Although there are some questions about how useful the Census Voting District Maps are for our purposes, they seem to be the only available shapefiles I can find, so I'm going to run with them until we find something better.
The Secretary of State's office hosted the Auditor's pages for a while, at least long enough for Google to grab cached copies of them. Good enough for us.
First step, download the voting district map. Open that up in MapWindow GIS. Go to Color Scheme, and set the attribute to County, and give a red color to any shape where county = 001, meaning Adams. Here is the result:
I'm trying to figure out how to open and manipulate the .dbf file that comes with shapefiles. I've tried OpenOffice Calc, and I can open the file and change it, but when I save it the format gets screwed up.
