coreLabelTools.py function createRasterFromGDF: make np.zeroes instead of np.empty #92

Open asaic opened 5 years ago

asaic commented 5 years ago

coreLabelTools.py function createRasterFromGDF currently does this for an empty geojson (=no buildings):

burned = np.empty(rst.shape, dtype='uint8')

This gives a somewhat random array depending on what was in memory. But if I understand correctly, what we want is an array with all zeroes:

burned = np.zeros(rst.shape, dtype='uint8')
