I'm trying to create a heat map in ArcMap 10.4.1. I've already selected a base map, created a shapefile out of my data points, and overlaid that shape onto the map. Next I go tools -> point density. I set Input Point Features to my shapefile. I click on environments, then Raster Analysis, and then I set mask to my shapefile. Finally I go to Processing Extent and set the boundaries I want using another layer.

After all of this, I get the entire area filled in with one solid uniform color. The densities of the points are not reflected at all. Also, when I look at my table of contents, I see that the ranges for every single color are the same.

Can anyone tell me what I might be doing wrong?

  • what happens when you dont mask it to the shapefile? – ed.hank Jul 29 '16 at 14:52
  • Actually now every time I do this, whether I mask it to the shapefile or not, the ranges for all the shades are 0-0 and nothing appears on my map – Judy Garland Jul 29 '16 at 15:10
  • have you tried maybe kernel density? – ed.hank Jul 29 '16 at 15:21
  • ok really not sure what happened, but I started completely over with a blank map, recreated the shape file and now it's working. Thanks for your suggestions, I appreciate it! – Judy Garland Jul 29 '16 at 16:02
