The Harbour area corresponds to the vector delimitation, using photointerpretation, of the area occupied by the port infrastructure. The vectorization was based on the orthophotomaps produced by the Regional Secretariat for Science, Technology and Equipment, at 1:5000 scale to the islands of the eastern and central groups and orthoimagery obtained from satellite images on the same scale to the western group. They served to support the vectorization of the ports areas delimitations included in the Integrated Coastal Marine Management plan (POOC).
The orthophotomaps at a scale of 1:5000 of Desertas Islands were made from a digital aerial survey with acquisition of digital photographs with a resolution of 30 cm. The flights were performed between July and September 2010 in three missions.
The delimitation of the Port Jurisdiction Areas covers the land and sea areas, Berths and outside anchorage areas of franchise and trade.
