# offset\_topo(1)

offset\_topo

## 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

offset\_topo \[GMTSAR\] - Determine topography offset
