1 Different ways to use GIS Eva Grum Tu-Vienna Institut for Geoinformation

2 Grum Eva Tu-Vienna Institute for Geoinformation Forschungsseminar Overview What are Geographic Information Systems? Pyramid of costs Layers Different kind of Data Where can you use GIS? Why use GIS?

3 Grum Eva Tu-Vienna Institute for Geoinformation 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.

4 Grum Eva Tu-Vienna Institute for Geoinformation Forschungsseminar Pyramid of costs

5 Grum Eva Tu-Vienna Institute for Geoinformation 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 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.

7 Grum Eva Tu-Vienna Institute for Geoinformation Forschungsseminar Where can you use GIS? 1/5 Landscape-information-systems: Multi purpose cadastre Topographical information system

8 Grum Eva Tu-Vienna Institute for Geoinformation Forschungsseminar Cadastral map This is a cadastral map where it is possible to find different features: -parcels, -streets, -houses and -some other information about sewerage systems.

9 Grum Eva Tu-Vienna Institute for Geoinformation Forschungsseminar 3D Model of a landscape In this model there are only the base data for a 3D digital terrain model given.

10 Grum Eva Tu-Vienna Institute for Geoinformation Forschungsseminar 3D Model of a mountain Here are the base data and some additional data about the geology.

11 Grum Eva Tu-Vienna Institute for Geoinformation Forschungsseminar Where can you use GIS? 2/5 Spatial-information-systems Regional planning and topographical planning Municipal application Landscape planning Official statistics

12 Grum Eva Tu-Vienna Institute for Geoinformation Forschungsseminar Statistics School boundaries with statistical information.

13 Grum Eva Tu-Vienna Institute for Geoinformation Forschungsseminar Where can you use GIS? 3/5 Environment-information-systems International environment programs National environment programs Landscape-ecological application Agriculture and forestry Internal environment-information-system

14 Grum Eva Tu-Vienna Institute for Geoinformation Forschungsseminar Agriculture An example for statistics and forestry.

15 Grum Eva Tu-Vienna Institute for Geoinformation Forschungsseminar 3D map versus a 2D map This map shows a part of a national park in two different views.

16 Grum Eva Tu-Vienna Institute for Geoinformation Forschungsseminar Catastrophic risk in the United States Here the risk zones for hurricanes, earthquakes, tornados, and hailstorms are shown.

17 Grum Eva Tu-Vienna Institute for Geoinformation Forschungsseminar Where can you use GIS? 4/5 Network-information-systems General requirement Examples for Network-information- systems

18 Grum Eva Tu-Vienna Institute for Geoinformation Forschungsseminar Waterways An example for the waterways and gullies.

19 Grum Eva Tu-Vienna Institute for Geoinformation Forschungsseminar Electricity Shows the electric mains.

20 Grum Eva Tu-Vienna Institute for Geoinformation Forschungsseminar Where can you use GIS? 5/5 Specialty-information-system GIS in transport and traffic GIS in business-area GIS in social-area GIS in national defence GIS in telecommunication GIS in resource-management Other GIS applications

21 Grum Eva Tu-Vienna Institute for Geoinformation Forschungsseminar Transportation: The air transportation becomes more important. This is the status of air routes from Japan to Asia.

22 Grum Eva Tu-Vienna Institute for Geoinformation Forschungsseminar Telecommunication: Areas with a strong enough signal to use the wireless network demonstrated in a 2D model.

23 Grum Eva Tu-Vienna Institute for Geoinformation Forschungsseminar Telecommunication: Areas with a strong enough signal to use the wireless network demonstrated in a 3D model.

24 Grum Eva Tu-Vienna Institute for Geoinformation Forschungsseminar Navigation: Pedestrian and bicycle navigation considered as example from Atlanta.

25 Grum Eva Tu-Vienna Institute for Geoinformation Forschungsseminar Routing planner: from Bregenz to Eisenstadt

26 Grum Eva Tu-Vienna Institute for Geoinformation Forschungsseminar The result of the query

27 Grum Eva Tu-Vienna Institute for Geoinformation Forschungsseminar Search for an exact address: Stephansplatz 1

28 Grum Eva Tu-Vienna Institute for Geoinformation Forschungsseminar The result of the query

29 Grum Eva Tu-Vienna Institute for Geoinformation 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 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 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.
