The project aims at establishing a 1-km pan-European land cover database that can be updated frequently. The database will be based on the integrative use of multispectral and multitemporal 1-km resolution NOAA-AVHRR satellite data and ancillary data. PELCOM is a three years project accepted as a shared cost action under the Environment & Climate section of the European Union's 4th framework RTD programme. The project started in September 1996 and is carried out within an international framework, in which the DLO Winand Staring Centre functions as the project co-ordinator.
