please have a look at marpet’s answer on a similar topic. He suggests the mask manager to evaluate the amount/size of pixels which have a defined value:

@qglaude that’s one option. The other is to create a mask. As mask expression it should be possible to simply use the band name. If this doesn’t work an expression like bandName == value should do it. [image] Then you can compute the Mask Area (Raster / Masks / Mask Area). This will provide you a window with the following information: [image] Or you go to Analysis / Statistics and compute the stats with the mask enabled. So there are multiple ways.
