Here is the scenario:

I am performing Union on 2 shapefiles: A & B

A: 300 features B: 8 features.

The result of the union generated is 334. Through the helpful comments I know that it was due to some overlapping features within either shapefile.

So now my question is how to get the union results I want which will simply have 300+8= 308 features.

    Intersect with single input, perhaps you have overlaps in A. – FelixIP Apr 18 '17 at 20:09
  • Sample of your data would help us to help you if you can share some data or create a fake dataset that shows the issue. – user30184 Apr 18 '17 at 20:23
  • If your shapefile doesn't partition space to be mutually exclusive and exhaustively complete (as if it were an FGDB topology), then a self-Union would expose overlaps. – Vince Apr 18 '17 at 20:53
  • You likely have overlaps in your data. Perhaps multipart geometry, though I haven't tested this. – Fezter Apr 18 '17 at 22:16

    Please edit the question to contain new information. It's not fair to those who would answer to need to mine the comments for critical information – Vince Apr 19 '17 at 22:18
