I have five vector files wherein I want to determine the spatial agreements among them using intersect. Here is my illustration. (Actually these are forest shapefiles from five different forest maps.)
A = vector_file_1.shp B = vector_file_2.shp C = vector_file_3.shp D = vector_file_4.shp E = vector_file_5.shp
So that I will have a set of spatial agreement from 2/5, 3/5, 4/5 to 5/5. For example:
1) 2/5 = A∩B, A∩C, A∩D, A∩E, B∩C, B∩D, B∩E, C∩D, C∩E 2) 3/5 = A∩B∩C, A∩B∩D, A∩B∩E, A∩C∩D, A∩D∩E, A∩C∩E, B∩C∩E, B∩C∩D, B∩D∩E, C∩D∩E 3) 4/5 = A∩B∩C∩D, A∩B∩C∩E, B∩C∩D∩E, A∩C∩D∩E 4) 5/5 = A∩B∩C∩D∩E
My question is what geoprocessing technique will I use to generate a single shapefile from each agreement above (except item # 4), supposing I've done the intersection combinations for agreement items 1-3? Will I use intersection again, union or other technique?
(My professor told me to just add a field and put a number code on that field, for each shapefile, unfortunately I forgot the next process he mentioned.)
