Hydrography focuses on measurements of physical characteristics on and in the water. These characteristics can be used for many purposes. For navigation and harbour management the navigational depths, objects, tidals and currents are determined for safe navigation. In coastal management hydrography can be used for monitoring the near shore seafloor and the ecological systems. For dredging activities they can be used for equipment/vessel planning, determining quantities and project management.
Geodesy can be explained as hydrography with the difference that geodesy focuses on measurements above sea level. The measurements are conducted with high-tech equipment such as latest GPS-techniques (GNSS, RTK), echosounders (dual frequency for silt layers and multibeam for wide path measurements up to 2.5 times the local waterdepth), motionsensors and so on.
Aquifer Consultancy performs hydrographic surveys such as single-, dual- and multibeam. We are equipped with 2 Reson Seabat 7101 multibeam echosounders and various singlebeam echosounders single or dual frequent. We can produce charts for harbour- and shore maintenance, harbour- and off-shore constructions, monitoring dredging and/or dumping activities. We can produce data exchange for customers who prefer their own charting and data processing. We build, calibrate and maintain automation devices for dredging or dumping activities.
