Hi Guys,

I am trying to divide polygons by polygons using the union tool, however, I noticed that there are extra areas that I am getting at the end of the process....here are the steps that I am following


Here are my two original layers: (Paving polygons in green and Plots in purple)

 

 

 

I used the Union  tool

 

 

 

Result:

 

In the attribute table of the output dataset, I deleted the (-1) from the FID_Polygon

 

 

and here you can see the outcome, there are extra polygons (paving) that were not part of the original polygons

 

 

 

as highlighted below 

 

VS. How it looked like before the Union 

 

 

Any suggestions/solutions to avoid having extra polygons when using the union tool?

 

 

Thank you
