When Nottingham City Council released OpenData, a cautious approach to imports turned out to be beneficial. By exploring the data we discovered new ways to use it as an aid to mapping. Examples include: tracking construction of new tram lines; improving the detail of the city's cycle network; adding addresses and postcodes; checking alignment of streets; and mapping retail outlets. As OSM coverage tends towards completeness we discover a typical 2.5-5% error rate in government OpenData. Extending our approach to national or international level requires tools for fuzzy matching of OpenData with OSM data. Although such tools are not readily available the main requirements are now clear. I will illustrate these with reference to UK Food Hygiene OpenData.
