The aerial imagery has a long tradition of use as a surveying method in underwater archaeology. With the recent development of new technologies, its application has become more versatile and more common. This article will present the use of aerial photogrammetry in the archaeological survey of the submerged heritage of Nessebar, ancient Mesambria, on the Bulgarian Black Sea coast. A major application is the generation of a digital bathymetric model (DBM) of the seafloor, which is reliable and accurate approximately up to -- m depth. It is especially useful in shallow waters and in the intertidal zone, where the implementation of multibeam echosounder scanning is not possible. The combined photogrammetry and multibeam echosounder data generate a precise and accurate surface model of the Nessebar peninsula and its adjacent aquatory with satisfactory resolution (25 cm raster for the seafloor) up to -18 m depth. Another major application is the production of orthophotomosaic (OM) with high resolution (5 cm raster). Both techniques have been used for the creation of multilayer GIS database, documentation and mapping of the archaeological structures and their environment, surveying for unknown archaeological sites, virtual reconstruction of the paleolandscape and its evolution. Important advantages of the aerial photogrammetry is its economic application, fast and logistically easy field data acquisition, relatively fast data processing and low-budget equipment.
