DREDGEPACK® requires a filled MTX and cannot use the AutoMatrix option.

  • TIN MODEL can fill a blank matrix.
  • XYZ TO MTX can fill a blank matrix.

For each matrix cell, DREDGEPACK® tracks:

  • The ‘As Surveyed’ depth. 
    • Doesn’t change z-value.
    • Populated in TIN MODEL or Mapper

  • The ‘As Dredged’ depth
    •  Initially set to ‘As Dredged’ z-value.
    • Updated with the depth at which the cutting tool has passed through the cell.
