5. Conclusions
It could be concluded that the creation of land resources database is rather important in documenting the
environmental themes. Such documentation leads to data harmonization and maximization of its value. It
also allows an easy data processing, and updating. The land resources databases are rather useful in
elaborating site selection for sustainable development projects, in addition to decision support and early
warning.
Remote sensing, with its multi-concept approach, provides up-to-date information on different themes.
Multi-dates images allow detecting the changes occurring in the different environmental conditions. Also,
the multi spectral satellite images reflect the environmental elements characterized by a variety of spectral
signature. Moreover, GIS and its integrated functional nature with remote sensing, facilitate the creation and
developing land resources databases.
