(Archived) [App] EnschedeLocator Beta, Offline map and simple navigation in Enschede for Android
Two weeks ago, a friend and I visited the OpenData Enschede Hackaton. The municipality has a project making a platform for serving data to the public, an overview of the datasets can be found here.

I discovered OSMDroid which is a library that aims to be an opensource alternative to Google MapView in Android.
