I realize that it would only be a drop in the bucket, but would seeking Google Summer of Code funds be a helpful avenue?

Hi all,

For myself, I will start to work on the project about 15 hours per week in march 2009. At this rhythm, we won't have a beta before winter 2010. This is why help would be welcome.

So two programmers would be working on the project if someone can fund Sandro. One full time (Sandro), one half time (me). For now Sandro has very few money and I'll have few time.

The main idea of WKT Raster is to treat raster tiles as much as possible like PostGIS geometries so we could query and analyse (intersection, overlay, interpolation, conversion, etc...) vectors and rasters seamlessly. WKT Raster is much simpler than Oracle Georaster and much more GIS oriented (like PostGIS is).

A PowerPoint of the design is available at http://www.cef-cfr.ca/uploads/Membres/WKTRasterPostGIS.ppt
