Greetings Everyone,

I keep thinking I am adept at knowing this program, but I keep finding new ways to get confused.

Key Points:

1. my spatial coordinates are in degrees, I geocode using whatever free tool I can find online
2. I am trying to create a heat map using spatial analyst density kernel density
3. I know I have to reproject my data from degrees to something with meters
4. I know I can do this on the fly with the environments button in Kernel Density tool
5. In the Kernel Density tool I set things up thusly

Input point or polyline feature:
mydiseasedata (this is in degrees GCS_WGS_1984)

Population field:

At this point I go to the environments button in the kernel density

I select Output Coordinates

Output Coordinate System

As Specified Below

In the box below as specified below, I selected WGS_1984_Web_Mercator_Auxiliary_Sphere

Geographic Transformations

I leave this blank

Then I hit ok

Now we are back in the Kernel Density tool

I hit ok

Then I get the classic Error

Kernel Density [080248_05202014]
Output raster: <empty>
Error 010092

Guys I need some help here.

I have been through every YouTube tutorial and ArcGIS thread on this issue. Everyone says I need to transform on the fly and I think that is what I am doing, but I must be doing something wrong.

Any assistance?
