[Proj] Michigan georef projection reproject to lat-lon

[Richard Greenwood]

FWTools http://fwtools.maptools.org/ (which includes Proj.4) has a
command line program called ogr2ogr which includes coordinate system
transformation. At the command prompt, you would enter something like:
   ogr2ogr destDir srcFile.shp -s_srs EPSG:codeForMichiganDNR -t_srs
EPSG:codeForLatLong
where:
  destDir is an empty destination (output) directory
  srcFile.shp is the name of the snowmobile shapefile
  codeForMichiganDNR is the EPSG number for your source data (maybe
not required)
  codeForLatLong is the EPSG number for lat-long (probably 4326)
