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 laserscanning provides a reliable and fast method of documenting and monitoring the working status, as well as accurate volume and earthwork computations.

Data recording with a laserscanner ensures high accuracy and reliability and saves on-site inspections, which are difficult or impossible particularly in the case of disused pits located in impassable terrain or in areas at risk of caving in. Attractive visualizations of the elevation data and additional spectral information from the true ortho images permit thematic classifications, among others. Derived information, such as break lines, contour lines and volumes, can be extracted from the elevation data.

 The high-resolution data generated by laserscanning 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 environs
  • Documentation at a specific point in time
  • Monitoring of changes
  • Capturing data of escarpment edges and excavations
  • Determining excavated material and fill
  • Volume computation
  • Subsidence surveying
  • Identification of areas at risk of caving in
  • Simulations in the course 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
