lonlatCoh2ascii - create 3 column ASCII files from the binary
doris output
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
- SEE ALSO:
- cpxfiddle, paste, grep, http://gmt.soest.hawaii.edu/
