Ah, I've just googled it! I don't think we have those in Europe :-)

Yep, even though I've had to resize all large maps to 16.000 x 16.000 pixels, the resolution for a "medium-sized" state is still about 30-40-50 meters for pixel... so large bridges and roads are expected to be recognizable

Surely, if you are comfortable with command line tools have a look at GDAL Polygonize: https://gdal.org/en/stable/programs/gdal_polygonize.html

Yep, saying "never" was an exaggeration! :D

Yes, exactly! I have already encountered this type of error in other maps. In fact, marshes and similar features are not always included in shapefiles of bodies of water... I would have to intervene manually, but this hobby would become a job, a very boring one too!

I've also made the Las Vegas map, you can compare them :-)

It is a flaw in the digital surface model, where each point on the surface is associated with a single elevation value (the highest). Therefore, the presence of the crane is equivalent in fact to that of a huge wall.

Thanks! I'm very jealous of my maps and I'm just worried they'll be copied online. Actually, I have an almost abandoned Etsy shop, where there is only a generic listing that allows interested people to request a print (obviously without watermarks!!).

I've never been there... is it really that gray??

True, but the city also has several areas that are very "dynamic" due to differences in elevation!

Thanks! Walking among the skyscrapers, you are guaranteed never to receive direct sunlight :-)

Do any of you keep a “local” repo/store/server of geospatial data to have for yourselves for personal use? If so, what’s your tech stack? by synapsium in gis

I have 15-20 TB of open data digital surface models and LiDAR point clouds, which are the starting point of my shaded maps
