Hello,

I have a task where I need to calculate the volumetric difference between two DTM's. What would be the correct method to find this difference? I have attached the file with these DTM's here.

https://www.dropbox.com/sh/7ic8lm0a9lu8wo4/AAAR8_XK5P6L3rdniegHo4WPa?dl=0

The coordinate system is GDA 94 / MGA 56. Any assistance you can provide is greatly appreciated.

Thanks

Adam
