xm_xsec


NAME
     xm_xsec - cross section format for the xmap8 program

SYNOPSIS
     xm_xsec - Input File Format

DESCRIPTION
     For providing XMap8 with a description of  a  set  of  cross
     sections.

     You can get xsec files loaded  by  using  the  -X  xsec_file
     option


FORMAT
     Files are free format with this input:
     lat1 lon1 lat2 lon2 dip min_depth max_depth front back

     where,
     lat1,lat2  = latitude, positive north
     lon1, lon2 = longitude, positive east

     point 1 (lat1,lon1) is the start of the cross section.
     dip is measured in degrees from vertical
     min_depth = starting depth of cross section
     max_depth = bottom depth of cross section

     front = width of swath (km) to the right of cross section if you are
             located at point 1 facing point 2.
     back  = width of swath (km) to the left of cross section if you are
             located at point 1 facing point 2.

     (the swaths can have different front and back.  This is mainly useful
     for dipping cross sections)
