Joint Venture Expands Arc’s Advanced Surveying Systems

A new joint venture has been announced between Arc Surveying & Mapping, Inc., Demco NV and OEMG Global to provide geophysical and innovative navigational surveys worldwide.

Arc Surveying & Mapping, Inc, of Jacksonville, Florida and Demco NV of Wintershoven, Belgium have announced a joint venture agreement adding two additional innovative surveying services to Arc Surveying & Mapping, Inc. roster of technologically advanced surveying systems. Under the agreement, Arc Surveying & Mapping, Inc. will offer clients throughout North and South America navigational depth and geophysical surveys utilizing Demco’s Aquares and Rheocable systems. Demco will utilize Arc Surveying & Mapping, Inc. hydrographic services in the Americas.

Aquares is a unique electrical resistivity method developed by Demco NV for marine and fluvial geological exploration. Aquares is in worldwide use by Demco, NV, in Australia by OEMG Global and now in the Americas by Arc Surveying & Mapping, Inc.

Aquares is considered the only existing resistivity method accepted by the worldwide dredging community. For descriptive data click on – click on services – Aquares. To schedule a demonstration or a survey contact John F. Sawyer at

Rheocable is a marine survey method used to accurately determine nautical depths in the presence of fluid mud. The Rheocable method was developed by THV Nautic, consisting of MDCE bvba and Demco NV to cope with current problems and inaccuracies resulting from classical bathymetric dual frequency sounding methods. The principles of the Rheocable are based on locating navigable depths utilizing viscosity rather than the density of fluid mud (commonly referred to as suspended sediments or fluff).
