I want to create my own projected coordinate system based on one of geographical coordinate systems and set custom values to properties as
I found SpatialReference class.
But can't understand how set geographical coordinate system that will be base for my coordinate system -
GCS property is read only, and no methods for set its value.
And also, when I calls
create method, result is
RuntimeError: ERROR 999999: Error executing function.
Article has example with only reading existing property, but hasn't examples with creating CS.
What am I doing wrong, and where can I find examples for CS creating?
new_sr = arcpy.SpatialReference() new_sr.linearUnitName = u'meters' new_sr.longitude = 30 new_sr.longitudeOf1st = 10 new_sr.longitudeOf2nd = 50 new_sr.longitudeOfOrigin = 30 new_sr.projectionCode = 100500 new_sr.projectionName = u'my_projection' new_sr.scaleFactor = 2 new_sr.standardParallel1 = 50 new_sr.standardParallel2 = 60 new_sr.create() # RuntimeError: ERROR 999999: Error executing function
May be I must set some other properties, or vice versa remove unnessecary?
