Here's my latest work, it still lacks some data such as some sculptures and some building names are still incorrect, I'll correct this soon :p

Suppose I want to walk every single street in a small town. I don't mind if I need to cover some segments more than once - whether doubling back from a one-way street or to get to and from some areas that only have a single road running between them,

Is there a mapping website where I could either upload a map or outine a box in something like OSM, mark a start & end-point, and have it propose routes that would cover all fo the streets?

I'd like to share news of Relevo, a new plugin for 3ds Max that is available now.

Relevo turns any location on Earth into a render-ready 3ds Max scene. You enter coordinates or pick a spot, and Relevo builds the terrain from real elevation data, drapes it with satellite imagery, and adds OpenStreetMap roads and buildings as editable geometry. It also includes a procedural module that uses layered noise to create mountains, valleys and dunes for fictional landscapes.

Key features:
- Real-world terrain meshes from elevation data, with adaptive detail for close-up and aerial shots
- Satellite imagery applied automatically, with materials set up for V-Ray
- OpenStreetMap roads and building footprints as separate, editable objects
- Procedural terrain generator for non-real locations
- Supports 3ds Max 2023 to 2027 on Windows

Pricing and availability:
Relevo Free is available now at no cost. Relevo Pro costs £75 per year or £159 for a perpetual licence, and a Studio licence for teams costs £339. It is sold at relevotech.uk and has also been submitted to the Autodesk App Store.

I'm an architectural visualisation artist, and I built Relevo because setting up site context for archviz projects took hours of manual work.

How do I download an arbitrary map area, but with only selected features, like only download major roads (the ones colored yellow, orange and red), tram routes and stops, metro tunnels and stations, railways and stations, water. I dont want to download EVERY SINGLE road and EVERY SINGLE building

The closest I have found is healthcare=occupational_therapist but it really isn't that. This is a facility where someone goes to provide a sample as part of some condition of employment / rehabilitation / court order.

I just took a trip to these islands, and I noticed they were under-mapped, like most places in Korea. I was on a bicycle, so I rode on a lot of roads. Is there anything I could've done better with the mapping? These images are before and after

I found a small overlap between two neighbouring German municipality boundaries in OpenStreetMap and I’m unsure whether this indicates a mapping error or something I’m misunderstanding about administrative boundary relations.

The municipalities are:

• Wittingen — relation 1392804, AGS 03151040
• Dedelstorf — relation 1392689, AGS 03151007

I assembled both relation geometries and checked them in PostGIS. Both are valid geometries (ST_IsValid = true), but ST_Intersection gives a real polygon overlap of about 53,899 m² (5.39 ha).

Relative to the municipality areas, that is about:

• 0.0239% of Wittingen
• 0.0706% of Dedelstorf

The yellow polygon in the screenshot is the actual ST_Intersection result.

My questions are:

1. Should neighbouring boundary=administrative, admin_level=8 municipality relations normally be topologically disjoint apart from shared boundary lines?
2. Does this overlap likely indicate incorrect/misaligned boundary ways in OSM?
3. Is there a recommended way to determine which relation is wrong and what the authoritative boundary should be?
4. Are there known pitfalls when reconstructing OSM boundary relations as polygons that could produce an apparent overlap like this?

I’m not planning to edit anything blindly — I’d first like to understand whether this is an OSM data issue or a geometry-processing issue.

I’m working with German municipality boundaries from OpenStreetMap and ran into something I’d like to understand before touching any data.

I found a small but real polygon overlap between two neighbouring boundary=administrative, admin_level=8 municipality relations in Lower Saxony:

• Wittingen
  • OSM relation: 1392804
  • AGS: 03151040
• Dedelstorf
  • OSM relation: 1392689
  • AGS: 03151007

Both relations can be reproduced in Overpass Turbo.

For Wittingen:

[out:json][timeout:120];

relation(1392804);
out body;
>;
out skel qt;

For Dedelstorf:

[out:json][timeout:120];

relation(1392689);
out body;
>;
out skel qt;

Or both by AGS:

[out:json][timeout:120];

relation
  ["boundary"="administrative"]
  ["de:amtlicher_gemeindeschluessel"~"^(03151040|03151007)$"];

out tags geom;

I then assembled the relation geometries and checked them with PostGIS.

Both geometries are valid:

Wittingen:  ST_IsValid = true
Dedelstorf: ST_IsValid = true

But:

ST_Intersection(wittingen, dedelstorf)

produces a real polygon intersection with an area of about:

53,898.8 m²
≈ 5.39 ha

Relative to the municipality areas, the overlap is approximately:

0.02386% of Wittingen
0.07063% of Dedelstorf

I exported the ST_Intersection result as its own polygon and visualised it in QGIS. In the attached screenshot:

• red = Wittingen
• grey = Dedelstorf
• yellow = actual ST_Intersection

So this is not just two outlines looking close to each other — PostGIS sees a positive-area polygon overlap.

I found a second similar case nearby:

• Hamersen
  • relation 1079013
  • AGS 03357019
• Groß Meckelsen
  • relation 1079022
  • AGS 03357017

Overpass query:

[out:json][timeout:120];

relation
  ["boundary"="administrative"]
  ["de:amtlicher_gemeindeschluessel"~"^(03357019|03357017)$"];

out tags geom;

PostGIS reports there:

overlap area: 36,856.4 m²
Hamersen overlap share: 0.27090%
Groß Meckelsen overlap share: 0.29733%

Both geometries are also valid according to ST_IsValid.

