Base Calculation​

-

The points that define the base are triangulated. For this reason it's important to make sure that the base is visible and that the surface is relatively flat.

+
A dialog box will appear. Calculation of the volume can take a few seconds to a few minutes, depending on the size of the area and the resolution of the DSM. After processing is complete, the results will be displayed. The base surface method can be changed.
+

Base Surface​

+

The definition of the base surface can be calculated using one of several methods, listed below:

+
MethodDescriptionBest WhenDefault
TriangulatePoints are triangulated and a surface is linearly interpolated from the results of the triangulationBounds of the stockpile are visible and surface is mostly flat✔️
PlaneFits a plane that is minimally distant from all pointsBounds of the stockpile are visible and surface is hard (e.g. cement), sloped or flat
AverageA plane with height set to the average height of all pointsThe surface is relatively flat, but with some variation (averaging helps smooth out variation)
HighestA plane with height set to the maximum height of all pointsCalculating fill volumes of containers or enclosures (e.g. swimming pools)
LowestA plane with height set to the minimum height of all pointsBounds of the stockpile are not visible (e.g. hidden by a wall)

Exporting Results​

Press the Export to GeoJSON button to export the volume calculation in GeoJSON format.

Accuracy​

With proper data capture, GCPs and when GSD is ~1 cm / pixel, the expected accuracy should be within 1-2%.

Field Planning​

The use of Ground Control Points is recommended as well as following all guidelines for creating successful maps with a target GSD of 1 cm / pixel.

-

For the flight pattern, stockpile measurement tasks typically do not require a crosshatch pattern or an angled gimbal, due to the natural inclines of stockpile materials. Only in certain cases, such as when erosion creates steep angles on the stockpile, would a crosshatch flight pattern and angled gimbal improve results.
