Our PostGIS development team has gotten a new addition as well. We have Bborie Park hailing from UC Davis Center for Vectorborne Diseases helping out on the raster front.
You might have seen him on the PostgreSQL news groups asking questions.
He is currently working on raster image export functions, so that you can do things like ST_AsPNG(rast,...) right from
the database. In addition he is also working on raster statistics functions like histograms, mean, minmax, stddev, reclass functions.
Bborie, if you get some of this in for 2.0, I promise to help document these new functions and to write an ASP.NET and PHP application/tutorial that flaunts some of them.
Bborie just committed all these functions to PostGIS code base. I'm starting to add them to the documentation and start testing them now. We'll release a windows experimental build with these in them in the next couple of days. Yee Pee!
