In order to meet the growing need for environmental protection, management of natural hazards, natural resources conservation and sustainable agriculture imposed by the European Union, the Walloon Region wishes to enrich its database of geographic reference data with the large-scale mapping of impervious surfaces. Additionally, as these impenetrable materials such as asphalt, concrete, brick, and rooftops are considered to be a significant alteration of the quality of the soil as a natural resource (COM 2006, European directive on soil protection), knowing the exact extent of these impervious surfaces is very important. The CASIM project aims at mapping these impervious surfaces herein considering different mapping methodologies. Furthermore, at the same time the value of the existing aerial ortho-images, LIDAR data and different thematic data produced or acquired by the Walloon Government is assessed for mapping these surfaces. In detail, this study involves two tasks: (i) Mapping of impervious surfaces with existing data, managed, produced or acquired by the Public Service of Wallonia, including the land use map of Wallonia, the digital soil map, the PLI, ... (ii) Assessing the feasibility of mapping impervious surfaces in Wallonia with a combination of aerial ortho-photos and LIDAR data. For this a pilot site was selected in the basin of the river Houille. Different methods of segmentation and image classification will be identified and tested.

Created on 7 May 1998 by the Walloon Government, the Standing Conference on Territorial Development (CPDT) is a multidisciplinary research, training and exchange platform that includes about fifty researchers coming from three university Academies (ULB-IGEAT-GESTe ; UCL-CREAT ; ULg-Lepur). The CPDT’s missions are 1. to provide a tool for helping the Walloon Government with its decision-making through research and expertises. 2. to organise an annual inter-university rostrum of the territorial development. 3. to ensure an on-going training, based on active teaching principles, of the Land-use and Town Planning Advisors employed within the Walloon communes. 4. to promote the sharing and dissemination of the research results by means of the website, publications, seminars and conferences.
