I've now had updated map files through from NLS and these work well. The main priorities now are:
* Website - we need to think about the design. I've just raised this with Chris at the NLS to get his thoughts (it is after all their maps at the moment). * Improving the vectorizer so that we don't end up with a gap between terrace buildings. Help from the GIS community would be great.
