# lonlatCoh2ascii(1)

create 3 column ASCII files from the binary doris output

## NAME

lonlatCoh2ascii - create 3 column ASCII files from the binary doris output

## DESCRIPTION

lonlatCoh2ascii v1.0 Doris software, TUDelft, (c)1999-2011

-

  SYNOPSIS:

- lonlatCoh2ascii

  longitude\_file latitude\_file Coh\_file output\_Coh\_file

-

  This csh-script creates a 3 column ASCII file with "lon lat coh" from the binary doris output (matrices) after step geocode. It filters out invalid data, indicated with "-999" by Doris.

-

  The output file can be used further with GMT to create a grd file. The format of the 3 input files are matrices in real4 float format. all of the same size.  They describe the irregular geocoded position of the pixels in the interferogram, and the corresponding heights.

-

  The steps taken are within this script:

-

  1\) Create 3 temporary ASCII files with all data in a single

-

  large column using cpxfiddle program;

-

  2\) Create two 3 column ASCII file (lon lat \*\*\*)

-

  using "paste";

-

  3\) remove **-999** invalid data using "grep" 4) Tidy up, remove temp files.

- These steps may take a while.

  Obviously staying in binary format

- would be better.

  This script is intented to work on all platforms,

-

  and to be straightforward and understandable, rather than ingenious.

-

  DEPENDENCIES:

-

  cpxfiddle program, part of Doris distribution. grep utility, standard UNIX paste utility, standard UNIX Note that lambda=longitude; phi=latitude

-

  EXAMPLE:

- lonlatCoh2ascii Outdata/lambda.raw Outdata/phi.raw Outdata/Coherence.raw

  lonlatcoh.dat
