Bathymetric surveys
Depth maps for ports, lakes, reservoirs and riverbeds.
We measure the bed with the CHCNAV Apache 3 Pro unmanned surface vessel, which carries a single-beam echo sounder and GNSS RTK. For longer distances we use our own inflatable boat with the portable OHMEX SonarMite BTX echo sounder. The autonomous vessel follows pre-programmed lines and enters shallow water that a conventional boat cannot reach, and the data connect directly with the topography of the shore.

- XYZ, DWG and GeoTIFF files
Frequently asked questions
How deep can you measure?
The echo sounder covers everything from very shallow water to the depths of most ports and reservoirs. Tell us the area and we will suggest the method.
