Tracking of the LAZIO region shoreline from orthophotos AGEA 2014 and implementation of the database layer
The integrated coastal zone management (ICZM) is the modern approach used in the study, management and exploitation of the coastal area in various applications whereas in this area are concentrated interests concerning the most different fields, economic, environmental, legal, scientific and social. The coast is in fact inherently unstable by nature and consequently its characterization should take into account a continuous monitoring and updating of its variations and trends. The coastal area is that portion of land emerged and submerged containing the shoreline and is subject to both continental and marine geomorphic processes. The shoreline is the clearest expression of how this sector is particularly dynamic. Proper analysis and representation of the shape and nature of the coastal area are a first step to provide reliable and comparable tools to those who study and manage it. This paper presents the results of a study aimed to the realization of an integrated approach in the extraction of the shoreline using a case study of Lazio coast as a part of the European Project “Intercoast”.
This work is based on national and international directives on the coastal zone, whether linked to a more terrestrial or maritime area, still within the broad definition of Hydrography provided by the International Hydrographic Organization (IHO).
The spatial information extracted by direct or indirect measurements of the most dynamic coastal sector emerged and submerged (emerged coast and sea bottom) have been provided by associating with a budget of measurement uncertainties, and assessing the quality.
