Mississippi Transverse Mercator (MSTM)

The MARIS Technical Center (MTC) and the Mississippi Department of  Transportation (MDOT) jointly developed a map projection for Mississippi called; the Mississippi Transverse Mercator (MSTM) Projection. When viewing geographic  data on a statewide level, the MSTM projection alleviates the multiple-zone conflict inherent in UTM and State Plane systems.The problem with both of these; systems is that each divides the state into an east and west zone that cannot be  digitally displayed together.

The MSTM projection is a customized Transverse Mercator projection designed; to more evenly distribute convergence and scale-factor, and is based on the; North American Datum of 1983 (NAD83). The projection parameters of the MSTM  projection are as follows:
