Download and Install quantum GIS – QGIS with oracle connectivity. Quantum GIS is an open source cross platform software for developing GIS (Geographic information System) solutions. QGIS connects to large set of spatial database and supports many data file formats, which enable us to visualize data, analyze data, edit data and generate a final map. QGIS is a best alternative to ESRI ARCGIS Desktop and is available for free under GNU General Public License. You can download and install Quantum GIS from either of the two way, i.e by standalone installer software or you can install it with OSGeo4w installer. OSGeo stands for open source geospatial foundation which include many open source projects, geospatial libraries, desktop application and web mapping.
While QGIS can be installed by one click with QGIS standalone installer, but it is better to install QGIS with OSGeo4w software as it helps you to install many libraries and packages with QGIS. As this post topic is concentrating for QGIS with oracle connectivity, so, for that reason we need to install GDAL/ORG library with QGIS , and it would be easy for you to install with support of OSGeo4w installer.
