Quarry volume comparison
« on: January 16, 2021, 05:49:49 PM »
Hello, I would like to fly over our quarry by drone and use the 3D data to calculate the volume that was removed between two flights. So once when the quarry wall is still standing and once when a part has been removed. How can I do that?

Thanks in advance!
Sebastian

Hello Sebastian,

Please check, if the article related to the DEM difference calculation is helpful for your needs:
https://agisoft.freshdesk.com/support/solutions/articles/31000156301-transform-dem-functionality-for-dem-difference-calculation

You can process the image sets in the separate chunks or projects and then import both DEMs to the single chunk for the difference calculation. After that draw the polygon in the Ortho view mode over the area where the volume difference should be calculated and open Measure Shapes dialog  - the calculation results over Custom Level = 0 should give you the desired result.
