HOW TO MANAGE A QUARRY

1.1 THE DATA NEEDED FOR THE STUDIES:
Nature Where ? How ?
Orthophotos Open Data (IGN, others,…) DataBase repertory
Orthophotos Drone (specific production) DataBase repertory
Cadastre Open data DataBase repertory
Network managers Specific requests DataBase repertory

  • Each data contained in DataBase can be shared and downloaded.
    – Quarry operators thus have all the data needed to conduct their studies, which can be used independently of GeoCassini in their
    own business applications
    To note : GeoCassini’s “GeoStore” functionality allows any external application to be directly connected to DataBase.
  • You can upload and share additional data yourself.
  • Dealer networks can be imported from CAD or GIS software in .dxf, .dwg, .shp formats. json. kml, etc.
    To note : generally the network plans are in 2D. GeoCassini makes it possible to integrate these plans by automatically assigning them
    an altitude from lidar data (reference altitude or depth).
Create a point cloud coverage of the quarry
WHY?
A 3D colorized point cloud survey makes it possible to fully describe the quarry with centimeter precision.

This point cloud is then used in GeoCassini to:
• produced a topographic plan
• navigate dynamically and in an immersive way in the career facilitating the identification of particular points and facilitates “field” diagnoses
• integrate the different planning hypotheses, measure their impacts
• improve exchanges between employees
• monitor the execution of the work
• perform various volume calculations
• Generate listings

Example of point cloud survey made with a drone
Synchronization of the Orthophoto view on the left and the point cloud on the right
HOW?
Through a photo drone using photogrammetric processing or with a Lidar drone.
Example of a working face drawing made from lidar coverage
Example of navigation and measurement in the point cloud
Example of integration of new conveyor trucks
Example of importing an IFC object into the point cloud, for track calibration control
Example of quarry development monitoring in purple the 2018 point cloud and in red that of 2019
Example of volume calculation on a heap
Example of calculation compared to an existing DTM of the end of quarry operation project
Visualization of the result of the volume which remains to be extracted on a zone of the quarry
Visualization of the various calculations on the whole project
USE THE DOCUMENT PART OF A PROJECT TO ASSOCIATE ALL TYPES OF DOCUMENTS
Example of using the EDM part in GeoCassini
