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.

We have identified a problem with all print maps generated from Chart Roam.  While the maps on the screen are displayed at the correct scale, when printed the scale is altered and on paper is not what was requested.  The error applies to all map sizes and all print scales, to a greater or lesser extent.  We would advise you to check any prints made from Chart Roam.

As a result we have temporarily disabled the print function in Chart Roam until we are able to implement a solution to the problem. Since the solution is related to third party software used within Digimap, we do not yet have a time-frame for resolution.  As soon as we have further information we will post it here.

In the meantime, we suggest that prints of the HydroView Charts are best obtained by downloading the required chart from Marine Download and printing the required section using alternative desktop software such as PhotoShop.

Apologies for the inconvenience caused.

Last week (3rd March) we released a new version of Digimap which includes a number of changes that may be of interest to our growing user base. Our set-up allows us to release new versions without requiring any downtime so the recent changes are highlighted below as they may not be obvious at first glance.

Greyscale versions of the 1:25,000 Colour Raster and 1:50,000 Colour Raster have been added to OS Roam

We have added greyscale versions of the 1:25,000 Colour Raster and 1:50,000 Colour Raster products in the Roam client of the Ordnance Survey Collection. These can be selected using the Basemaps drop-down.

Greyscale 1:25,000 Colour Raster with annotations

The new greyscale versions make it much easier to see your annotations on top of the basemap. The greyscale versions can be saved and printed like all other basemaps available in OS Roam.

Warning about losing changes in all Roam clients

If you customise a map in one of the Roam clients, for example by modifying the layers that are displayed or by creating annotations on the map, then press the browsers back button or navigate away from Roam you will now see a warning prompt advising you that you may lose your changes. The prompt that is displayed in Chrome is shown below:

Confirm navigation

The prompt is not displayed if you have saved the map, printed the map, or exported the annotations.

Updates to the Open/Save wording in all Roam clients

We have updated the text on the Open and Save menus in all Roam clients to make it clearer what each option does:

Roam Open drop down

Open > Saved maps allows you to open any maps you have previously created and saved within Roam.

Open > Import annotations is where you go to import external datasets in to Roam (we currently support the import of datasets in Shapefile, KML, GPX, CSV, and GeoJSON formats).

 

Roam Save drop down

Save > Save map will save the current map extents along with any annotations to Digimap for retrieval at a later date.

Save > Export annotations allows you to export annotations from Roam as an external dataset for use GIS/CAD (we currently support the export of datasets in Shapefile, KML, and GeoJSON formats).

 

Background mapping in Data Download of all Collections is now shown in greyscale

The background mapping data in all Data Download clients has been converted to greyscale:

This makes it much easier to see the availability and reference grids in these applications.

We released a new version of Digimap last week (2nd February) which included a number of improvements to the service. Whilst we try to minimise downtime during releases some users may have noticed some of the new features; in this post we’ll highlight the changes that affect Digimap users.

Chart Roam

By far the biggest change happened in the Marine Collection where the old, somewhat dated, Marine Maps application was replaced with the new Chart Roam application. Chart Roam uses the familiar Roam interface to display hydrographic charts, enabling users to quickly and easily navigate around using the tools they are familiar with from other Roam clients.

New Chart Roam Interface

Updated Roam Measurement ToolsChart Roam displays marine Hydrographic Charts from SeaZone Solutions using the WGS84 Web Mercator projection. As part of the work done to support the display of map data in different projections we added Nautical Miles to the distance measurement tool in Chart Roam. Users can now measure distances in metric (metres and kilometres), imperial (yards and miles) and nautical units; areas measurements can only be made in metric units at present.

Annotations [all Roam clients]

We have made significant improvements behind the scenes to the way annotations are handled in all Roam applications. This work was done to ensure that users uploading annotations with a large number features can style, save and print the data once loaded in to one of the Roam applications. Other notable improvements are detailed below:

  • We have added the ability to load multiple Shapefiles as annotations from a single Zip archive. Previously it was only possible to import a single Shapefile from a Zip archive, and all other Shapefiles were ignored by the import process. Now all Shapefiles in your Zip archive will be added to the map, and they can be of different geometry types e.g. points, lines and polygons.
  • We have improved the printing process so that it is possible to create prints that contain many more annotations.
  • Improvements have been made to remove some of the internal file size and feature number limits when loading, saving and exporting larger annotations. Note there is a 10MB file size limit when importing annotations.
  • Annotations in CSV (comma separate value) format can now be imported using Latitude and Longitude values; previously it was only possible to import CSV annotations in the British National Grid projection.

