Interactive maps can be really effective ways of visualising information with a geographic compotent. For example, if you want to find participation workers near you making use of Hear by Right, the Local Network Map lets you see who is around far easier than any listing would.

Up until now, finding out the co-ordinates of a UK address to be able to plot address-linked information onto a map either meant paying a lot to commercial providers for access to a postcode or address database that could tell you - or putting (as the HbR Local Network Map does) with being accurate to within one or two miles by using free postcode databases and geocoders.
