Output Spatial Reference

Raster Analysis tasks that have the outSR property in their Context parameter will save results in the specified spatial reference.

Spatial Reference syntax:

"outSR": {"wkid" : <wkid>}

The spatial reference is specified with a WKID (well-known ID). Each WKID number is unique to a specific spatial reference. For a list of all the WKID numbers and their corresponding spatial references, see Projected Coordinate Systems and Geographic Coordinate Systems.

Spatial Reference example (GCS_WGS_1984)

"outSR": {"wkid": 4326}
