Hey ArcGIS API for Python staff on GeoNet, I found a bug for you. It turns out the __geo_interface__ methods generate different, and incorrect, output when ArcPy is not installed along with ArcGIS API for Python. >> > from arcgis . geometry import Geometry >> > from pprint import pprint >> > >> > # simple square with a hole in the middle . . . json = { . . .
