For best performance, when a geospatial system function exists that performs the same functionality as a geospatial UDF, use the system function.

If your SQL statement specifies the name of a geospatial system function that is also the name of a geospatial UDF, Teradata Database calls the system function. To call the UDF, qualify the name of the UDF with the SYSSPATIAL database name.
