Using the point density tool causes a blank area on the map.

[JamesMartin6]

Hi,

When I use the point density tool in Arc, it creates this large blank area under the points used. No matter what extent I zoom in or out to it maintains this same problem.

From looking at the image, it looks like it is acting correctly by making darker areas under the points (thus indicating higher density) and lighter areas in between the points (low density). Can you show a zoomed in screen shot where there are blank areas?

Also, it would help to move this thread to a place like GIS​ or Managing Data​ since the GeoNet Help is for help with the GeoNet.

Thanks, I'm not terribly familiar with this.

It is behaving as expected... the help file even shows an image Point Density—Help | ArcGIS for Desktop and there is a description of how the tool works to produce its output How Point Density works—Help | ArcGIS for Desktop

I just figured out what was confusing me. I'm not terribly familiar with Arc, and what was happeneing was the 0 value was creating a non-transparent color. When I set 0 to be transparent it fixed it.

Thanks for the help.
