I am generating a map where I have sentiment value for geo-tagged data. I want to show a heat map based on the sentiment of location. I am using kernel density to generate this map.
I am having trouble in understanding how does the 'kernel density' function calculates output density values when I am entering the sentiment as the parameter?
What role does the radius and area parameter play in the result?
Is kernel density the right option to generate such a map?
I am using ArcMap 10.3.
