PROGRAM
     vll2utm - Convert explicit location data from geographical
     coordinates to utm.

SYNTAX
     vll2utm

     -i             input file

     -o             output file

     [-s]           Locations in seconds or degrees (1=seconds)

     [-V]           Gives the version for vll2utm

     [-U]           Gives the usage for vll2utm

     [-P]           Prompts for command line options

     [-A [file1]]   Creates the answer file called vll2utm.ans or
                    file1

     [-a [file1]]   Uses vll2utm.ans or file1 as the answer file

DESCRIPTION
     vll2utm converts explicit location data from geographical to
     universal transverse mercator coordinates.

             When digital elevation model data is imported using
     dem2viff, it is optional to write explicit location data
     along with the elevations.  If the file input to dem2viff is
     a 1-degree DEM file, the explicit locations will be given in
     arc seconds of latitude and longitude.  This program may be
     used to convert the coordinates in arc seconds to their
     equivalents in utm.  This is desirable because the other
     geographical information programs in Khoros use locations in
     utm.

             The -s flag specifies whether the geographical coor-
     dinates are given in degrees or arc seconds.  Dem2viff will
     always write geographical coordinates in arc seconds, but
     the degrees option has been included for possible future
     use.

REQUIRED ARGUMENTS
     -i     type: infile
            desc: input file

     -o     type: outfile
            desc: output file

OPTIONAL ARGUMENTS
     -s     type: boolean
            desc: Locations in seconds or degrees (1=seconds)
            default: true

EXAMPLES
     dem2viff -i dem.file -o elevation.img -l 1

     vll2utm -i elevation.img -o elevation.img.utm

     This sequence of commands first uses dem2viff to import a
     DEM data file.  The -l 1 file specifies that explicit loca-
     tions will be written with the elevation data.  If the DEM
     file input to dem2viff is a 1-degree DEM, the explicit loca-
     tions will be given in arc seconds of latitude and longi-
     tude.  Finally, the explicit locations are converted to utm
     coordinates using vll2utm.

RESTRICTIONS
     vll2utm requires that the input file contains only one image
     and that the image must contain explicit location data.
