title: Is there a free maps API like Bing/Google maps that can be used in internal applications
body: <p>The licenses for both of the above allow certain free use but not for my requirements. I need a map API that can be used to find a place by postcode, then narrow down the position of a specific building to obtain the lat/long. The customer doesn't technically need this but it will make the locating of their store lat/longs easier. The very low usage involved doesn't warrant a paid subscription, as we are expecting up to 25 store position look ups per year.</p>
  
  <p>Will be using the solution from WPF, though a browser-based option is fine.</p>
