Digital Photogrammetry with Drones

Photogrammetry is a solution that integrates several technologies, in order to obtain three-dimensional terrain models (3D) as well as an error-free orthophoto (2D) for planimetric analysis, all of this accurately georeferenced, both in a global and local system.


  1. The execution time of a project in the field is considerably reduced, approximately 25%.
  2. Extensive surveys.
  3. Terrain representativeness.
  4. Remote work, which allows operators to be away from risky areas (falls, machinery traffic, etc.).
  5. Productivity and effectiveness.

Necessary information: photographs obtained by UAV and GNSS observation files + post-processing software.


Photogrammetric products

Point cloud, three-dimensional georeferenced model of millions of points, which allows to work in 2.5D and 3D to be able to apply different designs on it or to analyze with precision the terrain.

Rectified orthophoto

Error-free, scaled and accurately georeferenced image of the terrain, which allows to work on planimetry as well as to generate calculations on it.

Topographic and mining products SURFACES

Generation of highly representative surfaces due to the density of three-dimensional modeling points, and are exportable to other formats, dxf, dwg, ttm, Landxml, to be used in other softwares.

Generation of contour lines in different intervals.

Exportable to other software and compatible with GConciliation.


Obtaining the position of georeferenced pits in an accurate and automated way, the design/actual difference calculations allow correcting possible errors, interferences or lack of technical specifications. All this without the need to enter the work zone.

With all the information available, it is possible to execute the drilling and blasting work, maintaining continuous control over each of the steps carried out, through the use of the Drone.

Material volume control

Whether for control of sponging, dumps, material displacement, stock pile or earth movements, generating short, medium and long term analysis, with their respective reports.

Condition Factor

The photogrammetric products either orthophoto or the three-dimensional model are used as information to determine the values of perception of the bank stability, given its high level of detail allows a better evaluation of the top of the bank for subsequent analysis in GConciliation and other software, all this without interrupting the operation, maintaining the safety of workers. This information is weighted according to its relevance in the quality of the slope and the risk of instability or rock fall.

Photography and recording

Drones allow acquiring high resolution images and filming videos from angles that are not possible from the ground, controlling the safety of the operator who is located in a safe area. In this way it is possible to analyze the behavior of the blast and the flow of material, as well as any possible incidents that may have occurred during detonation. Necessary to document blasting, detection of injectable elements, identification of instruments in inaccessible places, inspection of structural failures and their analysis.


Base topography with a high level of detail for engineering designs, necessary for conceptual engineering, analysis and previous calculations in an accurate way. Different designs can be generated, ramps, mine road, dump, and their respective cut and fill reports, profiles, longitudinal profile, etc.


The rectified orthophoto allows the analysis of fragmented material of the different blasting zones, without the need to use physical scales on the ground since it is georeferenced and scaled. Thanks to this, this procedure can be carried out without exposing the work team to the risk area.


Generate by photogrammetry, a 3D model of the bench and thus obtain contour lines (Base File), which allow us to have the input used by the reconciliation software.
