Class Method Details

.create(name_, geographic_coordinate_system_, projection_, linear_unit_, axis0_, axis1_, *optional_) ⇒ Object

Create a ProjectedCoordinateSystem given a name, a GeographicCoordinateSystem, and Projection, a LinearUnit, and two AxisInfo objects. The AxisInfo objects are optional and may be set to nil. You may also provide the optional parameters specified by the Info interface.
