Eye4Software Hydromagic

Eye4Software Hydromagic is a Hydrographic Surveying software product. It is used by survey, mining and dredging companies all over the world to perform hydrographic surveys in rivers, oceans, ponds and reservoirs. Using a positioning system like a GPS or RTK receiver, together with a hydrographic echosounder, position and depth data is recorded.

The collected raw data can be post processed and used to generate volume reports, depth maps, depth contour maps and much more. The development of Hydromagic has started in 2001 and is sold worldwide since 2011.
