QGIS supports a number of raster and vector data formats, with new support easily added using the plugin architecture. Supported formats are : - spatially-enabled PostgreSQL tables using PostGIS. - most vector formats supported by the OGR library, including ESRI shapefiles, MapInfo, SDTS and GML. - raster formats supported by the GDAL library, such as digital elevation models, aerial photography or landsat imagery. - online spatial data served as OGC-compliant WMS or WFS. |

| pgrouting-3.6.2 | geospatial routing extension for PostgreSQL | pgRouting extends the PostGIS / PostgreSQL geospatial database to provide geospatial routing functionality. Advantages of the database routing approach are: * Data and attributes can be modified by many clients, like QGIS and uDig through JDBC, ODBC, or directly using Pl/pgSQL. The clients can either be PCs or mobile devices. * Data changes can be reflected instantaneously through the routing engine. There is no need for precalculation. * The "cost" parameter can be dynamically calculated through SQL and its value can come from multiple fields or tables. |
