3. Grum Eva Tu-Vienna Institute for Geoinformation 27.01.2004 Forschungsseminar What are Geographic Information Systems? A GIS is a system of hardware, software, data, editors, and users which combines layers of data about a place to give a better understanding of that place.

5. Grum Eva Tu-Vienna Institute for Geoinformation 27.01.2004 Forschungsseminar Layers A GIS stores data about the world as a collection of themed layers that can be used together.

6. Grum Eva Tu-Vienna Institute for Geoinformation 27.01.2004 Forschungsseminar Different kind of Data Raster data: has a geometric base element and this is the raster cell. A raster model consists of many cells. Vector data: comprised points, linear connections between these points and polygons which are framed from such lines.

29. Grum Eva Tu-Vienna Institute for Geoinformation 27.01.2004 Forschungsseminar Why use GIS? 1/3 Improve organizational integration: A GIS can link data sets together by common locational data, such as addresses, which helps departments and agencies share their data. Data can be collected once and used many times.

30. Grum Eva Tu-Vienna Institute for Geoinformation 27.01.2004 Forschungsseminar Why use GIS? 2/3 Make better decisions: better information leads to better decisions: this old adage is true for GIS. For example: finding the right location for a house or a building in a low risk area and near a population center.

31. Grum Eva Tu-Vienna Institute for Geoinformation 27.01.2004 Forschungsseminar Why use GIS? 3/3 Make maps A GIS creates maps from data drawn from databases. Existing maps can be digitized and translated into the GIS as well.
