NAME
ascii2ps - create a postscript file of the data in the 3 column ASCII input file
DESCRIPTION
ascii2ps v1.1 Doris software, TUDELFT, (c)1999-2009
USAGE:
ascii2ps
3col_asciifile
Create a postscript file of the data in the 3 column ASCII input file containing "lon lat hei"
triplets (output of lonlathei2ascii program). GMT is used to interpolate these irregularly
distributed data to a grid.
This script is intended to be transparent and understandable. Please adapt this script to your
own needs. (lambda=longitude). For example, here one could easily set the correct approximate
height of the terrain.
The output is a postscript file named "temp.ps".
The steps foreseen to be taken are:
[before running this, create a three column ascii file with lon lat hei
using philamh2ascii program. AND optionally convert this 3 column file to UTM coordinates using
ascii2ascii_UTM
] 2) Call GMT program xyz2grd to perform interpolation of this data.
the number of points in the output grid is 300.
3) call GMT program cpt to create a color table 4) call GMT program to create a postscript file 5)
call ghostview to view output.
This script can serve as an example.
If you want to have another resolution
output grid, for example exactly 100x100 meters, then you will have to change this script. With
the public domain software PROJ, you can easily convert the WGS coordinates (Doris output) to X,Y
values, and then use this script. See the script ascii2ascii_UTM for an example how to do this
for WGS to UTM coordinates conversion.
DEPENDENCIES:
GMT tools (gmtset, minmax, xyz2grd, grd2cpt, psbasemap
psscale, grdgradient, psmask, grdimage, pscoast)
standard UNIX (echo, csh, rm, etc.) ghostview
EXAMPLE:
ascii2ps lonlathei.dat
ascii2ps xyz_UTM.dat
