Grass rasters

The module supplies support for reading and writing GRASS rasters. The metadata contain both the colortable and the categories (if available) of the raster map. The original colortable of the GRASS raster is read into the geotools coverage Categories and can as such be visualized if using a default styler.

Data structure of a rastermap

Raster data in GRASS are stricktly bound to their workspace. Since a workspace is something more on userlevel, I will from now on use grass database for the folder structure and workspce for what the user will interact with at application level.

A GRASS raster map consists of several files in several subdirectories in a mapset, organized as follows:

Module Status

The module derives from code that has been used and tested for years in the JGrass community and shall be defined as tested as such.
In fact the creation of the module forced me to introduce a couple of geotools interfaces that were not in the library before.
That said, a complete set of tests are available that check the reding at different resolutions and regions.
