Detailed Description

This object carries most, if not all, intelligence specific to the MGRS (Military Grid Reference System) grid standard. It can be used at two distinct levels, depending upon how it is manufactured.

When manufactured with an ellipsoid/datum specification, this object is suitable only for conversion of geographic coordinates to MGRS strings and vice-versa.

WHen manufactured with a frame coordinate system with a grid boundary subsequently supplied, the resulting object is capable of NGRS string conversions AND the generation of MGRS grids.

When manufactured using a frame coordinate system and subsequent provision of a frame boundary (see base class MgCoordinateSystemGridBase) the members derived from the MgCoordinateSystemGridBase base class can be used for MGRS grid drawing purposes.
