Hey @Aditi
DoD stands for Difference of Digital Elevation model .

  1. DoD - this method is useful when you want to calculate complete stockpile or excavation volume
  2. Min - this method is good when you want to calculate partial volume of stockpile
  3. Max - this method is good when you want to calculate partial volume of excavation
