Bathymetric Survey & Design Experience

At G. M. Selby, Inc., the engineers and surveyors are equipped with the latest tools in the profession which enable them to produce the most accurate designs and construction methodologies.

We acquire satellite imagery that is rectified using DEM’s to produce up to date site conditions. Our engineers use these images to produce efficient designs for dredging, site preparation, dredge fills, and roadway designs.

Our teams use the latest Differential Global Positioning Systems (DGPS) equipment, Sonar depth echo-sounders, computers, and hydrographic software packages. This equipment, combined with our experience, yields quality designs that are delivered in a timely fashion to satisfy your infrastructure needs.
