With an area selected using the Polygon tool, you have the choice of three distinct measurement types for measuring the volume within the area contained by the polygon.
Types of volume measurements
There are three types of volume measurement tools:
- Smart Volume: Interpolates a base from the surrounding terrain using the selected points. See how to use Smart Volume.
- Volume Compare: Calculates from a previous dataset or imported design surface. See how to use Volume Compare.
- Reference Level Volume: Measures from a horizontal plane based on a defined reference level. See how to use Reference Level Volume.
- Custom Base Volume: Customise the base from which a volume is measured by adjusting the elevation of the polygon's vertex points. See how to use Custom Base Volume.
When to use which measurement type?
- Smart Volume: Useful for estimating volumes on a flat or largely even base level such as inventory in stockyards.
- Volume Compare: Useful for measuring progress and change or producing accurate measurements with flight pre-work flight or design surface as a base level.
- Reference Level Volume: Useful for measuring sections from a known base or toe such as large excavations or mine benches.
- Custom base volume: Useful for measuring stockpiles with irregular bases such as piles located on top of batters, benches or bins.
