Option Name Description
Coordinate system

This field specifies the coordinate system to use for the geometry.

To change the default coordinate system, clear the default value then start typing the name of a coordinate system or an EPSG code to see a drop-down list of systems that begin with or contain those characters (the list appears after you have entered three alphanumeric characters). You can also click the browse button to open the Select Coordinate System dialog and select one from the list. Regardless of which coordinate system you select, the descriptive name will appear in the field and the respective EPSG code is saved for the stage.

For more information on EPSG codes, see To retrieve a list of supported codespaces for EPSG, you can submit the SOAP request List Supported CoordSys by Code Space from the Geometry Service Demo page at http://<server>:<port>/Spatial/GeometryService/DemoPage.html.

WKT string The field containing the WKT string to convert to a Spectrum Spatial geometry; for example, POINT (30 10) or MULTIPOLYGON (((30 20, 45 40, 10 40, 30 20)), ((15 5, 40 10, 10 20, 5 10, 15 5))).
Geometry field The name of the field that you want to contain the geometry returned by Spatial Calculator; the default is Geometry.
