Monitoring land-cover changes in West Africa with SPOT Vegetation: impact of natural disasters in 1998-1999

Primary tabs

Lupo, F. Reginster, I. Lambin, Eric [UCL]

A multi-temporal change-vector algorithm has been applied to SPOT Vegetation data of West Africa over two growing seasons. Change maps displaying the impact on surface attributes of natural disasters such as floods and droughts were produced, based on different vegetation indices and compositing periods. The accuracy assessed on the basis of independent data on natural disasters, was high (76% correct for the NDVI-based map). This land-cover change product provides important information to evaluate the spatial and temporal distribution of rapid changes in land surface attributes.
