Here you find all information needed to structure your studies with a focus on Earth Observation: course descriptions, potential topics for your bachelor or master thesis, and good practice examples of theses or MAPs from previous courses.


burned area - distroyed buildings with brown gras area in front in KazakhstanLandsat reveals a sevenfold increase in burned area caused by land-use change in Kazakhstan

Dissolution of the Soviet Union resulted in an unprecedented cropland and grazing abandonment. In our latest research we detected a dramatic intensification of fire regimes since 1990 in northern Kazakhstan using Landsat imagery. This change can be attributed to crop residue burning and agricultural abandonment.

map piece showing classes of cropping practices for Turkey.Good practices for large-area cropland mapping

We paired open access algorithms with intra-annual Landsat time series to produce a national-scale map of cropping practices for Turkey. Read the paper and download the map product. You can explore the map here.


pan-European land cover map from Landsat data and LUCAS field surveyNew pan-European land cover map

Using Landsat data and the LUCAS field survey, we developed the first pan-European land cover map for the year 2015. Find out more how we did it here, explore the map here, or download the entire dataset here.


sea rubber conversion - landscape fotoCambodia's tropical forests give way to rubber tree plantations

Using satellite imagery, we show the impact of rubber tree plantations on Cambodian forest cover and analyse how annual forest-to-rubber conversion rates relate to global rubber prices from 2001 to 2015. Find out our more here and here.

shrubland in southern PortugalCharacterizing shrubland dynamics in southern Portugal

We show how a 32-year time-series of annual shrub fractions can be derived from Landsat data covering a (semi-)natural ecosystem in southern Portugal. The time-series depicts relevant shrub-related change and management processes like gradual encroachment or cyclic clearing & regrowth. Find out our more here.

mix of urban compositions across multiple cities - satellite imagery analysisHow pixel quality flags affect the availability of analysis ready data

Analysis ready data relies on pixel quality flags informing about sensor saturation and clouds. But what happens if your cloud screening algorithm detects clouds frequently because it can’t handle specific surface types/conditions? And how does sensor saturation over bright targets impact on observation density? To find out we analyzed more than 30 years of Landsat data in collaboration with Geoscience Australia. Find the results here.
