Congressional Maps web app

I’ve also been curious as to what old Congressional district lines look like, but even in the age of the internet such maps aren’t easy to come by.  Over the last few years, I’ve slowly amassed a collection of Indiana maps but had no good way to display them digitally in a uniform manner.  I’ve tried drawing them in Google Maps, but that’s a long, frustrating process.  I’ve found GIS coordinates for recent maps, but not all maps.

That all changed recently when I stumbled upon a random website and found a treasure trove: Every Congressional district ever drawn anywhere in the country through the 2011 maps. I was able to convert them into files that would work with Google maps, modify them to suit my purposes, and then build a version for our current map. After spending the last two weeks on this, I’m ready to unveil my new Indiana Congressional Maps web app.

You can zoom in or out, see the districts change from red to blue and back to red over time, click them to find out which member of Congress represented the area, and more.  Let me know what you think, and any suggestions you might have, at tf@capitolandwashington.com.
