The basic aim is to study the "behavior" of coastal areas by devising a special indicator to model human intervention in coastal zones and the surrounding areas. Detail of aerial photo draped on the AIEM Applying the indicator an increase in the year 2007 is apparent : a2007 = 5,72 m. On the contrary in 1985 the human impact was less: a1985 = 4,55 m. Thus, within 22 years the indicator of the human intervention has been increased around 1,17 m.

Differences Among the areas that occupy the same land use in different time periods are noticed. The images were digitized and produced the land use maps (Length > 10km, Width ~ 3km from the coastline) There were created totally 16 Land Uses in polygon layers. After the digitization the Land Uses were compared in two different time periods. “Anthropogenetic Intensity Anthropogenetic Intensity” si : the area of each land use hi : the real height of each land use construction wi : weight for each land use This indicator has been proposed by: Kiousopoulos 1999, Kiousopoulos & Lagkas 2005, Kiousopoulos 2007 ¦ ¦ i i i i s w h s ai 1985 2007 a2007 2007 = 5,7 5,72 m 2 m a1985 1985 = 4,55 m = 4,55 m 2007 1985 ) ( * d f s w h s ai i i i i ¦ ¦ Each land use has a different weight proportionally analogous to its distance from the shoreline. For example, one land use close to the shoreline (within 1 km) will not have the same weight like one farther away (10 km). In each coastal area all the factors that can influence the change of land use & cover have to be considered. The weights are related mainly to the extent of the construction volume, the distance from the shoreline and other parameters. Depending on the land use and its real height hi, each land use has a distinct weight wi which has been evaluated arbitrarily. Some of these uses do not exist in 2007 compared to 1985 (e.g. Trees in the form of a Forest). On the other hand some others occupy a bigger extent of area in 2007, because of the human intervention (e.g. There is an increase in Urban Fabric Areas, Tourism, Transport.) By mapping the human impact in coastal zones, it is possible to measure the human intervention in those areas, with the Anthropogenetic Inten
