AltitudeReferenceSystem AltitudeReferenceSystem AltitudeReferenceSystem AltitudeReferenceSystem Enum

Indicates the altitude reference system to be used in defining a geographic shape.

Syntax

Declaration

public enum AltitudeReferenceSystempublic enum AltitudeReferenceSystemPublic Enum AltitudeReferenceSystempublic enum AltitudeReferenceSystem

Remarks

The Terrain, Geoid, and Surface are implementation dependent and not mathematically precise.

Note

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.

Fields

Ellipsoid
Ellipsoid

The altitude reference system is based on an ellipsoid which is a mathematical approximation of the shape of the Earth.

Geoid

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
