Lat Lon Quad
Allows nonrectangular quadrilateral ground overlays.
Specifies the coordinates of the four corner points of a quadrilateral defining the overlay area. Exactly four coordinate tuples have to be provided, each consisting of floating point values for longitude and latitude. Insert a space between tuples. Do not include spaces within a tuple. The coordinates must be specified in counter-clockwise order with the first coordinate corresponding to the lower-left corner of the overlayed image. The shape described by these corners must be convex.
If a third value is inserted into any tuple (representing altitude) it will be ignored. Altitude is set using GroundOverlay.altitude and GroundOverlay.altitudeMode extending GroundOverlay. Allowed altitude modes are AltitudeMode.absolute, AltitudeMode.clampToGround, and AltitudeMode.clampToSeaFloor.
Properties
Four or more tuples, each consisting of floating point values for longitude, latitude, and altitude. The altitude component is optional. Do not include spaces within a tuple. The last coordinate must be the same as the first coordinate. Coordinates are expressed in decimal degrees only.
