In March 2017 Ordnance Survey withdrew the Meridian 2 dataset from their portfolio. Â It remains available within Digimap, but has moved within the Data Download application from Vector Data to the Withdrawn Datasets category. Both national and tiled coveragesÂ are still available here.Â Documentation about this dataset can also be found in the help pages: Meridian […]
EDINA will be running a free webinar about Aerial Digimap on Wednesday 25th January at 13:00 – 13:30pm. Please join us to learn more about Aerial Digimap and the benefits the data can bring to research, teaching and education. The webinar is free, but you will need to register (see link below).

We have identified a problem with all print maps generated from Chart Roam.Â 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.Â The error applies to all map sizes and all print scales, to a greater or lesser extent.Â 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.Â 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.
As it’s name suggests, the new application will offer the same Chart data currently available through Marine Maps.Â SeaZone (the data supplier) now call this dataset HydroView Charts.Â 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 email@example.com.
We are often asked whether maps from Digimap may be used in submissions for planning applications.Â The answer is no.Â This applies to ALL planning applications, regardless of who submits them, to which authority and under what guise.Â This includes:
- students submitting planning applications to a planning authority as part of coursework or work placement schemes
- all private planning applications (commercial or residential)
- institutions submitting planning applications for their own premises
- members of staff who take on consultancy work involving the submission of planning applications
Maps and plans for planning applications can be purchased from many different suppliers. Promap is one such example.Â There is also a UK government website called the Planning Portal which can assist with plans and maps.
We are often asked whether Ordnance Survey maps from Digimap can be published on the web and whether the Digimap licence allows this. The simple answer is yes, but there are (as always) caveats. The most obvious one is that any maps from Digimap that you publish on a website must relate to your academic work. That applies to the use of Digimap, regardless of what you do with the maps or the service.
The section of the Ordnance Survey Licence you need to look at is Schedule 2 of the Second Variation Agreement. This was originally called Appendix 4 under the original 2007 – 2009 licence, but has since been superseded by the first and second variations. You can find all the licence documents online here:
If you wish to publish a static image on your public-facing, “open to the world” website, you may do so on condition that the image is no bigger than 1 048 576 pixels. This is the equivalent of a square 1024 x 1024 pixels.
If you wish to publish a static image on an intranet page, that is, a website with access restricted to members of your institution, there are no restrictions on the size of the image you can use.
You can publish as many images as you wish, as long as each one is less than 1 048 657 pixels (1024 x 1024 or equivalent).
A more common and complex question is whether you can put up a “zoomable” map with your own data overlaid on it. If this is what you wish to do, you need to consider the following stipulations in the licence:
When rendering mapping on a website:
- Only Digital Maps may be published. Digital Data and mapping in GeoPDF format may not be published at any time.
- It must only be available as an image and not be accompanied by drawing or measuring tools.
- It is permissible to zoom in and out to enlarge or reduce the viewing scale of a discrete map image but not to change from one dataset to another of higher/lower resolution.
- It is permissible to pan to the edge of a discrete map image (where the ‘viewing frame’ is smaller than the overall image).
- Digital Maps may be displayed at any size on screen.
- More than one Digital Map may be included but no single Digital Map may be of a size greater than specified above.
Note that “Digital Maps” is a capitalised term and is specifically defined in the licence agreement. The definition given is: “any or all of the maps created by a Datacentre from the Licensed Work to be used in a Service provided by a Datacentre.” In essence this means any map created by Digimap which is “non intelligent”. That is, it contains no vector data, cannot be interrogated to extract data of any sort (in the same way as one might interrogate a satellite image to identify the spectral signature of a particular pixel), and is a dumb image.
Given these stipulations, you are not permitted to use the Ordnance Survey licensed data available through Digimap to display a series of maps using different OS data products which the public can zoom in and out of, pan around the whole country and add their own markers to, in a similar way to many other online mapping services (such as Google Maps or Apple Maps or OpenStreetmap). Note that this does not apply if you wish to use the OS OpenData, which is also available through Digimap.
Alternative Sources of Mapping
If you do wish to create an interactive mapping function on your website, you might like to consider the alternatives to using licensed Ordnance Survey data. EDINA operates a free service called OpenStream which provides OS OpenData through an API. You need an academic email address to register for OpenStream (ending .ac.uk) , but it doesn’t cost. The maps area available under the OS OpenData licence and the licensing terms are therefore much more flexible than the data licensed through Digimap.
As ever, if you have any questions about what you can and cannot do under the Digimap licence, please do not hesitate to contact EDINA with details of what you wish to do, what data you wish to use and who you intend should benefit from your work. We are keen to hear of licensing questions you would like to see explained further on this blog.
Since the addition of new print functions to Roam, it is now easier to print a map showing the whole of Great Britain.
- Log in to Digimap and click on Roam in the Ordnance Survey Collection.
- Use the slider bar in the upper right corner of the map to zoom in once to show the National View. Don’t change the position of the map itself.
- Click the Print button on the top toolbar (top right hand corner)
- Set the print scale to 1:1.1 million (1:1100000)
- Choose A0 portrait and an appropriate format from the drop-down lists (PDF will generate reasonably quickly)
- Now click-and-drag the preview map directly upwards (north) so that Arbroath (shown on the east coast of Scotland) is at the very top edge of the preview map.
- Click Generate Print File
- The resultant file in PDF format will be around 2.9MB
If you prefer to use a different map product, you could use the following variations on the above instructions:
- Zoom in twice on the map using the slider bar (to view the County View map). Again, don’t change the location of the map.
- In the print interface, set your scale to 1:1,100,000 and your paper size to A0 portrait, as previously
- Now drag the map northwards so that the town of Lauder sits just below the top edge of the preview map.
- This file in PDF format will be around 11MB
These instructions may need some minor alterations depending on your monitor resolution. You may find you need to drag the map either a little more or a little less further north in order to see both Shetland and the Scilly Isles on your printed map.
The functionality and datasets offered by MasterMap Download and Boundary Download are now available through the standard Data Download application. This can be found in the Download OS mapping data section of Digimap’s Ordnance Survey Collection.
This means that both MasterMap Download and Boundary Download will be withdrawn at the end of May 2013.
If you have teaching materials or course notes which are currently based on the old MasterMap Download and Boundary Download applications, please make sure you update them before these facilities are withdrawn.

Geologists and others with an interest in Hutton’s Unconformity might be interested in a statement by The Geological Society regarding a proposal to construct a pump house and pipeline 150m to the east of the SSSI area at Siccar Point:
You can see some photographs of Hutton’s Unconformity at Siccar Point by logging in to Geology Roam and searching for “Siccar Point”. Zoom in to the largest scale map and click on the Geological Photos button above the top right hand corner of the map. Then click on the camera icons on the map to see each photograph.
