Georeferencer: Help Us Find Locations
for Our Maps
Georeferencer is a new application added to our online library. It allows you to overlay historic maps on modern maps or other historic maps. The overlaid maps reveal changes over time and enable map analysis and discovery. You can choose your own maps to georeference by Searching LUNA or help us georeference the entire online map library using our Random Map link to open maps in our First Pilot Project. The video at the right explains georeferencing. The images below of Yosemite Valley 1883 show methods used. Users who georeference the most maps will be recognized in the bar displays below. The First Pilot Project will include over 10,000 maps of major cities and regions. Recently Georeferenced maps can be viewed by image or by location. See the Georeferencer Help page for assistance.

1. To get started, click on either the orange button below "Georeference a Random Map" or the "Search LUNA..." button. If you search Luna and find a map you want to georeference, open it in the zoom view window and click on the orange button "Georeference this map."
2. Enlarge the old and modern maps to find matching town names, street names or other places and assign common points to each maps. At least three points are required, and the more points you assign, the better the georeferencing will be. Use the search box in the modern map to find places listed on the old map. Spread you points over the largest possible area.
3. After assigning at least three points, click on the "Clip" button in the old map window to draw blue lines around the content area of the map (see video and Yosemite map above). The Clip lines should be just inside the border of the map.
4. When finished, click on the "Save" button above the modern map. The old map will then be overlaid on the modern map.
5. Chose 2D or 3D or Side-by-side views. When you have signed in (set up free account) and have some Favorites (either your own georeferenced maps or others you find in the Recently Georeferenced Maps display) drag similar location but different time period maps into the boxes above the map view and make comparisons with the transparency sliders.
6. For more detailed Help, see our Georeferencer Help Page and the Video above.
Klokan Technologies developed Georeferencer with the Moravian Library. You can combine and compare maps found at the Georeferencer pages at the National Library of Scotland and the British Library with maps from our collection in Georeferencer, just use your Login at those two online libraries Georeferencer pages and make Favorites of maps found there. Those maps will then show up in your Favorites list here and at those libraries as well.
