I am trying to make a map like the one that appears below using ArcMap 10.5.1. I know how to make the colored circles, but what I do not know is how to plot the background. This background shows predicted values for a finely spaced grid of longitude-latitude coordinates from a regression using latitude and longitude, and another explanatory variable.
However, I don't know how to do it. I tried using the GWR, but only managed to get small colored circles with the results, not to plot it across the entire surface.
Any help would be greatly appreciated.
