I have 200 shapefiles (polygons) which I need to union them all into one layer. I need union it in order the overlapping could shows the intensity area. however, i am having problem to union all of the shapefiles. Why this is happening? i only manage to union like 65 files of the shapefiles... the ERROR 000210: Cannot create output... Failed to execute (Union).
keeps on popping out... it is stressing me out. i could not do the next step (which is to know the intensity of the overlapping area) if i could not manage to union all of these shapefiles..
