[ gpsdrive ] WMS fetching script for gpsdrive

[Hamish <hamish_nospam@yahoo.com>]

Hi,

I have modified the r.in.onearth script for GRASS GIS by Soeren Gebbert*
to download and register maps for GpsDrive (tested with 2.09).

The script:
  http://bambi.otago.ac.nz/hamish/gpsdrive/fetch_onearth.sh

[*] Soeren's site:
  http://www-pool.math.tu-berlin.de/~soeren/


USAGE: fetch_onearth.sh center_longitude  center_latitude  scale
 e.g.  fetch_onearth.sh 170.5 -45.0 150000

It is currently set up to download LANDSAT-7 visual composite images
  (30 meter/pixel minimum resolution [1:85000]  [maybe 15m??])

by uncommenting some statements at the start of the script you can
have it download other satellite data:

* WMS Global Mosaic, a High Resolution, Global Coverage, Landsat TM 7
  mosaic (all spectral bands)
* Radar reflectance images produced by the SRTM mission
* Blue Marble Next Generation, one for each month of the year
* Composite of data produced by the MODIS Rapid Response System, from
  data collected yesterday by the MODIS/Terra
* Composite of data produced by the MODIS Rapid Response System, from
  data collected yesterday by the MODIS/Aqua


It could be generalized even further to use any WMS server: see the
r.in.wms shell script that comes with GRASS 6.2.0.

This script is hardcoded to talk to NASA's Onearth WMS server: 
  http://onearth.jpl.nasa.gov


It is a bit of a hack (my fault, not Soeren's), but all seems to work
ok. it could use some checking of input params, etc.

it needs "bc" & it could be rewritten without GDAL tools, but you
should really have those installed already.

My hope is that someone (else) will merge the functionalily into
gpsfetchmap.pl. It's pretty simple, the whole thing is really just a
wrapper for composing the wget --post-data string.


enjoy,
Hamish
