From 21-23 May about 20 key scientists and practitioners will convene at ITC Enschede, the Netherlands for a three day expert group meeting on slum identification, mapping and monitoring. The experts will discuss methodological issues of slum identification using geo-information technology (Geographic Information Systems and Remote Sensing etc.). This includes monitoring and mapping via very high resolution satellite imagery and geographic information systems.
The need for identification of slum areas is growing rapidly, as the number of slum in cities all over the world is increasing and their quality is deteriorating. At the present time, around one billion people live in slum conditions in the developing world and it is expected that the number will grow up to 1.4 billion in 2020. Yet, the identification of slums is problematic for various reasons:
The focus of the meeting is to document methods for the identification and delineation of slum areas based on very high resolution remote sensing images and supplementary data sets, e.g. census and related GIS data on infrastructure and services. This allows the formulation of a global strategy to collect sufficient and reliable information at the sub-city level and to link that to information at the city level.
The expert group meeting is organised by UN-HABITAT’s Global Urban Observatory/Monitoring Systems Branch, the International Institute for Geo-Information Science and Earth Observation (ITC), The Netherlands and The Center for International Earth Science Information Network (CIESIN), Earth Institute, Columbia University, USA and is partially funded by the Netherlands Ministry of Housing, Spatial Planning and Environment (VROM).
