API Reference › core-frontend › Tiles › MapCartoRectangle

MapCartoRectangle Class

A specialization of Range2d representing a Cartographic region on the surface of the Earth, used by MapTiles. The x components of the low and high points refer to the western and eastern longitudes, respectively. The y components of the low and high points refer to the southern and northern latitudes, respectively. Longitudes are stored in radians in the range [-pi, pi]. Latitudes are stored in radians in the range [-pi/2, pi/2].
