pls suggest me a good building.geoson and corresponding image tiles to perform the experiment.

It will be great if you can share image tile and building tiles for experiment .
data can be used and proved that it is working well. then I can use your code with my data sets.

download the GeoTIFFs and cut out the tiles where there are buildings
