How to use ArcGlobe to extrude a feature that is not an elevation?

I have an Excel spreadsheet that has county names as the rows and two columns of measured data: crime rate/1000 residents and the modal age of the citizens. I would like to create a map of the counties with a graduated color map expressing the crime rate and the elevation of the map corresponding to the modal age in the county. I have tried to follow the directions given in the ArcGis 10.2 desktop Help section but without success. Any advice on how to accomplish this will be will appreciated.
Thank you.

Hi Justin,

The first step will be joining the Excel data to your featureclass with the counties. This featureclass will than have for each county the crime rate and modal age. Next you load this featureclass into ArcScene and follow these steps:

1) symbolize the data using the crime rate (use graduate symbols)

[ATTACH=CONFIG]28680[/ATTACH]

2) Set the extrusion based on the modal age

[ATTACH=CONFIG]28681[/ATTACH]

Please note that I multiply the value with 100 to make the extrusion (in meters) visible.

3) you can additionally change the vertical exaggeration (in my case 10x) of the data frame. Double click on the data frame to open the data frame properties:

[ATTACH=CONFIG]28682[/ATTACH]

This will give the following result (using Ohio counties and fake data):

[ATTACH=CONFIG]28683[/ATTACH]

Please note that there will not be much variation in modal age (hence the exaggeration), while using the crime rate as extrusion may give a more appealing image.

Kind regards,

Xander

Thank you Xander but when I follow these logical steps in ArcGlobe I create a globe without mapped features instead of the surface that you have and I would like to create. How to I switch from a globe display to displaying the U.S. with the county boundaries shown (as my data will create when used with ArcMAP), the counties then colored according to crime and elevated, as you show, by modal age of the population X 100?
Much Appreciated.

Hi Xander:
I regret having to ask as I suspect the answer is obvious yet it has escaped me. When I follow the sequence of steps that you outlined, I get a globe rather than the desired surface that you obtained. How can I switch from the generic globe that appears when ArcGlobe begins to the surface display of the USA that you were able to achieve?
Thank you for your consideration,
Justin

Hi Justin,

I used ArcScene for this purpose and not ArcGlobe. The curvature of the earth willl be more visible when the eare you visualize increases. I just used the counties of Ohio which I downloaded from the Internet.
