I have a single layer with shapes (raster cells) that represent all countries on earth (the figure below shows france). Each shape has specific attributes.
Is it possible to merge the shapes by their attributes? E.g. if attributes x,y and z in shape 1 are the same as attributes x,y and z in shape 2 ... then create a shape that covers the area of shape 1 and shape 2 and contains the attributes x,y,z?
Example: If I have the attribute table displayed below, I would like to merge the shapes with the ID 2 and 7 to one shape.
I have tens of thousands of shapes with hundreds if not thousands of different attributes. I'm afraid doing anything manually is not an option.
