[OSGeo-Discuss] C++ library for "gridding"

[Paul Ramsey]

I'll admit to interest, but can't really help. I would like to  
eventually add raster analytics to PostGIS, and hopefully do so  
through library linking rather than actually implementing the  
features in the core PostGIS code.  It would be nice to have a common  
library to work on this stuff in.
