Water stress result type (Water Overlay)
|The amount of water on the surface, similar to SURFACE_MAX_VALUE. Ignores water on water terrains unless it exceeds ALLOWED_WATER_INCREASE_M.
¹ the units between () are as displayed in the 3D client. If exported to GeoTiff the SI-convention is used: meters (m) and seconds (s).
Any water on the surface is considered water stress. Open water is usually designed to function as a buffer for water, meaning an increase in the amount of water is not necessarily considered stress, unless the water level increases too much. "Too much" is defined by the ALLOWED_WATER_INCREASE_M attribute. As long as that amount of water is not exceeded, water stress in that location is considered 0.
