In situations where the calculation grid size is larger than the elevation model's accuracy, the values for the elevation model are averaged per grid cell to compute a matching elevation model. This setting computes multiple averages to be computed, and the highest value to be used if the grid cell is land, and the lowest value to be used if the grid cell is water. This allows smaller waterways to be preserved better when the interpreted elevation model for the [[Water Overlay]]'s calculations is less accurate.
If the calculation grid size exceeds the elevation model's accuracy, values are averaged per grid cell. This setting computes multiple averages, using the highest value if the grid cell is land and the lowest value if the grid cell is water. This better preserves small waterways when the [[Water Overlay]]'s interpreted elevation model uses larger grid cells.

If the calculation grid size exceeds the elevation model's accuracy, values are averaged per grid cell. This setting computes multiple averages, using the highest value if the grid cell is land and the lowest value if the grid cell is water. This better preserves small waterways when the Water Overlay's interpreted elevation model uses larger grid cells.

0. Never : This option is inactive.
1. Cell ≥ 2m: This option is active for cells larger than 2 meters.
2. Always: This option is always active.
