Well, for the brave, criminally insane, curious, or otherwise bored I have a alpha version of Historical Buildings – download the APK if you want to try it out. This is just, at this time, the application just shows a simple list of historical buildings in Edmonton (according to the City of Edmonton’s Open Data Catalogue). Click on a building, and it will show you on Google Maps where the building is in the city. The code for this is, in my opinion (and to say the least) – rough. But it is a start. Definitely needs some improvement. Or maybe I just need to change my thinking to more of a Android/Java mindset. Anyway the usual caveats apply: use at your own risk / batteries not include / do not eat / void where prohibited by law, etc, etc, etc
