The Great Britain Historical GIS team at the University of Portsmouth, working with Klokan Technologies, are very pleased to announce that the Old Maps Online federated search portal for historical maps is now live, and available for everyone to use:
www.oldmapsonline.org <http://www.oldmapsonline.org/>
At launch, the portal covers five collections, and a bit over 60,000 maps:
A Vision of Britain through Time
British Library
David Rumsey Collection
Moravian Library
National Library of Scotland
The portal covers the whole world, and including the Rumsey Collection means
you will find something for everywhere. We are launching only four months into
a fifteen month project, so we have time to add more collections.
We already have several additional map libraries which will definitely be
added, but we are looking for more.
To be included, maps must have been scanned, obviously, and they must be
directly accessible online without payment or passwords. There is no need for
the maps to be in any particular viewer, but we need to hold the real-world
coordinates of the corners; if you do not have these we can maybe help.
Although we have time to improve the site's software, it is already quite
polished and we want to keep it simple: this is aimed at the generality of
users, rather than either cartographic historians or GIS experts. Our aim is
simply to help users find maps, and pass them to the relevant library's site to
view them.
Our home page IS the search form, always displaying a map and usually
automatically centring it on wherever you are in the world. You can then
specify the area you want maps to cover, by zooming in and out, and panning
around; and also the time period you want the maps to be from.
As you change these settings, the system automatically updates its list of best
matches, and displays them as a scrolling list of thumbnail images to the right
of the main display.
Click on a thumbnail and a pop-up shows further information about the map.
Click on the thumbnail in the pop-up and a separate tab should open in your
browser, showing you the page for the map at the relevant library
-so for example, whether you can download the image depends on the library, not
on us. That is about all the portal does, but it hopefully does it very well.
