Hi Eric,
Thanks for getting back to me. You are correct in that the pattern is not as distinct as my last post. The data in my last post was evenly distributed and there were a lot more points closer together, so I think the pattern was more dramatic. Here my point dataset is a bit more sparse and not evenly distributed, and at that scale I think it was a bit hard to see. I have attached a new pdf that is zoomed in more and shows the dots a bit better. There are two screen shots, and one includes the point dataset used for the interpolation. As you can see, it looks as though the dots on the raster are forming at where the points are.
Also, while I have you here and sense you're a GA product engineer, I was wondering if you knew of any materials that go into depth on GA, in particular determining which method/parameter/model/transformation etc. to use. I have read the GA tutorial provided by ESRI, but it doesn't go into detail on each of the parameter options for the different interpolation methods. I usually find myself using what others have used in similar situations, or just guessing and trying different options until I find something that works, but when I'm writing up a report/paper, it's nice to have reasons why I chose certain parameters. If there are any materials, books, etc. that you think would be useful, I would greatly appreciate any recommendations.
Thanks Eric!
