Fairly new with arc. Using 10.2.2. Basically what I am trying to do is create a heat map using z scores ranging from 23 to 1322. I used IDW and got a sufficient result but it would look nicer if the results were more rounded or circular and did not just a square around the outer most points. Are there any other tools that give better looking results or are there any tricks to make this work that I am not aware of?
