Description

The Volume Measurement algorithm automatically calculates cut-fill volume for areas of interest delineated by the user. It takes in a point cloud (.las) and area(s) of interest (AOI(s)) as inputs and generates a GIS vector file (shapefile) and KML file representing the user-defined piles along with their respective cut, fill and total volume.

The method accounts for the base terrain slope. Unlike approaches that assume a flat and horizontal base, this volume measurement interpolates the base height from the elevation under the vertices of the area of interest delineated by the user. The cut and fill values are calculated based on this interpolated base terrain height instead of simply calculating it from the lowest height (flat/horizontal).

This approach provides good results when the AOI is delineated directly on the base terrain. It is not recommended to attempt isolating the volumes from closely adjacent piles or piles adjacent to a cliff.

Inputs Outputs
  1. Orthorectified Image (GeoTIFF)
  2. Select from list of available survey orthomosaics that include DSM output
  3. Indicate the boundaries for your stockpiles and/or pits. It is suggested to keep the AOIs close to the boundary of the pile.
  1. GIS vector file (shapefile) representing AOI polygons and containing volume calculations for each AOI in cubic meters and yards.
  2. Google Earth friendly file representing AOI polygons and containing volume calculations for each AOI in cubic meters and yards.
  3. PDF report depicting 2D map of results
