I have a point set that I select in the IDW input menu, it has over 4000 points. But when I attempt to run the interpolation it gives me the error message that i do not have enough. Help says i need 2 points to do this. Obviously i have more.
I was able to create a thiessen polygon set with the points without error. Also this error comes up when i try Spline and Kriging. I am stuck asking for some assistance please.
