Be aware of CRS

[eliasm56]

Thank you for the wonderful code. I have a deep learning model trained for building detection and this repo had exactly what I needed to create presentable polygons. The only thing I will say is that you need to be careful with CRS. If you are working with polygons in a specific CRS that is not WGS84, you will receive an error. As referenced below, WGS84 is hard-coded into the algorithm, so please be aware that you will need to change these hard-coded CRS values or reproject your original data for the operation to work.

	# Create WGS84 referenced GeoSeries
	bS = gpd.GeoDataFrame({'geometry':[polySimple]})
	bS.crs = "EPSG:4326"
	# Temporary reproject to Merkator and rotate by median angle
	bSR = bS.to_crs('epsg:3857')
	bSR = bSR.rotate(angle, origin='centroid', use_radians=False)
	bSR = bSR.to_crs('epsg:4326')
