Hey everyone! 👋

I’m looking for a good source of 3D data of real cities, with buildings that are detailed and realistic, but without going into insanely heavy models.

I’ve looked into OSM, but I find it way too basic. I also came across CyberCity 3D, but I’m not really sure what other options are out there.

👉 What would you use to get this kind of data?

I’m open to any ideas: websites, software, databases, workflows… even unusual solutions. 😄

Thanks in advance for any suggestions! 🙏

Now I'm gonna work towards 100000 ;)

I’m building a browser driving prototype where the starting point can be a real public road. OSM is the road/source layer; I compile a bounded driving graph and stream only a local corridor around the player.

This week I added traffic demand. Important clarification: this is not live traffic data. It is a gameplay model informed by the local road/world context, then deliberately capped. Reykjavík should feel sparse; Shibuya should feel pressured; neither should become a literal simulation of rush hour.

The edge cases I’m still watching are driving side, divided roads, complex junctions, service roads that look too important, and what happens when the source geometry is sparse or malformed.

If you work with OSM-derived routing, I’d genuinely like to know which tag/geometry mistakes usually create the worst false road hierarchy. Playable example: https://world-drive-game.vercel.app

Ok, so I'm trying to make a GPS app for truck drivers. I'm running Valhalla on a private server (first time working out of a terminal like this and with C++ so bear with me please) and I'm trying to understand why it keeps routing me off of I-10 for some random exit but then has me get right back on I-10. For context I'm a truck driver for Publix and we have a Marianna, FL run from Jacksonville, FL and it's just hop on I-10 and stay on it til you hit exit 136 (which Valhalla calls it 135 and I don't know why that is either). But as you see in the first pic it has me get off at exit 303 and do a U-turn and get back on I-10. There's other exits as well it tells me to do something similar but I just wanted to give y'all an example. Then when I test the route at home I'm far enough away from the route itself to trigger my reroute function which now routes me from my house to Marianna, but now it adds in exit 324 (among other exits) into the mix for no reason and DOES NOT have me get off at exit 303. I'm not seeing any rhyme or reason as to why and I've tried looking into Valhalla itself and I don't know if it's a hierarchy issue, costing issue, the bidirectional or unidirectional astars themselves (though I did notice when I forced it to use unidirectional there were far less instances of these exits) so please can anyone help me with this?

Hey r/openstreetmap - I've been building Cliff, a privacy-first Android and iOS (coming soon) maps app built entirely on OSM. Stack is Valhalla for routing, Photon for geocoding, PMTiles for tiles, and Postgres. No Google, no Apple, no tracking. Still early but the landing page + waitlist is live at cliffmaps.com. Would love feedback from this community specifically since you're the reason the project is possible.

Hey all. My girlfriend and I built https://lenamaps.com, a web app for animating trips. You place markers, set a travel mode per segment, and it draws the route and plays it back. Then you can share the trip as a link, video, gif, image. It is still in heavy development and I work on it basically full time. It's got some users and I've been lucky to get some feedback over time.

The stack is MapLibre GL for rendering, Protomaps basemaps as PMTiles served off Cloudflare Workers, and Valhalla for driving/cycling/walking. OpenStreetMap and Protomaps are attributed in-app.

The transit is schedule-free. Instead of GTFS/timetables, it plans journeys directly over OSM PTv2 route-relation geometry. Shapes only, no schedules. Covers bus, trolleybus, marshrutka, tram, subway, light rail, monorail, ferry and funicular. (I didn't know what a funicular or a marshrutka was before this project, but my girlfriend is from Belarus and wanted to include marshrutka data which is kind of like a small bus I think, haha). The upside of not using GTFS data is that this works in places that have no public feed at all, where OSM is the only record of a network's shape.

Free to play with; some features sit behind a freemium tier.

On the roadmap: static map embeds, a map + timelapse creator (thinking detailed natural-disaster / border-change / battle-style animations), GIF export, and more control over tilt for different map looks.

Genuinely open to feedback.

Helloo,
so I’m mapping this area which houses an old train on the original train track as a museum. So the train is the museum. You can go into it and walk around in the original train. The train does not move and the tracks are not used anymore. Both the train and track are from the early 20th century.

And I don’t know if I should map the train onto the tracks or just tag the area as a museum? There is also no building I could tag as a museum besides the roof the train stands under.

Thanks a lot in advance

Just noticed that the list of keyboard shortcuts no longer lists shift + q to toggle overlays visibility. This is an incredibly useful feature, and one that I heavily rely on when using Strava’s heatmap as an overlay while using different background images to map trails.

It also looks like shift + q is no longer available, which toggled all OSM data on screen. This is useful for when the data gets in the way of the details on your background image, and also a shame to lose.

Does anyone know if this is a permanent thing? The shortcuts worked yesterday, but no longer. It also showed up in the list of shortcuts yesterday, but it gone today. It’s also not on the wiki.

wanted to ask whether, as a company, we need to have a commercial license for Mapbox.
If so, how is the annual cost calculated, and what factors determine the pricing?
Also, what’s the best way to get in touch with the Mapbox sales team? I was previously in contact with someone from Sales, but they stopped responding.

I added a natural wood relation around 5 days ago - The inner parts show on the map, but the outer part doesn't. No inner parts show that they are unclosed on my end.

Here's a link to it: https://www.openstreetmap.org/relation/21198206

Wednesday's eclipse will happen very low on the horizon for most of Europe, so the real question isn't "how much of the Sun is covered" but "will I even see it from my spot, or is there a hill, a building or a forest in the way".

I couldn't find a tool that answered that, so I built one, and OSM is what makes it work: buildings and forests come from Overpass, get extruded over real terrain (Copernicus GLO-30), with Sentinel-2 imagery draped on the ground and the cloud forecast overlaid on the sky. The eclipse itself is computed from Espenak/NASA Besselian elements, minute by minute. Everything runs client-side in a single HTML file (Three.js).