Ordnance Survey Roam

A number of changes have been made to the Ordnance Survey Roam application, predominantly to rationalise the data available at the different zoom levels:

  • The vector version of VectorMap District (VMD) has been added to OS Roam and is available at the Local View zoom level (approx. 1:19,000) as an alternative map accessed through the Basemaps option:
    VectorMap District Basemap
  • The Local Plus View has been removed and the datasets available in the District and Local Views have been rationalised. Full details of the datasets available in each View can be found on this help page.

Accessing Product Help [all Roam clients]

As well as updating the help pages to cover the changes listed above, we have also changed the Map Information panel in all Roam clients making it easier for users to get help on the particular map product(s) they are currently viewing in the map window.

  • Hyperlinks to help pages for each product have been added to product names in all Roam clients. The screen grab below was taken from Geology Roam where the hyperlink takes the user through to a help page dedicated to the map product currently displayed in the map window (DiGMapGB-50 Rock Unit):

A number of datasets have been updated in January in both the Ordnance Survey and Marine collections.

We reported back in December that the new ‘No Marginallia’ version of SeaZone HydroView Charts were available to download through Marine Download. Since releasing this new version we have seen nearly 15% of downloads now requesting the new ‘No Marginalia’ version, which is great to see. Hot on the heels of this we have now made this new version available in the new Chart Roam application, which replaced Marine Maps. The ‘No Marginalia’ version was ideal for use in Chart Roam as the removed map marginalia means the charts are ideal for use in the slippy map interface in Chart Roam.

Money and Calculator

Image Courtesy of Images_Of_Money

EDINA has again calculated the commercial cost of all the data downloaded and maps created for printing in all Digimap Collections for the period August 2014 to July 2015.  This was done per subscribing institution  and then totalled; the grand total is approximately £77.25 million.  This estimate is a conservative one because we reduce the quantity of data downloaded by 60% to account for duplication of usage. 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 almost £128.5 million.

We know that some data is downloaded multiple times within an institution, for example by students during a class exercise or by individual researchers working on the same study site. 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 (i.e. fewer people downloading the same areas, for example, for the same study site), so we have included the 100% figure as a ceiling value.

In total, over the past five academic years over £435 million (£248 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. The upward trend in the total commercial costs has continued in 2014-15, though at a steadier rate, however we are seeing the same year on year growth in the number of logins to the service.

How the Costs are Calculated

Click to enlarge image

The costs used in our calculations for the data are sampled from the list prices published by a range of data suppliers, and include any relevant multipliers or discounts declared publicly on their websites.

Each data product is assessed individually because many are priced differently.  The obvious example is OS MasterMap, which is charged on the basis of the TOID density per square kilometre.  TOID density changes according to the area mapped. Each product is price-checked annually against a range of suppliers.

We calculate the values 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 2015

Click to enlarge image

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.  Many commercial service providers may charge an additional fee for this part of the service.

All OpenData products (both prints and data downloads) are excluded from the calculation, despite the advantages of producing them from Digimap over 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 spent submitting data requests and waiting for them to return; time to create and manage a repository for spatial data; time to acquire the knowledge on how to use the data you receive. Commercial providers mitigate these delays but may charge fees for the convenience.  By providing 24 hour access to high quality data, customisable maps and detailed support materials through purpose built interfaces, Digimap saves this time and expense for its users.

Digimap avoids students, academics and support staff having to wait longer than necessary for the information they need and the instruction on how to use it.

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 representative.  If you are unsure who your site representative is, please contact us:

A number of key datatsets have been updated in Digimap this December in several of the collections.

Of particular note are the updates to the Marine collection. The HydroView Charts raster product from SeaZone is now available in two versions: ‘Full Marginalia’ and ‘No Marginalia’. Users can select the version after adding the product to the basket in Marine Download.

Choose Marginalia in the Basket

The ‘No Marginalia’ version has all extra information round the map (e.g. north arrows, scale bars, inset maps etc.) removed and replaced with transparent areas. This makes it ideal for use in GIS software allowing you to pan across adjacent charts without this information obscuring the map data.

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.
