The WKT Raster extension will become the new PostGIS RASTER type in PostGIS 2.0 planned for next april. The PostGIS and the WKT Raster team met at the FOSS4G friday's code sprint and decided that WKT Raster was mature enough to bring interesting new functionalities to PostGIS. A new MapAlgebra function should be added for this release. Congratulation to the whole team for all the work accomplished!<BR><BR>

    52 The goal of '''WKT Raster''' is to implement the RASTER type '''as much as possible like the GEOMETRY type''' is implemented in PostGIS and to offer '''a single set of overlay SQL functions''' (like ST_Intersects) operating '''seamlessly''' on vector and raster coverages.