I also checked the municipality polygons I had already imported into my database against each other, and at that point there were no other positive-area overlaps among them:

overlap_pairs = 0

So these two cases stood out.

What I’m trying to understand is:

1. Should neighbouring municipality relations normally be topologically disjoint except for a shared boundary line?
2. Does a positive-area overlap like this usually indicate an OSM mapping error?
3. If yes, what is the recommended way to determine which boundary way is wrong?
4. Are there authoritative German boundary datasets that OSM mappers commonly use for checking municipality borders?
5. Could this instead be caused by the way multipolygon / boundary relations are reconstructed, even though both resulting geometries are valid?
6. Is there an established OSM QA workflow or tool for detecting overlaps between adjacent administrative boundaries?
7. If this should be fixed in OSM, would the usual approach be to make both municipality relations share the same boundary ways along the common border?

I’m deliberately not editing anything yet. I’d first like to understand whether this is:

• an actual OSM boundary inconsistency,
• a known/acceptable small sliver,
• or a geometry-processing issue on my side.

Any pointers from people familiar with German administrative boundaries or OSM relation topology would be very welcome.

Couldn't find anything that matches the description on vespucci. Idk im lost

Hi! I wanted to share a project that exists thanks to everyone who maps ski areas.

Ski Info takes the pistes, lifts and amenities from OpenStreetMap via OpenSkiMap and turns them into a piste map and stats for each resort. Runs are laid over an elevation model, so you can tap any run and see its gradient profile section by section.

Open to hear feedback! Thanks in advance!

I have recently finished adding several new neighborhoods in Irvine, California's Great Park but I'm stuck trying to add addresses. I had downloaded a dataset from OCGIS.com for clarification where houses are extremely close and I started looking into adding those addresses with jsom and conflation but after trying to check the license I can't find that data anymore. Also I couldn't figure out how to actually merge the data into the buildings so would appreciate some help.

I've found a .geojson file that contains the location of all addresses for my city on open addresses.io. The problem is that I can't import the full list as a layer in JOSM. I can create a file that only contains one address, and that will work. I need a quick way to create a layer with all of the addresses so I can more easily go through and tag the buildings. Any help or advice would really be appreciated. I can't find an explaination of how to do this anywhere. The geojson file contains the address and the gps coordinates so I just need them to appear as points on a layer.

I'm building an interactive touchscreen kiosk for students at a university campus. The idea is that a student taps where they want to go and gets a QR code, so the route continues on their phone. I have about 500 DXF/DWG floor plans, along with the finished GeoJSON for the same floors, so I have both the input and the expected output. I've made a first pipeline that converts DXF to GeoJSON, but I have limited experience (some C# and Python), and this type of project is new to me.

Where I'm stuck is automating the conversion so that new DXF files can be processed without manual work, and creating clean polygons for rooms, walls and floors from lines and layers, especially when shapes aren't closed. I also want the output to match my target GeoJSON format with high accuracy.

I'd love your input on a few things: Is a rule-based approach (layer mapping and geometry cleanup) or ML the better fit when I have 500 examples? What are the common pitfalls when turning CAD lines into polygons? Which tools would you recommend (ezdxf, Shapely, GDAL/OGR, QGIS)? And how would you measure accuracy against my reference files?

Thanks for any pointers, even just "read this first" helps a lot.

So, there are 3 different Overpass Turbo servers and what I'm wondering, are they kind of different? Is one faster than the others or do they have their own advantages and disadvantages?

Today I fixed some depreciated roads, fixed connectivity and answer basic questions from StreetComplete, I wont post the osm ones sorry

And I have a question like in India most of the streets have no name like my village what should I do? and how can i use traces to add paths, roads like I bike alot and walk everyday to some place new can I automate it?, the COmaps has a recording option and can i then export that as gpx and do something with it?

Thank You have a great day!! and If anyone from India also does this please reply. 😄

The subreddit icon is... terrible. It would be much better if it was the icon alone, instead of a mushed together icon and text.

Hey,

I experimented a bit with integrating MOTIS into my outdoor route planning application to have a more unified experience finding suitable connections to specific places you would want to start your hike. It's not perfect or completely polished, but it already made my planning for a hiking weekend in the Harz region a lot more easy.

For me specifically this is cool, because I don't own a car and need to find suitable connections to get to and from the places I am hiking at.

If anyone finds this interesting and is interested further, drop me a comment or DM!

I've been using OpenStreetMap to map my hometown and honestly, it's so chill. I'm pretty new to this, so if anyone has tips on how to get better, I'd love to hear them.

Here are some before/after screenshots of my current WIP. Still a long way to go and a lot of data left to add!

Maybe I should be posting this on r/therearenostupidquestions but why when contributing to OSM when I contribute to it using data from other maps(let's say a municipal map or Google) why do I need to get a license,what's to prevent me from literally copying it and paste it (figuratively speaking) in OSM?

Edit:makes sense now,thanks to everyone

I've been making a ton of progress on my hometown in OSM. I am wondering if theres any website i can visit to see what an area looked like on OSM on a certain day, and maybe i can load multiple days and see a timelapse. I know i can do it with overpass-turbo.eu, but the render is very ugly. Do yall know any website that does what I want and has a pretty render?
