OpenTopoMap VS Openstreetmap

Have been using https://opentopomap.org for this for a while, and depending on what you're looking for it still has some advantages: does show the numbers on all height lines (osm only does the 50m one in my area for some reason, leaving you to guess whether the next one is 40m or 60m since that is not always obvious - seems like a key thing for a topographic map), does show the house numbers.

For example OpenTopoMap looks very similar to most maps that were in my school atlas. I like the MapTiler renderings too.

https://brouter.damsy.net/ The topo map is provided by https://opentopomap.org/ Alternatively, if you have an OSM account, you can go into edit mode on OSM website and drag GPX traces into the window to display them. You can't get elevation profile this way but you can use topographic map background or a better range of satellite imagery, and you can use Bing imagery without an API key.

The chances of the problem not having being already tackled with deterministic algorithms is the thinnest - and in fact, yes, there do exist tools, as expected.

See the sections about 'hillshade' at the OpenTopoMap "from scratch" instructions, at https://github.com/der-stefan/OpenTopoMap/blob/master/mapnik...

I have generated and hosted locally an instance of OpenTopoMap covering South America. Now I want to create a set of MBTiles for each individual country. Using the Raster tools -> Generate XYZ tiles (MBTiles) I can do that for a rectangular extent (drawn on map or calculated from layer). Can I do it for an irregular shape? I downloaded a .shp file for Argentina, for example - https://i.imgur.com/3IGJ88A.png

Plenty of those around here (not all 5 way but you get the jist):

My my local pet peeve of horrible roundabouts, you got cycling paths, a tram line, a bus line with different exit and cars. (the hexagonal cycling path with internal car circle causes the cars to not see a lot of the cycling paths making accidents frequent): https://www.openstreetmap.org/#map=19/51.996997/4.354979

Plus the countless documentation websites that we technical writers lovingly toil away at day-in and day-out.

With the core goal to build a free, editable map of the world, OpenStreetMap's website repo is where all the magic happens.

I've outlined the server capabilities. If I had more time, I'd play around building an interesting local map using open data (like OpenStreetMap), but I'll leave it as it is for now.

We use OpenAI's CLIP model (https://openai.com/index/clip/) to put texts and images into the same embedding space. We do a similarity search within this space using text query or source image. We are using CLIP finetuned on pairs of satellite images and OpenStreetMap (https://www.openstreetmap.org/) tags (https://github.com/wangzhecheng/SkyScript) because vanilla clip performs poorly on satellite data. We pre-segment objects using Meta's Segment Anything Model (https://segment-anything.com/) and pre-compute CLIP embeddings for each object.

We'd love to hear your thoughts! What worked well for you? Where did it fail? What features do you wish it had? Any real-world problems you think this could help with?

This seems to be a constant around the world. Just look at how many towns have been built closer to Vesuvius than Pompeii: https://www.openstreetmap.org/?mlat=40.75&mlon=14.49

The Android app StreetComplete is an excellent start for updating OSM I found. There soon become occasions when you have to bring out the big guns and edit it using the web editor at https://www.openstreetmap.org/ , which is possible to do on a mobile phone if it has a big enough screen, but much easier on a laptop.

Best (simplest) options for contribution are:

- StreetComplete - gamification of adding missing properties for existing objects. Consider it as most basic and limited

- https://every-door.app/ - the best option to update and add amenities (shops, restaurants, etc) on the go.

- iD browser editor available at https://www.openstreetmap.org/ - you will need at least this complexity to add objects with geometry (linear or area)
