%%%Is there any program similar to m.ll2u for converting ll to state plane
%%%coords?  I see the setup file with ll and state plane data (state27) in
%%%the etc directory, leading me to believe that there something should be
%%%around for the conversion.  I'm working in the florida east zone, 1927
%%%datum. 
%%%
%%%Thanks very much,
%%%

Carl,

In 4.0 GRASS command m.geo.
In 4.1 GRASS command m.proj.
Or, use the MAPGEN proj command directly:

# 901:florida east datum:NAD27
901: +proj=tmerc +a=0.63782064e+07 +es=0.6768657997291094e-02 
+x_0=0.1524003048006096e+06 +y_0=0 +k=0.9999411764705882e+00 
+lon_0=81dw +lat_0=24d20'n

*proj* from PROJ.4 executed with the following script

proj +proj=tmerc +a=0.63782064e+07 +es=0.6768657997291094e-02 
+x_0=0.1524003048006096e+06 +y_0=0 +k=0.9999411764705882e+00 
+lon_0=81dw +lat_0=24d20'n <<EOF
LONG LAT
LONG LAT
EOF

For the specifics on using the MAPGEN proj command for STATE Plane
request help from Jerry Evenden at gie at charon.er.usgs.gov.  He will be
able to tell you exactly what to enter, I'm giving you my best guess.

Jill
