Just a bit more on this -
togeo/fromgeo require input from the user.
gdt_conv_cmd does not - all the parameters are specified at the command line
(so this is the one to use).
To convert from EN to LATLONG just specify GEODETIC as the output projection
gdt_conv_cmd -a nad27 -b nutm11 -c nad27 -d geodetic
-x 480000 -y 3620000 -z 0.0
should give output of -
-117.213418 32.719307 0.000000
Here is the usage fyi...
Usage: gdt_conv_cmd [switches]
Converts a point from input datum/projection to output
datum/projection. Transformed results are printed to stdout.
as an x y z triple. Any error messages are sent to stderr.
switches:
-u Display Usage Information.
-a <datum> Input geodetic datum
-b <projection> Input geodetic projection
-c <datum> Output geodetic datum
-d <projection> Output geodetic projection
-x <double> Input x coordinate
-y <double> Input y coordinate
-z <double> Input z coordinate
Example:
gdt_conv_cmd -a nad27 -b nutm11 -c wgs84 -d nutm11
-x 480000 -y 3620000 -z 0.0
gives output of:
479920.197 3620197.254 -21.445
Hope this helps
bye
