Recommended Posts

i quote for you

Volume Measurements tool will be soon available on the WebODM. Basically, Volume estimation could be seen as a change in both surface & elevation. So, if we come up with the surface of our area of interest and the variation of elevation we can then estimate our Volume ... So here are some basics steps that could be implemented as well;

  1. Reprojecting The user's input contour to the DSM....
  2. Clip the corresponding area over the DSM...
  3. Estimate an average height of the user contour
  4. Compute Normalised DSM over the clipped area (nDSM=Cellsheight - Avgheight(contour))
  5. Volume = AOIsurface * nDSM
