arc.fromP4ToWkt: Convert PROJ.4 Coordinate Reference System string to Well-known Text.

Description

The arc.fromP4ToWkt command converts a PROJ.4 coordinate reference system (CRS) string to a well-known text (WKT) representation. Well-known text is used by ArcGIS and other applications to robustly describe a coordinate reference system. Converts PROJ.4 stings which include either the '+proj' fully specified projection parameter, or the '+init' form that takes well-known IDs (WKIDs), such as EPSG codes, as input.

Arguments

proj4

PROJ.4 projection string

Details

The produced WKT is equivalent to the ArcPy spatial reference exported string:

arcpy.Describe(layer).SpatialReference.exportToString()
