Sorry, no OGR does not support MGRS.   It has been several months
since I did something with MGRS so my memory is a bit foggy on the
details, but I believe that MGRS coordinates interleave the X and Y
digits including some non-numeric prefixes to identify a grid square.
So it is hard to represent MGRS as a "coordinate system definition"
and a set of x/y points.   For that reason, I don't think it is really practical
to talk about having OGR support MGRS as a coordinate system. 

However, if you need to convert values to/from MGRS there is some
code for it buried in the NITF driver.  Try reviewing:


The MGRS code is derived from Geotrans.
