  3. Land-use classification schemes typically address both land use and land cover. A major land-use classification system developed by the United States Geological Survey (USGS) has multiple levels of classification. The categories within these levels are arranged in a nested hierarchy.

  4. natural terrestrial cover is classified by the United Nations Educational, Scientific, and Cultural Organization (UNESCO, 1973) system (as modified for the United States by Driscoll and others (1983, 1984) and by this bulletin, see below); natural aquatic cover is classified by the system of Cowardin and others (1979); and.

    The CORINE Land Cover update to the year 2000 (CLC2000), called Image and Corine Land Cover 2000 project (I&CLC2000), schedules the acquisition of remotely sensed Landsat 7 ETM+ images (Image 2000), the production of the geographical database of land cover for the year 2000 and the assessment of the land cover/land use changes between the years 199...

    The implementation of CLC2006 focuses mainly on the identification and mapping of land cover changes between 2000 and 2006. CLC2006 is scheduled as a direct continuation of previous Corine land cover mapping campaigns. Land cover changes larger than 5 ha must be mapped, regardless of location. As in previous years, the work is a shared approach bet...

    The Corine/Land Cover map has been produced for the 27 countries of the European Union. As an example, the case of Italy is presented to clarify the general approach used in Europe. The original interpretation of CORINE/Land Cover for the year 1990 (CLC90) did not have a homogeneous implementation in Italy nor a standardized methodology of realizat...

    The comparison between classification systems based on pre-defined classes highlights the limit of the method for both regional and global applications. Due to excessive rigidity, these classification systems are often limited to defined geographical areas and drawn for a specific kind of application. The systems described present a lack of clearne...

  6. Users not familiar with classical vegetation classification and mapping (Eiten, 1968; UNESCO, 1973; White, 1983; Kuechler and Zonneveld, 1988) or ecological studies should be able to build up a scientifically sound vegetation classification by following the Land Cover Classification System.
