Hydrographic Survey Services

Hydrographic surveys are completed for channels, rivers, reservoirs, lakes, and ocean bays to create topographic images of underwater surfaces.

Hydrographic surveys are performed to map shorelines and bed surfaces beneath a waterway or bodies of water including streams, channels, rivers, reservoirs, lakes, and ocean bays, as well as to establish water depth.

Depth soundings are integrated with GPS positions to generate a digital terrain model (DTM) and contours of the bed and shore. Deliverables include DTM surfaces, thalweg profiles, cross-sections, and water volumes.

Control Point Associates, Inc. owns and operates several types of equipment specific to hydrographic surveying including boats and high-frequency depth sounders coupled with dual-frequency GPS receivers.
