As mentioned at Geoforum earlier this year, we’re currently working hard on a new version of Digimap Roam. The new-look application will bring Digimap Roam, the online mapping tool in the Digimap family, bang up to date with the latest web technologies available. Whilst the functionality will remain the same, the look and feel of the […]

New Digimap Licence Agreements
We are now at the start of a new academic year and Digimap has new licence agreements in place for the Ordnance Survey, Geology and Historic Map and Data Collections. You may have noticed already that you have been asked to agree to the licence again when you logged in. This is because some of the terms are different and you are required to agree to these new terms prior to accessing the data within the service.
When you login you will notice the Licence Agreements button at the top right of the home page.
Clicking on this will allow to you to view the licences you have agreed to and to agree to those you have not yet agreed to.
If a Collection has a new licence, the applications (e.g. Roam and Data Download) in that Collection will also appear grey. By trying to access an application which has a new licence, you will automatically be taken through the process of agreeing to it if you have not yet done so.
All you need to do is accept the licence and restate your purpose for using the service (which may or may not have changed since you agreed to the previous licence) and you will have access to the service once more.
If you have any questions or need any help or guidance have a look at the Agreeing to Licences for Digimap Collections section half way down the following help page:

Detailed contemporary mapping added to Ancient Roam
We have recently added detailed, large scale, contemporary mapping to Ancient Roam allowing users to compare side by side historic mapping with detailed modern mapping.
The detailed modern mapping is visible at all zoom levels in both the 1-up and 2-up views. The most detailed mapping uses the new OS OpenMap – Local product, which is the most detailed Open Data product available from Ordnance Survey and can be downloaded through the Digimap Ordnance Survey collection. We further enhanced the most detailed mapping to include the additional features from OS VectorMap District:
- Contours
- Spot heights
- Medical centres
- Police stations
- Heritage sites
- Places of worship
The other products we have added are OS StreetView and OS VectorMap District Raster to provide a comprehensive set of contemporary map data suitable for all zoom levels in Ancient Roam.
We hope you find the new data useful, if you have any questions about the updates or Digimap please contact us:

Digimap 2013-14 Print Maps & Data worth £65.4 Million

As part of our work to demonstrate the value for money of the Digimap Collections, EDINA has calculated the commercial cost of all the data downloaded and maps created for printing. We calculated the values per institution for the period August 2013 to July 2014 then totalled them; this came to approximately £65.4 million. This estimate is a conservative one because we reduce the quantity of data downloaded by 60% to account for duplication. When all the maps printed and data downloaded were included in the calculation (i.e assuming users would continue to take their own data and maps, and not share them) this total rises to over £107 million.

We know that some data is downloaded multiple times within an institution, for example by students for a class exercise or by researchers for specific study sites. We found that on average only 40% of the data taken from Digimap over a period of time was unique within an institution. We believe that if institutions were paying commercial rates for their data they would be more likely to download it once and circulate it to those who need it; this is why we reduce the amount of data included in our calculation. However, there is considerable variation between institutions as to how much is unique; those that do more research or are smaller in size tend to have a greater proportion of unique downloads, so we calculated the 100% figure as a ceiling value.
In total, over the past four academic years over £306 million (£170 million at 40%) worth of print maps and data has been served up from Digimap to subscribing institutions. The steep increase in 2013-14 was caused by more Ordnance Survey products being downloaded and printed than ever before and also by the high commercial costs of several products added to the Geology Digimap service.
How the Costs are Calculated

The costs used in our calculations for the data come from the list prices published by data suppliers, and include any relevant multipliers or discounts declared publicly on their websites.
The data costs we calculated are done on a per product / per institution basis, with the data preparation and licensing charges assigned only once per product, per institution (rather than per data request). Many of the data collections are commercially licensed based on the number of users who have access to the data; with increasing numbers of users a multiplier is applied to a base cost. We applied the relevant multipliers according to the number of active registered users for each Collection at an institution.
We capped data costs at the price of national coverage for each product, making it impossible to assign greater cost for any one product than it would be to supply the entire dataset for use by a whole institution.
The values for the print maps (including saved maps in all Roam applications) are calculated by finding the cheapest commercially available map prints from websites such as eMapsite, NLS and FiND.
What We Didn’t Include
Click to enlarge image
No monetary values were assigned to the millions of screen maps that are produced from Digimap. Â The value calculated also doesn’t take into account any of the help materials, training courses and support facilities that are all part of the Digimap service.
No OpenData downloads or maps created from OpenData are included in the calculation, despite the advantages of producing them from Digimap rather than other websites.
However, the biggest saving that isn’t included in these value calculations is your time. We only charged the data supplier’s preparation and licensing costs once per product or order, in line with each company’s policy where it applied. In reality there would be many orders occurring throughout an academic year as new research questions are raised. This all costs time, time which the data suppliers will charge for or that institutional staff would have to take to submit requests for data and time for staff to create and manage a repository for spatial data.
With 24 hour access to high quality data and maps through a purpose built mapping and data download interface, Digimap does all this work for its subscribers.
Over the coming weeks we will be sending out each institution’s data cost calculations to Digimap site representatives. If you are interested in the commercial costs of the maps and data your institution has been using please contact your site represenative. If you are unsure who your site representative is, please contact us:

Historic Digimap: Printing options improved
Ancient Roam in Historic Digimap has had its print options updated so it now has the same set of options as the other Roam facilities. The two big changes to note are that you can now print up to A0 and that you can print a single county in areas where several overlap.
Until this change was made it was impossible to print an area with overlapping maps without printing all the counties available rather than just the one(s) you were viewing on the screen. Any print files now generated in areas with overlapping counties will only show those which are displayed on screen. This allows you to have the control over how much information is on your map and to make the decision to show more or less information.
Sometimes it can be an advantage to show multiple counties as even though the sheets overlap the actual map information doesn’t. However in the example above you can see how the counties overwrite each other in the map on the left and so produce a very confusing and fairly useless result; by switching one county off you can produce a much clearer print map such as the one on the right. [Click on the images above to view larger versions of the maps.]
The ability to print maps up to A0 brings Ancient Roam into line with the other Roam facilities so you can now print at this very large size in any Digimap collection.
