we'll provide the best technical solutions for your hydrographic or topographic survey, within your project constraints

DML operates a range of technical solutions for hydrographic and topograhic surveys including multibeam echo sounders (MBES), single beam echo sounders (SBES), Side Scan Sonars, mobile laser scanners (MLS) and tide gauges.

Side Scan Sonar

Side Scan Sonar

Often used where cross section profiles are required or where shallow depths preclude the use of MBES

Used to collect complete surface profiles for in-shore shallow water and deep water surveys in excess of up to 450m deep

Often used for coastal and river surveys and target detection, where a sideway view is required and a downward looking sensor is not appropriate

Static & mobile laser scanning

RTK, DGPS, WADGNSS used to provide referencing and highly accurate positioning

Used to remove heave and motion from data to ensure accurate depths are recorded

Used to gather and provide seamless coastal and near shore surfaces by combining land imaging with underwater imaging
