ascii2ps - create a postscript file of the data in the 3 column
ASCII input file
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
