MAUPP
Description:
MAUPP aims to improve our spatial understanding, prediction and forecast of urbanization and urban population in Africa through the use of remote sensing and spatial modelling. The project addresses two specific objectives:
- Produce an urban expansion model at moderate spatial resolution for African cities. This objective will be achieved through i) using HRRS and VHRRS (both optical and radar) to delineate urban extent of a set of cities, compare the accuracy and limitations of the obtained features and optimize the method based on HRRS, ii) using of the best methods identified using HRRS to generate a database of land cover change to urban over the last 30 years across a large number of cities in Africa, iii) using this database to build urban expansion models, evaluate their forecasting accuracy, and apply them to forecast the future distribution of the major urban extents in Africa.
- Understand and predict intra-urban variations in human population density in Afr
GEPATAR
GEPATAR focuses on the collection of data necessary for future preservation activities. For the majority of Belgian people, the country geologically speaking is more or less safe: no volcano, no major earthquake, and no major landslide. However, neo-ground movements are occurring and they are originated from industrial exploitation of the subsoil, urbanization and (des) industrialization processes, and may also be induced by several local phenomena. Ground movements may significantly affect the buildings and contribute to degradation of their structural stability. GEPATAR will develop tools to explore two large federal archive facilities: the RBINS satellite archive and the KIK-IRPA patrimony heritage data base. Dedicated permanent scattering tool will allow the efficient exploitation of hundreds satellite SAR archive data for ground movement mapping with millimeters accuracy. This risk map will permit a geographical search for selected heritage buildings that might be in risk at the K
