Hydrographic Surveys in London, Sussex and Surrey

Cadmap Limited offer Hydrographic surveys for detailing rivers, lakes, reservoirs, harbours, marinas and ponds.

We operate specialised equipment and software to capture underwater data, a remote controlled catamaran for sturdiness while in the water, a SonarMite Hydrographic Echo Sounder that is synced with a Leica GPS device fixed to the boat to give real-time data collation and can record survey points every second.  

Using an RC Boat also eradicates a person having to get into the water or working on water.
