Virtual Surveyor helps you to calculate stockpile volume above a base surface. That surface may have been imported into the project or created within Virtual Surveyor. Virtual Surveyor includes tools that help surveyors to perform those calculations in a simple and accurate way.
This article describes a step by step guide to help you calculate your stockpile.
- Clean the stockpile terrain.
- Select the surface.
- Select the material.
- Calculate the stockpile.
- Set the visualization options.
- Export results and report.
Preparation : stockpile terrain cleaning
Before launching a stockpile calculation, it's important to remove objects that hang over the pile. Indeed you don't want to include them into the material volume. Conveyors and machines like wheel loaders are often over stockpile. In general, the first step is to remove those objects by using Replace terrain tool.
You can have a look to that article that describes how to remove conveyor even in a complex environment.
Stockpile base surface
Select the material that makes up the stockpile from the Material dropdown menu. By default, only Undefined is available. You can create and manage materials through the Material Editor.
Notes! It's possible to change the material after the stockpile creation via the SELECTION - TOOLS for Stockpile.
Launch the stockpile calculation by clicking on the Stockpile button in the Volumes group of the SELECTION - TOOLS tab.
The volume calculation is done between the current terrain and the selected reference type.
Results visualization and export
Stockpiles volume values are available in the Volume box along with other inventory info. If you want to display that volume value within the viewport activate Volume checkbox in the Annotation settings that you'll find in the SELECTION - TOOLS for Stockpile.
You can create a Stockpile PDF report by clicking on PDF Export button in the EXPORT tab.
You can also export stockpiles values as a spreadsheet (.csv) or GIS file (.shp). Go to the EXPORT tab. Set the right export format in the box and click on Export Stockpile button.
Tips and Tricks
- You can also launch multiple stockpile calculations in one click by selecting multiple surfaces before clicking on Stockpile button.
- It's possible to import DXF file to define stockpiles base surface. For example, if you have to regularly monitor stockpiles that have the same base, you can import DXF bases file.
- To get a better volume annotations visualization within the viewport use the top-down 2D mode.
- If stockpiles overlap, use Interpolate Z feature to draw the boundary.
