Summary
Returns a list of available spatial reference names for use as an argument to the SpatialReference class.
Syntax
ListSpatialReferences ({wild_card}, {spatial_reference_type})| Parameter | Explanation | Data Type |
wild_card | Limits 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. | String |
spatial_reference_type | Limits the spatial references listed by type.
(The default value is All) | String |
| Data Type | Explanation |
| String | A 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 you limit your search or better understand the purpose of the spatial reference. For example, '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: '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
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_namePrint 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} {0.name}".format(sr_object)
