Cartography and GIS
Research activities of the CGIS group focus on:
Monitoring of the urban environment
An important part of the research activities in the CGIS group focus on the use of remote sensing and GIS-driven approaches for monitoring the urban environment, mostly in the context of urban ecosystem analysis and urban sustainability studies. Special attention in this research goes to the use of knowledge-based methods and machine learning approaches for image interpretation, relying on spectral, textural as well as contextual information. Recent work focuses on hyperspectral remote sensing of urban areas, using airborne data, as well as on multi-scale multi-sensor mapping approaches.
Geospatial analysis of the urban ecosystem
Research activities on geospatial analysis of the urban environment includes monitoring and modelling of urban sprawl, monitoring of urban green(ing), participatory research on use and valuation of public green spaces and nature based solutions, impact of urban dynamics on urban ecosystem services, urban quality-of-life assessment. The group also considers a social equity and environmental justice perspective in the analysis of these urban ecosystems components. Developing remote sensing and GIS-driven modelling approaches in support of local and regional decision making is an important concern in much of the work done by the lab.
Remote sensing of natural hazards
Through the FED-tWIN project “GUIDANCE” (long term collaboration with the Royal Museum for Central Africa), CGIS recently started up a new research line focusing on the study of geohazards in Africa. The main objectives are to better understand the physical processes underlying natural hazards and gain insight into baseline patterns/rates of these hazards in an urban sprawl context, using Synthetic Aperture Radar (SAR) remote sensing and SAR interferometry (InSAR), Structure-from-Motion (SfM) photogrammetry, optical remote sensing and UAV-based image acquisition.
