I have several different shapefiles that I want to combine into one based on the minimum value of each attribute. I found this solution. However, I also want to know which shapefile each minimum value came from.
For example, I have 5 shapefiles with values in each one of 10 attributes. For each attribute, I found the minimum value from one of the 5 shapefiles using the method in the solution above. But I also want to know which of the 5 shapefiles the minimum value came from for each attribute. Is this possible?
