The Terrain, Geoid, and Surface are implementation dependent and not mathematically precise.
The default altitude reference system that is used to provide location data depends on the GPS/GNSS radio hardware. Hardware typically found on older desktop PCs will continue using an Ellipsoid reference system. Everything else will default to using the Geoid reference system. To find out which one is being used by a Geopoint object, see the AltitudeReferenceSystem property.
|Ellipsoid Ellipsoid Ellipsoid||
The altitude reference system is based on an ellipsoid which is a mathematical approximation of the shape of the Earth.
|Geoid Geoid Geoid||
The altitude reference system is based on the distance above sea level.
|Surface Surface Surface||
The altitude reference system is based on the distance above the tallest surface structures, such as buildings, trees, roads, etc., above terrain or ground level.
|Terrain Terrain Terrain||
The altitude reference system is based on distance above terrain or ground level.
|Unspecified Unspecified Unspecified||
The altitude reference system was not specified.
