Master level course in Physical Geography at Marburg University

Data analysis is a key competence for professional geographers that requires profound knowledge in both (statistical) analysis methods and computer sciences. While the reason for the former is obvious, the latter is a direct result of a growing data deluge, induced by technological progress on both the fields of data collection and distribution.

Data analysis is based on a variety of skills related to organizing, handling, describing and understanding a diversity of datasets. By using the programming environment R, this course will not just open the door to a cosmos of data analysis functionality but will moreover provide a domain specific and flexible tool for workflow automation.

Intended learning outcomes

At the end of this course you should be able to

  • organize a variety of datasets and (intermediate) analysis results in structured fashion,
  • document your workflow in an understandable and transparent manner, collaborate in teams and handle issues and task management using Git and GitHub as software management tool and platform,
  • implement data analysis workflows using tailored R scripts along with readily available functions from third-party R packages,
  • model relationships between data variables and calculate reliable error estimates, and to
  • critically evaluate your analysis.

Course features

The course provides a basis for the parallel Geo Information Systems and Remote Sensing courses. It is intended as a blended learning module in our study program although the provided introductions, explanations and examples might be useful for self-study, too.
