Rain area (Water Overlay)

A Rain area is a feature which can override the Weather's rain with a new rainfall array. This allows users to simulate rain clouds moving over the project area.

Icon	Key	Unit	Range	Description	Default value
	LIMIT_RAIN	nominal value		Whether rainfall can be overridden by rainfall defined in rain areas across the project area.	0 (Entire map)

Notes

• A maximum of 10.000 values (5.000 pairs) can be defined per rain area.
• Up to 100 rain areas per water overlay are supported.
• For locations without an overlapping rain area, the Weather's rain m is applied.
• The configured weather dictates the simulated time and optional starting date.
