Lots of datasets were updated in March and April this year, with the majority of updates being to data in the Ordnance Survey Collection of Digimap. We also updated the vector marine data in Marine Roam so that it is now displaying the same version that is available for download through Marine Download; the Borehole data in Geology Download has also been updated to the latest version.

The updates include the latest versions of the 1:50,000 and 1:25,000 Colour Raster products which show the new height of Ben Nevis. The mountain, which is the tallest in Britain, was recently resurveyed by OS and found to be one metre taller than the measurements taken during the previous survey in 1949. If you’re interested in finding out more about the resurvey, and why two different heights are shown for the summit on the maps, the Ordnance Survey have published a blog post which explains the process in detail.

The tables below detail all the datasets that were updated recently in each Collection along with the publication dates of each one.

* Note: these are the last updates to OS Street View, Merdian 2 and Strategi that will be supplied by Ordnance Survey who have announced that they are retiring these products. Whilst the data will still be available to download through Digimap, these products will no longer be updated to reflect changes in the real world.

The data product updates help page is kept up to date with all dataset updates in the Ordnance Survey collection.

 

Marine Roam:

As well as all the changes in the Ordnance Survey collection, we have also updated the vector data in Marine Roam from Seazone Solutions. This brings the data up to date with the latest version of the product from SeaZone Solutions, which is also available for download through Marine Download.

Product Name SeaZone Publication Date
HydroSpatial One August 2015

HydroSpatial One showing Leith harbour

 

Geology Download:

Finally the Borehole data available in Geology Download has also been updated to the latest version available from the British Geological Survey.

Product Name BGS Publication Date
Onshore Borehole Index January 2016

In January 2016, the Marine Maps application available through Marine Digimap will be replaced by a new application called Chart Roam.ChartRoam-overview

As it’s name suggests, the new application will offer the same Chart data currently available through Marine Maps.  SeaZone (the data supplier) now call this dataset HydroView Charts.  They were previously referred to as the Charted Raster data.

Chart Roam will operate in the same way as all other Roam clients available, offering slippy maps, 12 fixed scale map views, annotation and measurement tools, as well printing in multiple file formats and sizes up to A0.

A date for release will be advertised in the new year.

If you have any questions, please do not hesitate to contact EDINA on edina@ed.ac.uk.

Money and Calculator

Image Courtesy of Images_Of_Money

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

Digimap Screen Maps Made 2010 to 2014

No monetary values were assigned to the millions of screen maps that are produced from Digimap.   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:

We are currently offering free trial access to the new Marine Roam facility to institutions which do not yet subscribe to Marine Digimap.

Marine Roam provides the only available online mapping tool for Hydrospatial data, a comprehensive dataset of features found in the marine environment, including buoys, wrecks, windfarms, sandbanks, flora and fauna, as well as transportation and socio-economic use information. Marine Roam is currently available as a beta service.

Any staff member at a UK Higher or Further Education Institution can request a free trial. EDINA will issue one username and password per institution which may be shared with anyone at that institution wishing to try the facility. Passwords will be valid until 31 March 2011.

Please feel free to pass this message to others who may be interested or request your trial account.

Request a free trial now

Information regarding how to subscribe to the Marine Digimap resource can be found at – http://edina.ac.uk/digimap/access/ a subscription provides access to data download facilities as well as online mapping.
