NAME

       offset_topo - offset_topo

SYNOPSIS

       offset_topo amp_master.grd topo_ra.grd rshift ashift ns [topo_shift.grd]

DESCRIPTION

       This program is part of GMTSAR.

       offset_topo [GMTSAR] - Determine topography offset

              amp_master.grd  -  amplitude image of master topo_ra.grd    - topo in range/azimuth
              coordinates of  master  rshift          -  guess  at  integer  range  shift  ashift
              -   guess   at  integer  azimuth  shift  ns              -  integer  search  radius
              topo_shift.grd - shifted topo_ra - optional, will be shifted by rshift, ashift
