Hi Mike,
A product for managing (muti-dimensional) raster data within a database that I've been monitoring since around 2002 has just been released under GPL. They have also applied for OSGeo Incubation. This product, Rasdaman, can be used with Postgres as its data store. Rasdaman has its lineage going back to around 1995 (I think). They are claiming the French government as a client using the product to manage TB image mosaics. I understand that there is a sister product that will soon be merged in with Rasdaman that offers good OGC support (WCS 1.1 and 2.0, WMS and WCPS). We intend investigating this product as a potential tool for managing grid, model and multi/hyperspectral remotely sensed data relating to the Climate domain. If you look at the product, let me know. I'll be happy to share experiences. See [1] for Rasdaman product information and [2] for example implementations. ====== Another option is the Brazillian Terralib Project [3]. They have developed an integrated suite of server and framework tools for developing integrated applications based around the use of imagery and the management of imagery within a database (Postgres from memory). I'm not doing them justice with this brief description. They have done some very impressive work. I'd recommend Gilberto Camara's intro paper at [4] for an overview of Terralib. ======= [1] http://www.rasdaman.org/ [2] www.earthlook.org [3] http://www.terralib.org/index.php [4] http://www.terralib.org/docs/papers/TerraLib-OSBook-versionJanuary2008.pdf Bruce Bannerman ________________________________________ From: discuss-boun...@lists.osgeo.org [discuss-boun...@lists.osgeo.org] On Behalf Of Mike Toews [mwto...@gmail.com] Sent: Tuesday, 4 May 2010 6:11 AM To: discuss@lists.osgeo.org Subject: [OSGeo-Discuss] Raster catalog ideas Hi All, I'm wondering what existing open source options are available to store rasters with attributes. For example, I have several hundred air photos from northern Canada spanning from the 1940s to now. They have different projections (UTM zones), cell sizes, etc. This data store needs to be accessed from both web and desktop GIS software, but needs to have a definition query for the "year" attribute (so I can take all air photos from 1962, or between 1973 to 1978, or whatever is required). Our (my company) present solution is to use ESRI's raster catalog on a geodatabase. We've had a mixed range of problems on File/Personal/SDE Geodatabases. We've experienced corruption on all levels of storage options, so we keep our file path attributes to the original GeoTIFFs so the raster catalogs can be restored, if required. I'm a bit lost for the available options. The future PostGIS with raster capabilities sounds promising, but I need something that already exists. I don't think a WMS service will work, since it cannot use a query definition (e.g., I don't want to make layers for each year). What are other people doing for large stores of air photos? Thanks in advance. -Mike _______________________________________________ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss
