Definition
In hydrographic SURVEYING, a TRIANGULATION that may be carried out by means of anchored BUOYS when surveying at such a distance from the LAND that the SIGNALS on the SHORE cannot be directly used for locating the SOUNDINGS. Floating triangulation can be either connected to and extended from the STATIONS of a shore triangulation or of a fully floating type in which case the POSITIONS of the BUOYS are obtained by means of OBSERVATIONS and measurements taken at sea. BUOYS are anchored in such a position as to provide a framework for surveying the area.
