[8] In 2013, along with release of version 2.0 the name was officially changed from Quantum GIS to QGIS to avoid confusion as both names had been used in parallel. [9] Written mainly in C++, QGIS makes extensive use of the Qt library. [6] In addition to Qt, required dependencies of QGIS include GEOS and ...
QGis (full name: Quantum GIS) is a GPL license, cross-platform (Windows, Linux, Mac), and rather friendly cartographic software application. It is a Geographic Information System (GIS) program you can use to create, view, and analyze maps.
This is a comparison of notable GIS software. To be included on this list, the software must have a linked existing article. The selection of GIS software is a non-trivial task typically undertaken at project commencement. The use of appropriate selection criteria and methodology can be critical to a project's success, with considerations including outlay costs, ease of use, data and system ...

The key idea is to use the bounding boxes to decide whether or not to search inside a subtree. In this way, most of the nodes in the tree are never read during a search. Like B-trees, R-trees are suitable for large data sets and databases , where nodes can be paged to memory when needed, and the whole tree cannot be kept in main memory.
Georeferencing or georegistration is a type of coordinate transformation that binds a digital raster image or vector database that represents a geographic space (usually a scanned map or aerial photograph) to a spatial reference system, thus locating the digital data in the real world.
