PILOT PROJECT ON A LAND USE/LAND COVER DATABASE IN THE AREZZO PROVINCE (TUSCANY, ITALY)

摘要

ISTAT, the National Institute of Statistics in Italy, promoted in 1998 a pilot project for the realisation of a land use/ land cover database at 1:25,000 scale over a test area in the Province of Arezzo, 2000 km~(2) wide. The aim of the project was to assess the feasibility of a methodology for the development of a land use/land cover database which could become a component of the ISTAT geographical information system. The legend, derived from Corine Land Cover, was composed by 5 levels. The methodology of interpretation is based on the integrated use of multitemporal TM imagery, ortho-photos and auxiliary data. The sample design of the Forest Area Frame is based on a stratification derived from the 3rd level of the Corine legend and Digital Terrain Model. Ground truth from 140 sites, positioned by GPS, was collected. The project was carried out by RSDE, DREAM and GEOS.
