Coordinate system specification causing empty poly_stream.element drawing #94

Closed kcpevey closed 6 years ago

kcpevey commented 6 years ago

coord_sys = ccrs.UTM(15)
ann = PolyAndPointAnnotator(tile_url='https://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer/tile/{Z}/{Y}/{X}', crs=coord_sys)  
ann.tiles * ann.polys * ann.poly_view * ann.points  

ann.poly_stream.element

Specifying coord_sys = ccrs.GOOGLE_MERCATOR allows for the polygons to be redrawn with ann.poly_stream.element. However, coord_sys = ccrs.UTM(15) causes ann.poly_stream.element to draw no polygons.
