Hi devs,
The raster terrain plugin is in trunk now (at the moment without analysis lib,
but I plan to do that soon).
Regards,
Marco

Hi QGIS devs
I'd like to announce the QGIS raster terrain plugin. It calculates slope,
exposition, ruggedness and total curvature based on a 3*3 window for each cell
of a raster. The plugin keeps attention that only three raster rows are in
virtual memory at a time, so it is also possible to process large rasters.
If you like to test the plugin, you find the source on:
http://karlinapp.ethz.ch/raster_terrain_analysis.tgz
Just unzip it in the src/plugins directory and add 'raster_terrain_analysis'
as a new subdirectory in src/plugins/CMakeList:
SUBDIRS (copyright_label
delimited_text
interpolation
north_arrow
scale_bar
oracle_raster
raster_terrain_analysis
)
Note that the code is not well tested yet, so drop me a mail if a result seems
strange or you have other comments / suggestions / code improvements.
I thought that this plugin could ev. go into the upcoming analysis library of
QGIS. Btw. are there any objections on merging the branch with the analysis
library after the release of 1.2 and using the library for the interpolation
and raster terrain plugin? fTools will come later I think as it probably is a
lot of work to port the python code to C++...
Regards,
Marco
