Bachelor level course in Physical Geography at Marburg University
Monitoring biodiversity and its change through space and time is a key challenge for ecogeographical research. Linking up-to-date remote sensing data with machine learning has been shown to be a powerful complementation of labor-intensive field work in order to derive area-wide biodiversity indices, which also capture larger spatiotemporal scales.
Using LiDAR and Sentinel data as example, this course will be a foundation for acquiring, managing, and modelling different types of geodata and will provide a solid baseline for workflow automation with remote sensing data in R.
Intended learning outcomes
At the end of this course you should be able to
- feel comfortable with the usage of R,
- know the basics of remote sensing theory and machine learning,
- handle LiDAR and Sentinel data,
- use random forest for spatial predictions,
- include and process different types of remote sensing data in a single workflow, and
- apply all of the above to a real-world example.
Course features
This course runs on a weekly basis (Mondays, 14:15 - 15:45, starting 21.10.2024). Course units will consist of one topic (see table below), different ways of their practical application in R and an exercise for applying your new skills. The topics will be presented as online readers, screencasts, videos or collections of blog posts and examples of other researchers. You can do the exercises at your own pace and we will discuss them in the subsequent session.
Organizational matters and further details can be found here and will be discussed during our first kick-off session.

Deliverables
The graded course certificate will be based on an individual assignment (“Hausarbeit”), which builds upon the processing workflow established during the course.
Preparation and prerequisites
Basic knowledge of R and of handling spatial data is beneficial, but not required.
