How does ODMWeb calculate the volume

WebODM

Hi all !

I just arrive here in this forum
I use a Macvic 2 Pro

I want to use it to compare volume before and after earthwork.
I mean : I work in a land, I do my fly and i save my pictures. After there are some earthwork that change de topography of the land. I do the same plan of fly again.
I would like to compare the difference between before and after the earthwork.

I’ve seen on ODMWeb that I can mesure the volume.
I’d would like to know how the volume is calculated. Is it from the lowest point that ODM calcul the volume ?
Is it possible to put compare the two flys on the same project : to calculate the difference between before and after the earthwork ?

Thanks so much for your help
Pierre

Hi @pierotofy,

This link does not exist anymore. Can you provide the present link? And provide more details on how it is can be used separately only to measure volume?

Thanks,
