I've two layers, both with the same fields: A, V, where A is the shape's area and V a value given by me. I want a new layer with shape created by the intersection of the other layers' shapes and a value given by the calculation: (A1*V1+A2*V2)/(A1+A2). Is there a command to make it automatically? Obviously in reality I have many layers with many shapes, otherwise I made it manually.
I used intersection to subdivide all shapes from all layers; in this way for every shapes I have 2 weights (V values). Now I can use vector-field calculator and calculate:($area*("x"+"y"))/(sum(x+y), where x and y are the 2 weights. I hoped there was a command that make it automatically… It's possible at least calculate summation of x and y values in vector-field calculator?
