Ok, that's cool, so that's in the GDAL stuff, interesting. Learn
something everyday. Although I didn't see any reference to it anywhere
in my searching.
So I took the above and made this Map File, is the correct way to
implement (it didn't work, I get a blank page still):
MAP
NAME 'test'
SIZE 800 650
STATUS ON
EXTENT 332000 -18000 678000 328000
UNITS FEET
PROJECTION
"init=epsg:26915"
END
LAYER
NAME 'tlg01'
DATA './data/tlg01/tlg_roads_l'
STATUS DEFAULT
TYPE LINE
PROJECTION
"proj=lcc"
"lat_1=44.88333333333333"
"lat_2=45.13333333333333"
"lat_0=44.79111111111111"
"lon_0=-93.38333333333334"
"x_0=152400.3048"
"y_0=30480.06096"
"a=6378418.941"
"b=6357033.31"
"to_meter=0.3048006096012192"
"no_defs"
END
END
END ## end Map
Thanbks for the help on this
