Dear all I would like to take a broader view of the issue of raster data in a DBMS. Issues of performance are relevant, but the benefits of having raster data on a DBMS are much more important.
Consider that raster sensors and grid models are by far the dominant source of new geospatial data. If FOOS4G solutions do not include the capability of handling raster data in a DBMS, they would be lacking in functionality compared to commercial solutions from Oracle and ESRI. INPE´s FOSS4G developement of raster data on RDBMS using the TerraLib library is a tangible proof of concept. TerraAmazon (built using TerraLib) is INPE's OS solution for monitoring tropical forests operationally. The application was described in a recent article on the OSGEO journal, and it is arguably one of the biggest geospatial databases built using FOSS4G. Hundreds of images and hundreds of thousands of polygons are used operationally in Brazil´s real-time monitoring of deforestation. We hope our example helps to convince the community that we should not waste time arguing that we shouldn't store raster data in DBMS. FOOS4G needs this capability. Better yet, we already HAVE this capability on a production level.
