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.

Layers
A GIS stores
data about
the world as a
collection of themed
layers that can be
used together.

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.

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.

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.

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.

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.
