Do you have trained checkpoints? It will be very grateful if you upload it!

It is awosome and I want follow your work, how can I transfrom all block polygons to a full city map, is this repo contains related scripts to do that? Thank you for your kindness reply!

Hi, since our dataset expands a lot, and new version keeps going on, we currently have no plan to release checkpoint yet. You may process your own data by downloading from OSM dataset by using OSMNX library and using warp_bldg_axis function in this repo. Then take training from scratch. GNN won't consume too much resources and training usually converges in hours.

The full city map processed by looping simple matplotlib draw function for each building and block contours. The key point is the inverse converting from your warped coordinate to real projected coordinate system (UTM, etc.). This is mostly done by the inverse_warp function in this repo.

Hope this helps!
