Lesson 9. Land cover mapping
Land cover data is required for conservation, land resource planning, and studies of biodiversity and environmental change. The only feasible way of obtaining such information for large areas over several years is with satellites. However, obtaining data of sufficient accuracy is not always straightforward. Results may vary depending on sensor characteristics and classification methods. This lesson shows how to obtain land cover information form multi and hyperspectral data at different spatial resolution, and teaches the basics of land-cover data validation. It also looks at the possibility of obtaining extra information by using sensors that look at a location from several viewing angles.
