CALL "GSGDATUM" USING GSID, GSFUNSTAT.Arguments
GSID ID returned by GSINIT for the current instance of GeoStan. Input.
GSFUNSTAT Return value for the procedure. Output.
Return Values
Returns the current datum setting. Valid settings are DATUM-NAD27 and DATUM-NAD83.
Prerequisites
GSSDATUM
Notes
This procedure returns the datum currently used by GeoStan in calculating address coordinates. This setting affects only the numeric coordinates returned by GSDATGET for the latitude and longitude of an address.
A datum is a mathematical model of the Earth used to calculate the coordinates on any map, chart, or survey system. The North American Datum (NAD) is the official reference ellipsoid used for the primary geodetic network in North America.
Although the return values are DATUM_NAD27 and DATUM_NAD83, note that GTD uses WGS84 instead of NAD83. These two coordinate systems are compatible.
