To make it easier to contribute to QGIS, the team has created a clone of the Subversion repository on GitHub. Using GitHub makes it easy to submit enhancements and bug fixes for inclusion in the Subversion repository. Gary Sherman describes the process in his post “Contributing to QGIS Using Git”.
Another of Gary’s projects is available via GitHub too: GeoApt Spatial Data Browser. It’s a data browser written in Python using QGIS bindings. It allows navigating a tree structure and previewing raster and vector datasets and associated metadata. Another nice feature: It supports drag & drop to e.g. QGIS! The project homepage can be found at: geoapt.com.
