Mediterranean and Iberian flora and fauna

The 'Tenuta di Castelporziano' (Castelporziano Presidential Estate) is an important area for the study of Mediterranean coastal and dune ecosystems. The need of providing a new and detailed Vegetation Map rose for the environmental monitoring of that area and its efficient management. All activities were developed using remote sensing images acquired by a new 12 band DAEDALUS sensor, in the course of a specific monitoring aero-campaign organized by ENEA. The realization of the map, lasted one year, can be divided into two blocks: (1)remote sensing image processing methodologies, developed at the ENEA-Casaccia Research Center (Rome), by experts of Remote Sensing Department; and (2) 'in situ' work, realized by ecologists and botanical experts of University of Rome 'La Sapienza'. Image processing steps were organized as follows: (i) geometric correction and georeferencing of the images; (ii) classification; (iii) mosaicking; (iv) conversion into vector layer and editing. As concerns image processing, ERDAS/IMAGINE system was used, while ARC/INFO system was used for vector layers management and map printing. At the end of all activities the map accuracy was tested by a statistical procedure: the global accuracy was about of 88%. The map is integrated in a information system (SITAC), a GIS realized by ENEA.
