1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | >>> wkt = 'GEOGCS["WGS 84", DATUM["WGS_1984, ... AUTHORITY["EPSG","4326"]]')>>> srs = SpatialReference(wkt) # could also use 'WGS84', or 4326>>> print(srs['GEOGCS'])WGS 84>>> print(srs['DATUM'])WGS_1984>>> print(srs['AUTHORITY'])EPSG>>> print(srs['AUTHORITY', 1]) # The authority value4326>>> print(srs['TOWGS84', 4]) # the fourth value in this wkt0>>> print(srs['UNIT|AUTHORITY']) # For the units authority, have to use the pipe symbol.EPSG>>> print(srs['UNIT|AUTHORITY', 1]) # The authority value for the units9122 |
