ListSpatialReferences (arcpy)


Returns a Python list of available spatial reference names for use as an argument to arcpy.SpatialReference.


ListSpatialReferences ({wild_card}, {spatial_reference_type})
ParameterExplanationData Type

Limit the spatial references listed by a simple wildcard check. The check is not case sensitive.

For example, arcpy.ListSpatialReferences("*Eckert*") would list Eckert I, Eckert II, and so forth.


Limit the spatial references listed by type.

  • GCSList only Geographic Coordinate Systems.
  • PCSList only Projected Coordinate Systems.
  • ALLList both Projected and Geographic Coordinate Systems. This is the default.

(The default value is All)

Return Value
Data TypeExplanation

A Python list of spatial references that match the wildcard and spatial reference type. Each item in the list includes qualifying information, separated with forward slashes, to help limit your search or better understand the purpose of the spatial reference.

For example, u'Projected Coordinate Systems/World/Sinusoidal (world)' might be in the list. You can see from the path that this spatial reference is Sinusoidal, is a projected coordinate system, and is intended to be used at a global extent.

Here is another example: u'Projected Coordinate Systems/UTM/South America/Corrego Alegre UTM Zone 25S'. This is a UTM spatial reference for a UTM zone in South America.

Code Sample

ListSpatialReferences example 1

List all geographic spatial references.

import arcpy

# Get the list of spatial references and print it.
srs = arcpy.ListSpatialReferences(spatial_reference_type="GCS")
for sr_name in srs:
    print sr_name
ListSpatialReferences example 2

Print the central meridians and names of UTM zones in New Zealand.

import arcpy

# Get the list of spatial references
srs = arcpy.ListSpatialReferences("*utm/new zealand*")

# Create a SpatialReference object for each one and print the
# central meridian
for sr_string in srs:
    sr_object = arcpy.SpatialReference(sr_string)
    print "{0.centralMeridian}   {}".format(sr_object)
