  • Photos Queen Victoria Street, near Bank, 10 May 1941
  • Accuracy bomb destroying Central Line ticket hall at Bank Station
  • Accuracy point locations sometimes slightly off, georeferencing of images not perfect
  • Geocoding accuracy historic data using modern dataset - close to More London Place, street name changes over time, etc.
  • Responsive site, perfect for tablets, smartphones, etc.
  • Android app
  • Augmented reality
  • ~70 global media reports 7th December - 185,000 unique visitors (~6 per second at peak) 380,000 unique visitors since launch

The Project•Mapping the London WW2 bomb census between 7 October 1940 and 6th June 1941•Maps previously only available in the Reading Room at The National Archives•Making the maps available to citizen researchers, academics and students wanting to explore where the bombs fell and to discover memories and photographs from the period
    5. 5. Main Features•Creating digital maps of the bomb census•Creating bomb location data (CC-BY-NC)•Spatial analysis within different boundaries•Combining with geolocated stories and photos•Creating web-mapping application•Creating a mobile application

    15. 15. Project Outcomes• Georeferenced bomb maps, digital record of national importance• Final data shared with The National Archives; reduce use of the original maps and aid their preservation• Opening up maps – increasing accessibility; remove need for specialist skills to prepare and process data; only need to do things once• Geographic framework for study of impact of bombing; aiding understanding of social/economic impact, post WW2• Augmented reality app not just for academic use; the power of geography
    16. 16. Still to Come•Download datasets for non-commercial use (Spring)•Tutorials on using the site (Summer)•iOS mobile app•& more work... (if we can find funding)
