phase2topo

## NAME

phase2topo - phase2topo

## SYNOPSIS

**phase2topo** *master.PRM topo\_in.grd res\_phase.grd topo\_out.grd*

## DESCRIPTION

This program is part of GMTSAR.

-

  phase2topo \[GMTSAR\] - Compute residual topography

- master.PRM

  \- master PRM files used for mapping

- topo\_in.grd

  \- name of input topography in the radar co-ordinates of the master.

-

  res\_phase.grd - name of input phase per unit baseline topo\_out.grd  - name of output corrected topography in the radar co-ordinates of the master.

-

  Note the residual phase should be scaled by the perpendicular baseline (see bperp).

-

  phase2topo \[GMTSAR\] - Compute residual topography
