Opencast Pits and Deposits

For opencast mining (opencast pits, quarries, sand and gravel pits), as well as for landfill sites and dumps, 3D data acquisition by means of aerial laser scanning provides a quick and reliable method of documenting and monitoring the working status, as well as accurate volume and earthwork computations.

Data recording with an airborne laser scanner ensures high accuracy and reliability and eliminates the need for most on-site inspections, which can be difficult or impossible when disused pits are located in impassable terrain or in dangerous areas. Easy-to-read visualizations of elevation data and additional spectral information from the true ortho images permit thematic classifications and analysis of derived information, such as break lines, contour lines and volumes.

The high-resolution data generated by aerial laser scanning of redevelopment areas, opencast pits and landfill sites are the foundation for the following fields of application:

  • Wide-area acquisition—also of disused areas and the surrounding environment
  • Documentation at a specific point in time
  • Monitoring of changes
  • Capturing data of escarpment edges and excavations
  • Determining excavated material and fill
  • Volume computations
  • Subsidence surveying
  • Identification of areas at risk of caving in
  • Simulations of rising groundwater
  • Planning recultivation measures
  • Authorization and project approval procedure
  • Mine surveying production and safety control
  • Superimposition of additional georeferenced information in a GIS
