In the first quarter of the year we have undertaken several Topographic Surveys in different rivers in Guipúzcoa, for the Obstacle Permeabilization Projects that the Provincial Council of Guipuzcoa is carrying out.

In total, there have been 5 dams and river sections between 100 and 400 meters in length in each survey.

We have used different means to capture information: GPS, Total Station and Laser Scanner.
