East Baton Rouge Parish has its share of buildings and sites on the National Register of Historic Places. I stumbled across a state website that displays addresses, maps, and pictures, but there wasn't an interactive map that showed all locations. (Wikipedia's article does link to one, but the coordinates are inaccurate.)
With the help of Google Maps' satellite view and a friend with access to scans of the National Register of Historic Places registration forms, I was able to find exact positions. Those of you who have a mobile device can now roam the streets in a more directed way to locate the historic places of interest to you. You can make the blue star () get closer to the pin you want to see next by just biking or walking in the right direction. The table of distances below this Google map will tell you what direction to head in and how far away the historic place is.
Below are the distances from your current location to each Historic Place. I've decided to let you manually select to start automatic updates of distances because updating each distance requires a separate query to Google. This can potentially eat up your mobile phone plan's allocated data usage, so it's up to you to turn that feature on.
I and other web developers have noticed that the functionality to locate the current position oftentimes fails with desktop browsers. This is a new technology and there are certainly still bugs in the way browsers perform this operation. Eventually, this will surely be fixed by the browsers and other third parties the browsers query.
Possible future functionality:
