Dynamic Mapping/Illustration Tool

Medium Priority
Last Modified: 2012-08-13
I am looking for a way to display information from database on a map.  For example, I want to take a map showing the counties within Michigan, Northern Ohio and Northern Indiana and shade each county according to the number of stores in each county (the more stores, the darker the color of the county).  

What do you suggest to do this?  I am using ASP and SQL Server.  I have used the Fusion Charts products in the past, but they do not have a tool to do this at the COUNTY level. The data is updated frequently, so it cannot be a static map; it must populate/render based on a live recordset.

Any ideas on  how to best accomplish this?
Watch Question

Have the map as a GIF file, in which each county has a separate color that is mapped in the GIF.

Then, on a request, read the GIF into memory as a binary, and edit the colors referring to the counties to the desired values. It needs a precise understanding of the color mapping in a GIF file. I don't have that, but that information should be findable somewhere.

Editing a binary on the fly in classic ASP can be done with the ADODB.Stream object.
