This class represents a coordinate reference system (CRS).
Contains information about the context in which a coordinate transform is executed.
A structured metadata store for a map layer.
A rectangle specified with double values.
Encapsulates properties of a vector tile matrix set, including tile origins and scaling information.
Utility class for reading and writing ESRI VTPK files.
