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.
