gpx2gml.py GPX format to GML coverter. This little python script converts your GPX files to GML, and maybe more in the future. You can specify, which tracks you want to convert, so you do not have to do this manually later in your GIS. Resulting GML file is 3D and can be converted e.g. to ESRI Shapefile using ogr2ogr utility.

For scripts, you can either
- set your GRASS_ADDON_PATH and copy the file in there:

r.gauss — Gaussian filter. The module
is controlled by size of the matrix and sigma. This module provides also
the Laplacian of Gaussian filter, which can be used for edge detection.

r.mlv — Mean of least variance. The Mean
of Least Variance (MLV) filter is an edge-preserving (actually
edge-enhancing) noise smoothing filter based on the concepts of mathematical

r.bilateral — Bilateral filter.
It is an edge-preserving filter, which takes both — spatial and color part
of the map into count.

Fragstats is a computer software program designed to compute a wide variety
of landscape metrics for categorical map patterns.
NOTE: This Fragstats version — 2.0 — is buggy: it can not handel rasters with NULL
values. New version of Fragstats — 3.0 — can be used with MS Windows only.

raster files boundaries. The best version of GRASS is 6.1+. If you are using
GRASS < 6.1, you have to be in the same mapset as your raster maps are from.
