Easier fault reporting

Local Authorities throughout England and Wales are moving their services online following reports on the reduced costs per transaction for this form of contact. In moving transactions online it is essential that the application is easy to use and provides an effective means of transferring information to relevant departments efficiently. The London Borough of Haringey achieved just this by integrating the National Land and Property Gazetteer and National Street Gazetteer as the source of locational information in their new system that provides members of the public with the ability to report and "pin-point" the location of a problem on to an online map. Follow the link in the title to read more about this integrated use of the NLPG and NSG and the benefits that can be gained.
