As part of an ongoing contract with the U.S. Army Corps of Engineers, Degrove Surveyors recently completed a series of hydrographic surveys supporting U.S. Coast Guard Navigation Projects. The project included surveys of six navigation channels along Florida’s west coast, including: Steinhatchee River, Withlacoochee River, Homosassa River, Cedar Keys Harbor, Crystal River, and Keaton Beach.
The project entailed the single-beam survey of profile lines along the centerline of each navigation channel, as well as the channel edges in some cases. Navigation aids (channel markers) were also located, photographed, and included on the map. The total length of lines surveyed on these six channels was approximately 80 miles, with over 250 navigation aids located. The surveys were completed on the location-dependent datum of Mean Lower Low Water (as per project requirements). Degrove utilized RTK GPS for horizontal and vertical positioning of the vessel. The survey was completed and processed using Hypack software.
