This course takes 3 days with 8 hours each (on site) or 5 hours each (online).
The only difference is that there will be less practical exercises in an online course. However, we will hand them over to you and you can still do them on your own and ask our consultants for feedback or help if needed.

This GIS course enables participants to identify potentials of spatial data and to put them to use.

Theoretical essentials in geoinformatics form the foundation, in order to gain a broad understanding of the subject matter. The second part brings import, visualisation and analysis of geodata, using OpenSource-tools, into focus. The used data will primarily come from OpenStreetMap.

This course can be held in English and German.

Theoretical part

Applications

What is spatial data and how can you use it?
Getting started with the world of geoinformatics and its applications

Spatial modelling

• Coordinate systems – what are they good for and what do you need to keep in mind when it comes to data acquisition?
  An overview of geographical and projected coordinate systems
• Topology
• Vector versus raster data

Spatial indexing
Spatial data should also be indexed, in order to ensure data quality and performance. Spatial indexing algorithms will be presented.

Spatial analysis

Which analyses can be made, and which questions can be answered by use of GIS?

GIS-tools
How is spatial data processed?
An overview of popular tools, focusing on OpenSource.

GIS-Services
What kind of spatial services do exist and are of special interest for companies?

• Mapping
• Routing
• Geocoding
