Geodesy and Geoinformation: What's that?


Geo Information Systems (GIS)

Geo Information Systems (GIS) are computer-aided instruments for capturing, storing, analysing and displaying data which are spatially referenced to the Earth. At the first glance GIS have a lot in common with traditional (analogue) maps and with modern web-based Earth-Viewers.

GIS Applikation im Earth Viewer
The GIS principle: view on „intelligent“ Geo Data in a widely used Earth Viewer.

But with GIS you can do much more! One of the main features of a GIS is combination of various spatially referenced geometries with non-spatial information, which in turns allows multiple analyses: GIS analyses enable a town to manage their housing stock more adequately, retail firms may find proper locations for branch offices, fire fighters or police forces may be provided with efficient support in case of a disaster.

Other fields of application are:

• surveying

• utilities

• planning

• nature conservation

• agriculture

• navigation

• aviation and aeronautics

• telecommunication

• location based services

GIS have been well-established in multiple sectors of the economy within the past decades and the ongoing growth of the geoinformation-market led to an increasing demand for specialists in GIS.

Profound GIS knowledge can only be provided by a suitable education, which is offered e.g. by academic studies in Geodesy.
