Check multiple feature classes have same spatial reference

Question

As the title says I've several feature classes. I want to check whether they have same spatial reference using arcpy

Answer 1

you can do it with this way:

import arcpy
env.workspace = "D:/test/data.gdb"
fcs = arcpy.ListFeatureClasses()
ary = []
for ft in fcs: 
 desc = arcpy.Describe(ft)
 spatialRef = desc.SpatialReference
 ary.append([spatialRef.Name, ft])
 print spatialRef.Name
# Finding the same Spatial Reference Object
for a in range(len(ary)):
 if ary[a][0] == 1:
 print ary[a]
# Finding different form other Spatial Reference Object
for a in range(len(ary)):
 if ary[a][0] > 1:
 print ary[a]

i hope it helps you...

• user: I'm just a programmer working on a GIS software. Do spatialRef.Name always identifies the projection? Is checking spatialRef.Name equals is enoguh?
• urcm: spatialRef.Name will give you Map Projections as Mercator, Gauss-Kruger or Lambert Conformal Conic. if you want to learn spatial reference code you can use desc.SpatialReference.factoryCode
