At 11:00 am access to Digimap Carto will be closed and by 12:00 noon it will have made its last map. Carto was at the cutting edge of web mapping technology for several years, delivering Ordnance Survey maps to thousands of users while Google was still just a search engine.  The high quality EPS and then PDF print files it produced meant that staff, students and researchers could print out maps of anywhere in Great Britain and were no longer limited to their library’s collection.

How Carto has changed since 1998

Carto over the years 1998 to 2013

As time passed Carto could easily keep up with the latest offerings from MultiMap (later bought by Microsoft and eventually becoming Bing Maps) and Google Maps. It had more advanced tools and much better data in the form of OS MasterMap, so as the Java updates got more frequent we all put up with the software being a bit unreliable for a few days before we could issue a fix. However after 2011 the number of Java updates ramped up significantly and the changes became more difficult to accommodate. Once anti-virus software began seeing Carto as a potential threat and preventing it operating we decided that maintenance was unsustainable.

EDINA realised that continuing to support Carto would be too costly in terms of developer time spent fixing problems rather than improving and enhancing the service. In the meantime the rest of the world had become much more accustomed to viewing maps online in a web browser; EDINA’s other mapping service, Roam was able to take on much of what Carto was offering without confusing or frustrating its users.

Some recent changes to the capabilities of the web mapping platform that Roam uses meant that we could finally offer a Carto replacement without the need for any software to run on the end user’s computer. These changes have allowed us to withdraw Carto and let Roam to take on all the mapping duties for Digimap. We can now get on with the business of all those improvements and enhancements we have been wanting to make. We hope you will like the changes that we are aiming to have in place this August:

Farewell Carto!

For those of you using Internet Explorer (IE) version 10, you may have noticed that the maps in Roam can get muddled up. This browser is standard for Windows 8 and is also available as an upgrade if you are using Windows 7.

Muddled maps in IE10

The error is caused by the underlying technology EDINA uses to put the maps into your web browser.  A patch for the particular piece of software that causes the issue has been released and we are now working to incorporate this into Roam.

Until this fix has been released you can prevent the error from occurring by switching IE 10 to run in IE 9 mode. To do this simply press F12 on your keyboard when you are using IE 10 and change the Browser Mode: to Internet Explorer 9.  The image below shows how this is done:

Changing IE10 to IE9 Mode

Click the image to enlarge it.

This issue affects all the different Roam mappers, Digimap, Ancient, Geology and Marine, however all will be fixed by making the change to the browser mode.

If you have any questions about this or any other issue with the Digimap services then please get in touch:

We have introduced a raft of new print options to Digimap Roam;  some of these were previously only available in Carto, others are new altogether:Select your print scale in Digimap Roam

Select your own scale for the printed map (within sensible limits)
Print OS MasterMap at up to 1:100 scale (Carto’s limit is 1:500)
Print at paper sizes up to A0
Print landscape or portrait orientations (not available in Carto)

The new print options along with the formats already available mean that printing from Roam is now more flexible and powerful than Carto.

We have also added an extra zoom level to Roam’s screen maps called Building View. This shows OS MasterMap at around 1:500,  making it easier to add detailed annotations such as new buildings to your map.

Scales shown are the default print scales, screen map scale varies depending on the pixel size of your monitor / device.

With these enhancements Roam can now perform many of the tasks previously only possible with Carto.

Unfortunately, Carto has become difficult to maintain and needs to be replaced. These changes to Roam, along with some extra features planned for the coming months, will enable it to take the place of Carto. Once all the enhancements to Roam are made we will retire Carto completely; we intend to do this at the end of July 2013.

If you have any concerns about the withdrawal of Carto then please let us know:

Marine Roam is a fantastic service which provides access to SeaZone HydroSpatial data for the waters around Great Britain.  There are many applications for the data and the expanding offshore renewables sector, and associated research around it, immediately springs to mind.  However, did you know that you can use Marine Roam for some historical sleuthing?

