Acquisition and processing of hydrographic data are performed by HYPACK® software. This software is used to visualize the data collected, to compare it with older documents (pictures, maps scanned, etc.), to compute the volumes to be dredged, and to export the results in various formats (paper, digital).

NEW - Géopolynésie has now a new partner and can therefore meet topography markets by airborne and/or terrestrial Lidar. Difficult and/or heavily wooded areas can be raised with an accuracy better than 5 cm.

Géopolynésie can rent all the necessary devices to carry out multibeam echosounder surveys and sedimentological surveys.
