More mapping

Google's new Mapplets offering is a nice way to get going quickly with their Maps, I like its XML base. It prompted me once more to look, with more success this time, for something to translate our OSGB data to lat/long and I found this nice .Net project which has classes for back-and-forth translation as well as a SOAP interface. This should be good for either producing XML/KML data dumps or querying dynamically, with a little work. There are many potential uses for our geographical data and we are looking at ArcIMS's web service interface too, but this is hackable, could cut out an extra layer, and should let us offer data for people to mash up as they please.
