I have 1,000 point locations that represent hospitals, and I want them to be symbolized as different colored points. Since a map reader isn't going to tell the difference between 30 shades of red or blue, I can't have the same colors for neighboring points. Neighboring points, which represent different hospitals would imply the same organization or hospital institution (which isn't the case). What I've tried is using the Near tool in ArcGIS Pro to find the closest point for each point and what the distance is to it. Where I'm stalled is applying a staggered symbology, so that points within, say, 20-30 miles aren't given the same color.
I've also explored trying this with Python where I iterate through each feature point, use a buffer to define the area that I don't want to repeat the symbology, then apply a symbology, and move on to the next point. I'm not sure this is the correct path.
Does anyone have any other ideas for applying symbology based on proximity of features to each other?
