Min max elevation (Water Overlay)

Icon	Attribute	Unit	Range	Description	Default value
	MIN_MAX_ELEVATION	Nominal value	0 to 2	Whether to use highest and lowest elevations found for a grid cell for land and water respectively when interpreting the elevation model.	1

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.
