Actually Steve's code works beautifully and does not seem to require much modernization! I haven't tested it with a subsampled envelope yet, but it spits out 4000x2000 rasters from big shapefiles in seconds. I only commented out some (not all) debug printouts and added a function to produce a GridCoverage2D directly:
public GridCoverage2D rasterize(String name, FeatureCollection fc,
String attributeName, ReferencedEnvelope env)
you can pass null as the envelope and it will use the boundaries of the
feature collection. I also internalized the FeatureRasterizerException so
the code is now self-contained as long as geotools is in the classpath. It
does not use any deprecated API - that's the extent of my modernization
capabilities :)
If I find bugs along the way I'll try to fix them - progress can be followed
at
http://ecoinformatics.uvm.edu/crucible/browse/ThinklabGeospacePlugin/org/int
egratedmodelling/geospace/gis/FeatureRasterizer.java.
Bottom line: Thanks Steve!
Cheers,
ferdinando

Hey guys; we are setting up a "Process" module in geotools (see this
weeks IRC). After you do your "testing and modernize" do you want to
send it our way? It woudl be great to have examples of different kinds
of processes to make sure the API works out okay.
