7. a GIS is not simply a mapping program The main advantage of using a GIS and not a simple graphics program is the possibility to give a certain object a variety of attributes By selecting this object all attributes become visible Furthermore the ability to analyse and manipulate data exists The queries below can all be answered with GIS functionalitv e What river is longer than 100 km e How many buildings are closer to a lake than to a mountain e What city is built on a hill that is higher than 500 meters above sea level Adding to this data can be altered by applying a manipulation functionality Examples are listed below e Erase all regions that are smaller than 2 km e Create a buffer around all rivers It is apparent that GIS are not only used in classical surveying or cadastral tasks They are nowadays used in infrastructure or recycling offices geological agencies tourist informations and many more Examples for such geographical information systems are ArcGIS Geomedia or QGIS QGIS Mapserver 1 Basics 1 2 1 Data formats Geospatial data can be stored in two different wavs vector data or raster data Vector Data Vector data can be explained with various objects that fill an emptv space These objects can be points lines or polygons and can hold any number of attributes An example for the use of such a data structure is a dataset which contains the geometrical place of buildings Brovelli 2008 There are three bas
