Coastal erosion and sand drift monitoring
Aim of the costal monitoring is to clear out geological processes, drifts ad costal change tendency in space and time. Monitoring results with control of significance of costal erosion processes in the zones at risk and determination of new zones at risk. Control is also performed for local changes in costal zone after impact of harbours and other hydro technical buildings.
Monitoring is carried out by distance study method - laser scanning, and data obtained are used to produce 3D models. Data on lost or gained sand volume are obtained. Aerial photos, taken at different time periods, are used to compare and set out the distance of costal recession.
Monitoring results are used for territory and harbour development planning. Metrum owns an aircraft equipped with laser scanner and high resolution camera, capable to obtain data to be used for 3D terrain models.
