I have not been giving any data, but I have been told that I could be expected to recreate maps In ArcGIS 10. Below is an sample portion of what I may have to recreate. I have no idea how to get symbology like this for point data. Graduated symbology would only work across the array of points. How do I get one point to have the color variations like seen below? The points are representing observation density. I know how to obtain and symbolize basic data. I don't need information on how to get the hydrology layers or symbolize the eagle point. I need to know how to do the red circles.
Heat maps are not what I need since the "blanket" the entire area.
