I created a site plan of a city block with elk. But now I want to create this for a complete city.
I want to do it with Bremen in Germany. I got the osm data from here: https://download.geofabrik.de/europe/germany/bremen.html
The file was too big to open in grasshopper. It loads over an hour. A friend of mine extracted only the buildings from the file with the osmium tool. But still it is too big. (12 MB)
We also tried that with the highways. This file got 2 MB and after 10 mins it works. but the result was very inaccurate.
Is there an opportunity to create a whole city or that grasshopper can handle this big file?
Thanks for help.
