Title Geographical positioning using laser optical instrument for near-shore underwater archaeological explorations
 
Creator Ganesan, P.
 
Description Underwater archaeological explorations, which are being carried out both in shallow as well as in deep waters, need accurate positioning system for locating any artifacts and to plot on suitable scales. Even though surveying has a well establish procedure, but being underwater, it has it's own difficulty. Several conventional methods and instruments are available for obtaining underwater positions in shallow water areas. The main objective of this paper is to introducing a new technique of measuring angles and distances using laser optical instrument from the shore to obtain accurate underwater positions. The prescribed method can be applied effectively for all shallow water archaeological surveys. Under calm sea condition this method can be applied up to a water depth of 10 meters and with a coverage limit of about 5 to 6 kms from the shore, under calm sea conditions.
