Hydrographic Surveys

Gallery Gallery Gallery

Our experience in bathymetric surveys, habitat mapping and cartography is extensive, having completed surveys in many areas in Australia. Utilising a boat mounted DGPS and dual frequency sounder linked to a data logging program and a laptop we produce detailed habitat and bathymetric maps to Australian hydrographic survey requirements. Habitat types are ground-truthed by a digital single CCD drop camera which records to an Archos PMA440 unit with GPS overlay function for later review.