70 years ago today, 27th march 1943,  HMS Dasher was sailing up the Firth of Clyde heading for Greenock.  HMS Dasher had been converted into an aircraft carrier and was home to 8 Swordfish and 2 Sea Hurricanes. The planes were being refuelled following landing practice when there was a series of massive explosions.  The ensuing fire could not be contained and the ship was abandoned. It sank just 6 minutes after the first explosion. While 149 seamen were recovered, 379 lost their lives.

Wrecks are marked in the HydroSpatial data and can be queried in Marine Roam.  It is a little tricky to find the wreck of HMS Dasher.  I knew it was situated in the Firth of Clyde, mid-way between Arran and the mainland, about 5 miles south of Little Cumbrae. However, the only wreck I could find was that of the Antares, a fishing trawler which sank in 1990 after its nets were apparently snagged by a submarine.  After a bit of hunting I found some strange boat shaped features, seemingly related to military wrecks which for the most part appear to have been sunk during exercises.  One of these marks the resting place of HMS Dasher. Below is a screenshot of the attribute information held in the HydroSpatial data about her.


Wreck of HMS Dasher in Marine Roam

You can log into Marine Roam and use the Info Tool to explore features on the map. Alternatively, you can download the data through Marine Download and load it into a GIS for further exploration.

So what other famous ship wrecks can you find in Marine Roam?  Why not post a comment with the coordinates of your favorite sea-floor find.

Much of the background information used in this blog post was taken from the fantastically detailed records available through the Royal Commission on the Ancient and Historical Monuments of Scotland website.

We have been having a play around with the new annotation tools in Digimap Roam here at EDINA, and have come up with a few things you might like to try.

Firstly, you will have no doubt been adding many new features to maps but have you tried taking some away?

A farm shown in Digimap Roam

This is the original map area, a MasterMap map showing some large farm buildings to the left of the original farm house. If you had some information about how the area looked prior to their construction you could recreate a map form the past.

The map on the right shows the area after a large green polygon has been drawn over the building area.  Make sure you select an appropriate line width and style for the map, and remember to set the opacity to maximum. You needn’t stop there though, you could add buildings on top of the green polygon representing those that had existed previously.


You can also use the annotation tools for some other neat tricks.  The image below shows how you can trace around existing features, a car park in this case, and use the measurement tool to work out its area. By making the polygon fully transparent you can then print out your result without obscuring the original features.

Finally you can use multiple lines and polygons, annotated with text to build up complex new features on the map. The example below shows a proposed new airport in the Thames Estuary:

Digimap will be ‘at risk’ between 17:30 and 18:30 on  May 17th to allow for some service changes and improvements to be made. Access to the service will have to be disrupted intermittently during this period as we add in some new features and make some software upgrades.  We apologise for any inconvenience caused and hope that you find the new additions useful.

Along with new features being added on the 17th of May all print requests from Digimap Roam and Geology Roam will have to be made using the print button  Print Button at the top right of the map. We will be removing the print tab from the list on the left of the map on June the 21st, but until then it will carry instructions on where to find the print button.

Print Tab

We are removing the tab to make room for the new features we are planning to add into the list on the left in the future.  You may have noticed that it is already getting a little crowded in Geology Roam, with Geology Photos and an Overview Map being added since the service was launched, and there are more additions on the way.

EDINA has been busy over these last few months creating some significant new features for Digimap Roam. To go along with the measurement tools we added at the beginning of April we are now working on some annotation tools.

Annotations ToolbarThese tools will allow you to draw symbols, lines and polygons on the map; add text, labels and area values; and set the colour and style of the features you have added. The features you add remain the same geographical size when zooming in and out and you can include them on your PDF print maps.

Annotations in use

Final version may differ from the image shown above.

You can download a sample PDF map here: Sample Annotations

We hope to have the annotation tools added soon, please keep checking the blog or the Digimap Facebook page for further announcements.
