Loading the DEM at a higher resolution allows the skipping of an interpolation step, so the interpreted [[Elevation model (Water Overlay)|elevation model]] becomes more accurate. This improves flow throughput in very small channels and reduces grid flow artifacts, at the cost of additional calculation time.

Loading the DEM at a higher resolution allows the skipping of an interpolation step, so the interpreted elevation model becomes more accurate. This improves flow throughput in very small channels and reduces grid flow artifacts, at the cost of additional calculation time.

Notes

  • This attribute only works for a grid cell size <= 0.5m.
  • This attribute is by default set to 0 which means increased DEM resolution is not used.
  • In the advanced settings step of the Water Overlay Wizard, this attribute can also be (de)activated.
