Asiaq can conduct bathymetric surveys in lakes and coastal areas. From the results of the surveying we deliver maps, contours and digital elevation models. These products are typically used for design and evaluation of construction projects such as harbours, hydroelectric plants and sewage outlets.

Bathymetric surveying is conducted using a combination of an echo sounding devise and a GNSS unit both connected to a computer. This setup can be mounted on smaller boats as well as on a RHIB.
