QGIS is a user friendly Geographic Information System that lets you view and manipulate spatial data on your computer. It supports many common spatial data formats (e.g. PostGIS, ShapeFile and geotiff). The installation of QGIS from sources can result strongly different depending on the optional/required packages installed and enabled. This slackbuild is based on basic and some optional settings that require the dependencies (and related nested deps) reported in the REQUIRES field of qgis.info. For further information see the README.Slackware file.
