GeoCoordinate

Coordinate in Mercator.

This coordinate system is used to locate an object’s geographic location as it would appear on a map. Examples include the GPS position of the ego-vehicle or the position of landmarks, which can be used for localization or position of the detected objects.

Currently we use Spherical Earth Model for geodesic calculations. Each point is specified using longitude, latitude.

Longitude ranges from -180 to 180 degrees, where 0 is Greenwich meridian, the positive direction (+) is to the East, and the negative direction (-) is to the West.

Latitude ranges from -90 to +90 degrees, where 0 is Equator, the positive direction (+) is to the North, and the negative direction (-) is to the South.
