Uncorrected and across-track brightness corrected image mosaic of the San Francisco Bay AreaHow to correct for brightness gradients in hyperspectral image mosaics

We produced an analysis ready EnMAP image for regional-scale mapping in the SF Bay Area. Secondary geometric alignment and brightness gradient correction were applied to multiple AVIRIS flightlines simulated to resemble spaceborne acquisitions, yielding high quality hyperspectral mosaics.

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.
