This document discusses mapping London at different zoom levels for the State of the Map 2008 conference. While the map looks complete at low zoom, issues are apparent at higher zoom levels, such as unnamed roads, incorrect junction layouts, missing roads under trees, and lack of footpaths and points of interest. The proposed solution is for mappers to dedicate Wednesday evenings to improving the map details through additional mapping work.
