I created a "custom" CRS with specifications I got from someone who needs the data in that specific system. It worked well and I now have a *.prj file, so basically a WKT-representation of that CRS. How can I find out if it already exists as some "official" CRS which might even have an EPSG code?
I tried this with Python / OSR:
from osgeo import osr sr = osr.SpatialReference() wkt = '''MY_WKT''' sr.ImportFromWkt(wkt) # returns 0, so that worked sr.AutoIdentifyEPSG() # returns 7, of which I don't know the meaning, but it does not seem to work sr.GetAttrValue('AUTHORITY', 1) # returns '4326', but MY_CRS is not the standard WGS84, so that's definitely wrong
Does that mean that my CRS is "truly custom" since there is no EPSG for that? Is there another way of finding out whether it already exists or not?
