The WMS Overlay is a Grid overlay which can display an image result of a Web Map Service query of the project area. The advantage of the WMS Overlay being a Grid Overlay is that it can be used as input for other Overlays, such as the Combo Overlay, to apply filtering based on color values. To make the color filtering easier, the WMS Overlay has optional result types that only store one specific color channel.

When clicking on a specific location in the map of the WMS Overlay, the hover panel gives additional information on the color (channel) value in that specific grid cell, depending on the result type.
Result Types

- Green

Notes
- When set to use the Color result type, the Overlay's colors are not dictated by the Grid Overlay Legend. Instead, the actual color values are used.