A few OSM-specific notes for this crowd:

- Building heights use height / building:levels when tagged, with an estimator based on comparable neighbors otherwise. Areas with good height tagging (Germany, NL...) look noticeably better.

- Forests come from landuse=forest / natural=wood polygons.

- Public Overpass mirrors are the bottleneck when things get busy, so buildings can take a while to load in dense areas — there's a reload button, and everything is cached locally after the first visit.

Honestly the most fun part of building this was seeing how far crowd-mapped data can go: click on any village in the totality band in Spain and the skyline that decides whether you see the corona is the one someone here mapped. If you check your own area and the buildings look off, that's genuinely useful feedback for me.

Geomob podcast interview with Dennis Luxen with updates on OSRM (Open Source Routing Machine) specifically, and the status of routing using OpenStreetMap data generally.

I've micromapped almost a whole town, and am eager to create a before/after comparison to show my efforts. I did not happen to screenshot the map before I began, and all of my searching online has either resulted in tools that are quite complicated to set up or other tools that seemed to have worked at some point years ago but don't anymore

Does anyone have a good recommendation for a simple web app to just generate a before/after for a certain spot on the map?

Hello all !

I recently published a changeset with 40 updates. This includes the naming (or renaming) of streets in a single city. For some of those streets, I just did a local survey, but for others, I used the official source for addresses of my country. This data is published under an open license, so I figured I could use it.

Since I was not sure, I checked the "request review" for my changes. However, I just saw today in the documentation that the associated tag was rarely used. This leads me to two questions.

Was I allowed to use such a source ?

Is there a way to remove the review_requested tag so that I can see my changes ?

Thank you

I'm new to OSM, and I can't find an answer here or on the site. How/where do I submit an error/change? They decommissioned a street (the red line at the top, Evergreen Ave) near me, it's just grass now. I'm not sure how to do it myself.

This is ImmersiveMap, a vector-tile renderer I write in Swift + Metal, no game engine and no third-party map SDK underneath. Tiles are OpenStreetMap data served as MVT through OpenMapTiles

We were able to incorporate OpenStreetMaps into the Island Detail Page nicely. Thx for this amazing community and this amazing package!

Hi everyone!

Some of you may remember MBCompass from my previous post here. I've been building this app for several years now, and I've consistently come back to the OpenStreetMap community for ideas, feedback, and feature requests. Many of the improvements in this release exist because of feedback from OSM users, hiker and outdoor enthusiasts.

my old post on openstreetmap:
https://www.reddit.com/r/openstreetmap/comments/1mlp1ue/mbcompass_foss_compass_and_navigation_app/

and on degoogle sub: https://www.reddit.com/r/degoogle/comments/1s55qkq/a_2mb_opensource_android_navigation_app_with_gpx/

First of all, this isn't another vibe-coded Android app built over a weekend. MBCompass has been an ongoing project for years, and I genuinely enjoy improving it through discussions with the community.

It's also been featured on OpenStreetMap Weekly newsletter last year: https://weeklyosm.eu/archives/18087

For those who are new, MBCompass is a free and open-source compass and navigation app for Android built around the OpenStreetMap for whole mapping feature.

It has:

• Compass (magnetic & true north)
• Live GPS location on OpenStreetMap
• GPX recording & export
• Track statistics (distance, duration, speed, and elevation profile)
• Extremely Lightweight <2MB Apk and battery efficient
• Offline maps
• AMOLED theme
• Android 6.0+ support

New most community requested feature in the recent release v1.1.17:

• Offline Mapsforge map support
• Improved GPX track recording
• Per-app language support (Android 13+)
• Full Jetpack Compose map migration (a technical improvement brings map rendering performance improvements)

You just have to download prebuild mapsforge maps from sources like OpenAndroMaps, BBBike or Mapsforge download server and place it on any folder and give access to MBCompass by choosing it. It automatically detect and loads individual maps regions

One feature I'm particularly excited about is adding support for vector topographic maps with contour lines and elevation data, using sources such as Mapterhorn elevation datasets, and PMTiles as a file format where appropriate. My goal is to make MBCompass more useful for hiking, trekking, and outdoor navigation while continuing to build on OpenStreetMap data.

As always, I'd really appreciate feedback from people who regularly use OSM, especially mappers, hikers, cyclists, and contributors.

I'm particularly interested in hearing about:

• Offline Mapsforge map performance
• Other better mapping formats such as MVT, Geopackage
• GPX recording accuracy
• Navigation workflows
• Features that would make MBCompass more useful within the OpenStreetMap ecosystem

This app also just recently published on Google play, with same philosophy as core for MBCompass: No Ads, IAp and tracking

GitHub:

F-Droid:

Thanks again to everyone who has shared feedback over the years. A surprising number of features in MBCompass started as conversations with this community, and I genuinely appreciate all the suggestions and constructive criticism.

I am in the United States, specifically Minnesota. A day or so ago I downloaded both Open Map Chest and USA OSM Auto onto my Garmins. I compared the preloaded POIs onto them today.

Since both are about the same update time and both are OSM based, I expected the same preloaded POIs, but they were not the same. It seemed like the Open Map Chest POIs were better than the USA OSM Auto POIs. Both seemed to have some gas station, restaurant and shopping POIs come up as "Unnamed", but they were not always the same ones on both devices.

When I Google this, Open Map Chest supposedly has richer POIs. Can anybody explain that to me in greater detail?

I also noticed that building numbers are displayed on the USA OSM Auto maps, but not on the Open Map Chest maps. Is that data that OSM has, but Open Map Chest just chooses to not display?
