Hi Alek, I can simply add few more details to your already excellent introduction. SpatiaLite is a loadable extension adding standard Spatial SQL capabilities to the SQLite's basic core. It's almost conformant to OGC-SFS [1] and ISO SQL/MM-Spatial international standards for Spatial DBMSes and Spatial SQL; roughly speaking it offers a sound and powerful light-weight alternative to the much more complex PostgreSQL/PostGIS client-server Spatial DBMS. It's certainly interesting to note that SpatiaLite has been successfully ported on Android and other mobile or embedded devices. directly included in SpatiaLite are several Virtual Tables implementing the following features: - VirtualText: direct read access by SQL to external CSV and structured text files - VirtualDbf: direct read access by SQL to external DBF files - VirtualXls: direct read access by SQL to external MS XLS spreadsheets (old Excel binary format) - VirtualShape: direct read access by SQL to external ESRI Shapefiles (the de facto standard exchange format for Geographic vector data) - VirtualSpatialIndex: full fledged Spatial Index support based on R*Trees - VirtualNetwork: pure SQL Routing based on a road network (aka graph) [Dijkstra's Shortest Path] - VirtualXPath: standard XML Path Language a further self-standing loadable extension closely related to SpatiaLite is VirtualPG, allowing to establish a client connection to a PostgreSQL/PostGIS server and then supporting direct data exchange between the two DBMSes by standard SQL statements. both SpatiaLite and VirtualPG are released under the MPL "tri-licence"; you can freely choose you best fit license between the GPL, LGPL or the MPL itself. bye Sandro [1] http://portal.opengeospatial.org/files/?artifact_id=25355 _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
