Résumé :
|
Four weeks of field work have been performed, allowing to collect a data base in support of the remote sensing mapping of the coffee wilt disease in three sites in Uganda. These sites are coffee growing areas of about 15 x 10 km in dimensions, located respectively near Mukono, Kiganda (Mubende district), and Kyenjojo. This set of data includes ground truth information records on crops and landscape, and on coffee trees architecture and sanitary status, leaf area index and crops spectral properties measurements. The work was focused on the Mukono site, selected as the training site for remote sensing tools development. For this area, a large amount of records in a large range of variability have been managed, a little less for the two others. At the same time, Borstad and Associates attempted several flybys over the sites in order to acquire CASI hyperspectral images. Due to bad weather conditions, only Kiganda and Mukono sites have been shot at the end.
