The issue
During the remediation of an industrial site, Envicom Associati carried out an aerial photogrammetric survey by drone in order to obtain a detailed topographical survey of the entire construction site area.
The work developed in the following phases:
- Positioning of markers on the ground;
- Topographic survey with differential GPS;
- Images acquisition with drone;
- Reconstruction of the 3D model;
- Point cloud processing;
- Creation of DEM and geo-referenced Orthophoto.
With the survey it was therefore possible to map in detail the excavations carried out for the purpose of remediation and estimate the volumes of excavated material.
