The Potential for Earth Observation for the Analysis of Land Surface Dynamics

 

At present an unrivalled amount of remotely sensed earth observation data is globally available in satellite data archives. Imagery from medium-, high- and highest resolution optical, multispectral, and radar sensors is waiting to be exploited to reveal its full potential. The USA and Europe have set the pace in sharing earth observation resources; amongst others via the free and open Landsat data archives spanning nearly four decades, as well as data of the novel European Sentinel missions in orbit since 2014. Along with this go increasing capabilities to handle and explore big data of dense temporal coverage. Comprehensive geographic analyses combining the findings of earth observation data analyses with ancillary data and in-situ ground knowledge impel earth observation beyond simple mapping activities. Whereas in past decades remote sensing data were analysed based on the spectral-reflectance-defined ‘finger print’ of individual surfaces, it is now the ‘temporal fingerprints’ of our land surface which open up novel pathways of data analyses.

Nowadays – more than ever – remote sensing as a methodological discipline can contribute to addressing society-relevant challenges. Especially in highly dynamic regions earth observation can support the sustainable management of natural resources via long-term monitoring schemes and the provision of sophisticated, planning-relevant information. The talk will present related examples from recent analyses of land surface dynamics globally; amongst others addressing food security related land use change in the coastal zone.
