Cut and fill volume calculation
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

Hi Adam,
You can use Analysis > Measure Volume Between Surfaces
Assuming:- DTM2 is the layer to subtract from
- DTM1 is the layer to subtract
Measurements:Total Volume Between Surfaces: 9947.185 cubic metersCut Volume: 8038.4232 cubic metersCut 2D Surface Area: 4931.6 sq mCut 3D Surface Area: -Fill Volume: 1908.7617 cubic metersFill 2D Surface Area: 13809 sq mFill 3D Surface Area: -LAYER_COMPARE: DTM2.tifLAYER_BASE: DTM1.tifREPORT_TIME: 01/06/2017 12:23:07AVG_Z_DELTA: 0.327 mMAX_Z_DELTA: 5.345 mMIN_Z_DELTA: -1.599 m
