The Smart Volume tool triangulates a grid below the surface of a polygon feature drawn on your site. It uses this grid to estimate the base level of the feature, and automatically calculates a volume above this base level.

Smart Volumes are useful for estimating volumes on a flat or largely even base level such as:

  • Measuring stockpiled material in stockyards or ROM pads.
  • Measuring the volume of excavations, pits and trenches.
  • Measuring the volume of material stockpiled on sloped ground.

How to use Smart Volume: 

  • Draw a Polygon around the area of interest, and open the volume measurement tool in the annotation panel. 
  • Select "Smart Volume" from the dropdown list in the volume measurement tool. 
  • The Net volume represents the amount of material required to reach the Smart Volume's interpolated base level.  
  • In the example below, the Cut volume of 386m³ represents the volume of material above the Smart Volume level, while the 1.7m³ of Fill represents voids. In order to reach the Smart Volume's base level, the Net volume of 386m³ would need to be removed, which is why the Net volume is a negative number of -386m³.

The difference between Smart Volume and Reference Level Volume

  • Smart Volumes allow for the measurement of stockpiles on ground that has a slope. (e.g. gravel dumped on a ramp or other sloping surface).
  • A Smart Volume takes into account the sloped surface by using polygon triangulation to interpolate the base of the stockpile from the elevation of the surrounding terrain.
  • A Reference Level Volume uses a horizontal plane projected from a a Reference Level. Measuring material stockpiled on a slope using this tool would include a slice of the terrain beneath the stockpile as can be seen in the diagram below.
