iOS
typedef NS_ENUM(NSInteger, MSMapAltitudeReferenceSystem) { MSMapAltitudeReferenceSystemUnspecified = 0, MSMapAltitudeReferenceSystemTerrain = 1, MSMapAltitudeReferenceSystemEllipsoid = 2, MSMapAltitudeReferenceSystemGeoid = 3, MSMapAltitudeReferenceSystemSurface = 4 }
Values
Unspecified
The altitude value has no meaning.
Terrain
The altitude value is relative to the terrain (not including surface objects like trees and buildings).
Ellipsoid
The altitude value is relative to the WGS84 ellipsoid.
Geoid
