UTM: Universal Transverse Mercator System
This variation implements the same algorithms as the standard Transverse Mercator projection. However, the definition parameters are specifically tailored for the definition of zones of the Universal Transverse Mercator (UTM) system of coordinate systems.
Parameter Name |
Description |
PARM1 |
UTM zone number. Note that this must be an integer value between 1 and 60, even though it is carried in a variable of the double type. |
PARM2 |
The hemisphere of the zone. Use a positive one for northern hemisphere and a negative one for the southern hemisphere. |
MAP_SCL |
Used only when defining a coordinate system that is to produce measurements on a scaled paper map. This value is the scale of the map, e.g., 100,000. Normally, this value is set to 1.0. |
