AERIAL PHOTOGRAMMETRY, EXCAVATION SITE AND VOLUME CALCULATION

I firmly believe that drone aerial photogrammetry is, at the moment, the most effective technique, considering how much it costs related to the benefits it provides, for the survey of aggregates quarries, excavation sites and storage areas.

The absence of vegetation allows you to take truly representative photographs of the ground.
You can see it clearly from the pictures.
There’s no plants that hide the soil.
So you won’t need to hard process the 3D point cloud, cleaning it and classifying the points.
‘Cause it could be hard otherwise.

Excavation site and stock piles

Big areas are well covered by aerial photos taken quickly by a flying drone.

The 3D model out from the photogrammetric process allows an accurate, realistic and fast calculation of stock piles volumes.

The most time demanding part of field activities is positioning and topographically measuring the coordinates of artificial targets on the ground, GCP (Ground Control Poins).
Theese data will support the structure from motion process inside the photogrammetric software.

Unfortunately, these areas are constantly evolving and changing, so it’s not easy to find fixed references on the ground to be used, again and again, for any repeated surveying activities over time.

I took this photo during an aerial photogrammetric survey in Holcim storage area in Gorla Minore (VA) – Italy.
