The pyramids are stored in the same raster data table as the geo raster object with the same srs than the original one PostGIS WKT Raster: GDAL-provided pyramids are generated on loading time at desired levels. The pyramids are stored in different tables than the original raster FOSS4G 2010 Barcelona 8 2010VCDTI Cen ro para el Desarrollo Tecnologico industrial Espai Virtual Main characteristics: Metadata deimos Oracle GeoRaster: metadata are part of the SDO GEORASTER object, and follow a XMl schema PostGIS WKT Raster: The metadata is packed with the raster data, like the georeference information Only basic metadata is stored (upper left corner, width, height, pixel size, skew, srid and numbands) FOSS4G 2010 Barcelona 9 2010VCDTI Cen ro para el Desarrollo Tecnologico industrial tana Main characteristics: Open specs deimos Oracle GeoRaster: the specs for sdo georaster and SDo RASTER objects are open this is really important to allow third party tools to provide capabilities not implemented in the server, like spatial analysis.
