Wochenende.

Releases

Kennst du schon …

  • … die historischen Karten von Berlin? Hier kannst du sie dir als transparenten Layer über einer OSM-Karte anzeigen lassen.

OSM in der Presse

  • Der Schweizer Tages-Anzeiger untersucht mehrere Alternativen zum großen G und ist insbesondere von der Qualität OSM-basierter Dienste begeistert.

Weitere Themen mit Geo-Bezug

  • Ein Podcast von BBC Radio 3 (45 Minuten, englisch, braucht Flash) beschäftigt sich mit den Bedeutungen geographischer Grenzen.

  • Gunda Wienke von der amerika21-Redaktion berichtet von der Transport-App „Metro“, von Eduardo Sánchez entwickelt. Diese auf OSM basierende App zeigt Karten der Metro- und Taxi-Standorte in Havanna (Kuba).

  • Eine indische Rakete hat 104 Satelliten auf einmal ins All befördert, darunter 88 Mikrosatelliten zur Erdbeobachtung des US-Startups Planet.

  • Speech500 hat zwei Karten erstellt, die die Länder in Europa und die US-Staaten je auf Gebiete mit gleichen Bevölkerungszahlen des jeweils anderen Kontinents überlagern.

Improved ski ressorts rendering

OpenSnowMap.org renders ski ressorts at zoom 10,11 & 12. For this, it takes either site=piste relations or landuse=winter_sports polygons, and checks what type of pistes they contain (downhill, nordic, sled, etc...) in order to display small icons next to the ressort name.

Until now, these icons where pre-calculated images of all possible combinations.They were not so nice, and did no

OpenSnowMap.org renders ski ressorts at zoom 10,11 & 12. For this, it takes either site=piste relations or landuse=winter_sports polygons, and checks what type of pistes they contain (downhill, nordic, sled, etc...) in order to display small icons next to the ressort name.

Until now, these icons where pre-calculated images of all possible combinations.They were not so nice, and did not scale well with the big tiles used on the mobile site. So I built a very handy font file, called Ski.ttf, that looks like this:

Skki_TTF.png

This allows me to use Mapnik list-placement on TextSymbolizers to position the needed icons nicely.

It will takes some time for the tiles to re-render, so here what it looks like:

Describing Wikidata items with OpenStreetMap tags

For the curious, the crowdsourced open knowledge database - Wikidata has a property for OpenStreetMap tags that can be used to tag items that describe the same/similar object on the Wikidata database.

It took some time to understand how Wikidata items are described having been used to the more flat OSM tagging model, but we can use a simple example of the popular OSM tag of that is use

For the curious, the crowdsourced open knowledge database - Wikidata has a property for OpenStreetMap tags that can be used to tag items that describe the same/similar object on the Wikidata database.

It took some time to understand how Wikidata items are described having been used to the more flat OSM tagging model, but we can use a simple example of the popular OSM tag of that is used for any human settlement as a start.

Finding a Wikidata item describing an OSM tag

Any notable topic that exists on Wikipedia will exist as a Wikidata item. Hence any widely used OSM tag should be easy to match to a Wikidata item. For example, cities are one of the most important features of maps, and from the OSM Wiki we know that this feature is described on the map using the Tag:place=city.

If we can find a Wikipedia page that describes the same concept as the OSM tag, we can get the associated Wikidata item from the sidebar links of the page. The Wikidata item for a city is Q515.

Improving Wikidata using OpenStreetMap tags

We can associate the city item Q515 on Wikidata to the OSM tag place=city by adding it as a new property to the item.

new3 Add Tag:place=city as a new OpenStreetMap tag or key property to the item

This will create a link on the Q515 item to the OSM Wiki Tag:place=city page.

Querying Wikidata using OpenStreetMap tags

By adding OSM tags to Wikidata, it is now possible to query Wikidata for all items that are linked to this property.

The query runs live on the Wikidata database using a language called SPARQL, similar to OverpassQL for OpenStreetMap.

Note The above queries only list items that are a direct instance of (P31) a city or town item in Wikidata. Unlike OSM, these items in Wikidata can have a fairly large structure of children items that more specifically describe a type of city. In the future I'm looking to further explore how we can use OSM and WIkidata together for data validation across both projects.

Update The total number of Wikidata items with an OSM tag is currently 964 items - Thanks to Ainali on #wikidata for the query

Uploaded three tracks , my first ever , please let me know what could have been done better

As it says in the Subject line : have looked at a number of points raised near where I live, found one blocked street (Berkenlaan Antwerpen / Wilrijk) was not blocked , and no signs of roadworks or similar. Have added comment.

Question 1 : can I, as a novice contributor, declare the item as resolved, or are there trained and trusted resolvers, please?

Proceeded to the re-routed

As it says in the Subject line : have looked at a number of points raised near where I live, found one blocked street (Berkenlaan Antwerpen / Wilrijk) was not blocked , and no signs of roadworks or similar. Have added comment.

Question 1 : can I, as a novice contributor, declare the item as resolved, or are there trained and trusted resolvers, please?

Proceeded to the re-routed bicycle path / access road at the eastern end of the Antwerp/ Deurne airport runway, uploaded three tracks showing the connection road between a/ the decommissionned Fort 3 and the Beirenslaan, b/ the U-turn road with separate adjacent bicycle path, and c/ the bit connectin these two to allow traffic from the east to reach Fort 3 etc.

Question 2 : those tags : are these relevant as entered, which ones would experienced OSmappers have added, which ones would they have left out?

Next, visited recent parkland 'Groot Schijn' at the end of the Veldweg : found some concrete walking/ bicycling paths were not on the map, made tracks and will upload once initial comments received on first uploads.

Along Ruggeveldlaan one 'doorsteek' / U-turn passage doesn't exist anymore ; track of new traffic light regulated pedestrian / cyclist crossing to be uploaded.

Further along Ruggeveldlaan : one building demolished (will add note on map), one access road moved.

Question 3 : how can upload the waypoint saved at the new entrance road, please? As a single point track?

Have taken photos w. Lumia smartphone, they're on OneDrive, need to find out how to publish map with only photos pertaining to OpenStreetMap, excluding private ones.

Finallt visited end of Parkweg, where there is a query about section of road removed, which is correct : there's a new parking area. Will add comment and/ or resolve once I know whether that's up to me to do.

Looking forward to comments,

To an editor user for osm edits , I would definitely find nothing more comfortable that it. However, with my recent exposure to josm and all its abilities, life has been greatly simplified. It is embedded with a number of tools, more to it very simplified shortcuts to making viable edits, more to it is the minimal internet consumption hence a multi million edits can be performed in a blink of an eye. The ability of it being installed without cracks makes it much ore suitable. Thanks to josm because editing is now becoming an addiction.
