UMUS: A DEMONSTRATION PROJECT FOR USAGE OF LANDSAT MSS AND ANCILLARY DATA IN LAND COVER MAPPING OF LARGE AREAS IN SOUTHERN ITALY.

Considerations is given to problems related to producing a land use map at 1:200,000 scale and at a I-II level by using Landsat MSS data in a geographical context characterized by spatially complex vegetation and terrain. The set-up procedure is based on the integration of multitemporal satellite images with conventional data (digital terrain model, aerial photos and existing agricultural inventory data). Emphasis is given to the aspects of management of the integrated data set, the method for sample areas selection and on the use of prior probabilities in the classification process. The final map is presented and its accuracy quoted.
