Virtual Surveyor includes Stockpile tool that allows the user to easily measure quantities from his drone surveys. Stockpile button appears in the TOOLS tab and only works on selected boundary or surface items. 


The Stockpile tool behavior is slightly different if you select a surface or a boundary.


The final outputs are stockpile items along with quantities and values display in the volume box. You can then export those stockpiles as a PDF report or a CAD/GIS file.


Quick guide for surface 

  1. Select a surface.
  2. Go to TOOLS tab, the Stockpile button becomes enabled in the Volumes group.
  3. Select the Material of the stockpile.
  4. Calculate the volume by clicking on the Stockpile button.
  5. A Stockpile item is created in the viewport and the volume quantities are available in the volume box.






Quick guide for boundary 

  1. Select a boundary.
  2. Go to TOOLS tab, the Stockpile button becomes enabled in the Volumes group.
  3. Select the Reference Type and set the expected value/terrain if needed.
  4. Select the Material of the stockpile.
  5. Calculate the volume by clicking on the Stockpile button.
  6. A Stockpile item is created in the viewport and the volume quantities are available in the volume box.



Reference type

When using the Stockpile tool with a boundary, you have to select the reference type. Virtual Surveyor allows you to choose from 4 different refence surface types.

  • 3D Surface: Reference surface extrapolated from the boundary vertices.
  • Flat: Flat surface set at a user defined elevation. The elevation value needs to be set by the user in the Elevation box
  • Flat Minimum: Flat surface set at the elevation of the lower vertex of the boundary. 
  • Terrain State: Other terrain available in the project. The reference terrain needs to be set by the user in the Reference State box. This option is only available when the project contains at least two terrain states

Usage

  • Quantity survey - stockpile volume calculation. As describe in the article, the tool is useful to assess stockpile quantities even when these pile are dumped within walls.

  • Mining survey - blasting estimation. If a design surface is available, use it to asses blasting volumes.


Tips and Tricks

  • When using a surface to calculate a stockpile, the volume calculation will be done between the current terrain and the selected surface. 
    • Current terrain means the elevation terrain and the active terrain modifiers (for example after removing a conveyor) that are applied on top of the terrain.
    • All available data points will be used in the calculation.
  • The Stockpile output is a Stockpile item. Yo can control its visualization settings through the TOOLS tab
  • You can also select multiple surfaces or boundaries and volumes will be calculated for each item separately.
