Hi everyone!

I’m trying to calculate the volume of different segments in the same scene. When I use the “segment statistics” I obtain a table with 2 differents values of volume of the same segment. (screenshot below) Does anyone which are the differences or what does each volume mean?

Thank you so much,

Núria
