This seamless historic map can be:
- embedded in your own website
- used for research purposes
- used as a backdrop for your own markers or geographic data
- used to create derivative work (such as OpenStreetMap) from it.
The mapping is based on out-of-copyright Ordnance Survey maps, dating from the 1920s to the 1940s.

How to display the historic map in your mobile device or phone (including the Apple iPhone, iPad or Android mobile)
The map can be directly opened in a web browser by opening the Internet address: http://nls.tileserver.com/
The map is ready for natural zooming and panning with finger pinching and dragging.
Instead of typing the address you can also point your mobile's camera to this QR Code:
If you open the address: http://nls.tileserver.com/?q=auto, your mobile will detect your current position. The map display will zoom to the current location where you are.
You can also create an icon for this historic map in an iPhone. Press "+" and then "Add to Home screen" and this historic map will be instantly available, just like other standard iPhone applications.
How to embed the historic map in your website
- The easiest way of embedding the historical map in your website is to copy < paste this HTML code into your website page.
Simple embedding (try: hello.html):
You can automatically position the historic map to open at a particular place or postal address by appending the name as a "q" parameter - for example: ?q=edinburgh
Embedding with a zoom to a place (try: placename.html):
- You can automatically position the historic map to open at particular latitude and longitude coordinates: ?lat=51.5&lng=0&zoom=11. There are many ways of obtaining geographic coordinates.
Embedding with a zoom to coordinates (try: coordinates.html):
- The map can also automatically detect the geographic location of the visitor to display the place where you are right now, with ?q=auto
Embedding with a zoom to coordinates (try: auto.html):
How to use the map in a mashup
The NLS Maps API exports a public function
NLSTileUrlOS() for accessing the map tiles for the Ordnance Survey map from 1920-1947:
We have prepared simple examples of use of our API - which you can study and copy<paste into your mashups.
- Usage with Google Maps API:
Example of a separate map available under separate "Historical" button: google.html
Overlay of the Google base maps with changeable transparency: googleoverlay.html
- Usage with Bing MapsSDK:
Overlay of the Bing base maps: bing.html
- Usage with OpenLayers:
Separate layer in Openlayers: http://nls.tileserver.com/openlayers.html

The only condition is that you must display an attribution to the National Library of Scotland, together with a link to our website, whenever our map is used. If you create derivative work, the documentation of your work must contain this attribution.
The primary intention behind creating this map service is to promote the use of historical maps in online mashups.
We are following the OpenGIS WMTS REST standard. The tiles are compatible with other popular online maps, such as the Google Maps API, Bing Maps SDK or OpenStreetMap, and are in the Spherical Mercator projection.
The service is normally available 24 hours a day, but the National Library of Scotland cannot be held liable if the site is unavailable at any time, for any period, for any reason.
Which map series are used
We have chosen recent out-of-copyright Ordnance Survey map series that we have complete coverage of. We plan to add more map series to improve the user experience while zooming.
At present the seamless historical map is composed of map sheets from these Ordnance Survey map series:
- 1:1 million, Great Britain, 1933
- Quarter-inch to the mile, Scotland, 1921-1923
- Quarter-inch to the mile, England and Wales, 1919-1921
- One-inch to the mile, Popular edition, Scotland, 1920-1930
- One-inch to the mile, New Popular edition, England and Wales, 1945-1947
How the seamless map was prepared
We have scanned paper map sheets of out-of-copyright Ordnance Survey maps. All the individual map sheets were cropped to remove their margins and then georeferenced in the OSGB coordinate system. They were then combined together to create one zoomable seamless map for Scotland, England and Wales. We intend to add Ireland in the future as well. The tiles were prepared with a customized version of the MapTiler application and the map was rendered on the Amazon EC2 computer cluster by Klokan Technologies GmbH. The tiles are hosted at TileServer.com.
