Import Esri PRJ file as GCS

WKT (Well-known Text) is a standard way of defining geographic coordinate systems in addition to other geographical objects. OpenCities Map provides a key-in to import a text file with WKT, create and assign a geographic coordinate system (GCS). This text file is typically an Esri PRJ file associated with a SHP file.

Key-in: MapCSUtilities ReadWKT <filespec>

The file specified by filespec will be read and assigned as a GCS in the active file. The filespec should be a fully qualified file specification.

Note: The key-in does not accept spaces and special characters in the file or folder name.

If the file is read and assigned correctly, a message will be displayed saying that the command succeeded.

If the command fails then a message will indicate that it failed and there may also be further details.

Possible causes of failure:

  • File not found
  • Datum not interpreted correctly
Note: This tool creates a GCS from WKT and assigns it to the active file. It will replace an existing GCS without prompting you to reproject or to change the storage units. Be sure to run this command on a copy of your data.
