Mining

We perform topographical surveys activities and volume calculations of quarries and material storage areas using traditional instruments, such total stations and GPS, or using aerial drones (UAV) for large areas and more detail. Main activities:

• Delimitation of surveying areas creating an accurate geodetic network by setting of monuments or markers into the ground and measure by professional GPS in static mode and posprocessing calculations.


• Perform detailed survey with traditional instruments (total stations & GPS)of the orography, hydrography, roads, buildings, vegetations of the interested areas.The results is an accurate elevations plan with many xyz point to create detail terrain mesh or contour lines model.


• Aerial survey and photogrammetric technology by drones (UAV) to obtains:
  -- Georeferenced digital color orthophotos with 5cm accuracy or better with the ground control points
  -- Generation of precision DTM and DSM models to provide volume analysis.


• Creating 3D models and colored Point Cloud.


• Volume analysis


• Generation and calculation of typical sections.
