[GRASS-dev] gpde lib movie

GRASS GIS GRASS GIS developer

Hi folks,
i have implemented a new groundwater solute transport module based on the new
grass gpde library. The module is just a frontend to the gpde library to feed
it with data. :wink:

I have created a small video based on the groundwater flow module r.gwflow and
the new not for the public yet available r.solute.transport module.

The movie shows solute transport in a steady state groundwater stream.

http://www-pool.math.tu-berlin.de/~soeren/grass/modules/screenshots/r.solute.transport_animation.avi

The solute transport module will be available for public if i can assure
physically correct solute transport calculation.

The movie is based on this script:
http://www-pool.math.tu-berlin.de/~soeren/grass/files/gwflow_transport_script.sh

and mencoder.

Best regards
Soeren

Hi Soeren.

Nice movie. One suggestion: use r.colors to set common color rules for
all interations based on max range (log scale?), then use d.legend range=
option to keep the legend stable between frames, even when the raster in
that frame only covers a part of the overall range.
