Hi Geotools members,
I'm fairly new to this tools and just discovered them when I searched
for a raster processing library. I'm not quite sure, if Geotools are the
right choice for tasks related to surface and terrain modelling or any
kind of raster based dispersion modelling. I have seen that there are
some basic raster operations implemented as included in the OGC grid
coverage specification, like mean filter or interpolation. Now I'd like
to know if it is feasible to implement own raster algorithms (e.g
curvature or any kind of flowpath calculation) or if you would stick to
other libraries. I would need something customizeable like GeoMedia Grid
or the ArcGIS Spatial analyst, but on open source basis.
I would much appreciate any help regarding my problem.

You can plugin yours own operation. There is two approachs:
1) Write yours algorithm as a Java Advanced Imaging operator
and wrap it in a GridCoverage operation.
Pro: - Best performance
- More independance regarding Geotools (you can use yours
JAI operator with other libraries).
Con: - Complex. You need good JAI knowledge.
2) Write yours own Coverage implementation (for example on top of
