Class LatLng

java.lang.Object

com.dingi.dingisdk.geometry.LatLng

All Implemented Interfaces:

android.os.Parcelable

public class LatLng
extends java.lang.Object
implements android.os.Parcelable

A geographical location which contains a single latitude, longitude pair, with optional altitude.

Latitude and longitude are expressed as decimal degrees in the WGS84 datum. By default, altitude is 0.0, or sea level.

Dingi GL displays maps in the Mercator Projection and projects geographical data automatically, so all data enters in the WGS84 datum.
