What is the difference between bathymetric and hydrographic surveys?
Bathymetry measures water depth and bed shape; a hydrographic survey is broader and also covers navigation features, tides, currents, shoreline and seabed classification.
Do you survey inland waterways?
Yes. We survey rivers, canals and inland waterways as well as coastal and port areas.
What deliverables do you provide?
Processed depth data, charts, sections, seabed feature maps and a survey report.
Do you provide Hydrographic Survey in Kolkata?
