Hydrography is the mapping and characterization of submerged land surfaces. With the advent of high-accuracy GPS survey equipment, and advancements in depth-sounder and data integration software in the 1990's, Wilson developed new methods for performing bathymetric surveys to establish submerged surface elevations. As a variety of sensors such as side-scan sonar, multi-beam bathymetric scanners, and sub-bottom profilers became viable consumer-grade technologies, Wilson expanded its skill base to provide richer surface, and sub-surface, data.
