I know this sounds quite difficult, but maybe it isn't for you or at least it shouldn't if I explain it correctly.
(I'm using QGIS 2.14) I'd like to know to calculate total area overlapping a specific raster DEM color (user-specified altitude interval) whose boundaries are confined by another vector.
So basically there's a raster DEM as background map, I assigned a specific color to an altitude interval. I applied a vector I created to show where boundaries of a certain area area. Now within this area, I applied another raster which partly overlaps the altitude interval I applied in the background DEM.
I'd like to know what is the area, within the vector boundaries, that overlaps my altitude interval in the DEM map.
EDIT: I tried running raster calculator on intersections then zonal statistics checking "count" and "sum" but I get a huge table of 8000+ rows and two columns, however each cell usually have a value around 0.4 or 1.x, so I don't know how to interpret this or if I should somehow sum all those cells together to get the number of pixels falling in my area of interest (overlapping altitude range, shaded and within vector bounday).
