Was Chester the intended capital of Roman Britain?
Inspired by a previous blog post that re-imagined Winchester as the nation’s capital through mapping, guest blogger John Murray applied this technique to Chester.
There has been much speculation amongst historians and archaeologists on whether Roman Chester (Deva) was intended to be the capital of Britannia.
This was the subject of a BBC Two Timewatch programme (Britain’s Lost Colosseum) from 2005 and, more recently, in Professor Alice Roberts’ Britain’s Most Historic Towns programme about Roman Chester.
During an archaeological dig in 1939, the remains of a substantial elliptical building were discovered immediately to the dextral rear (north west) of the headquarters building (Principia).
The map below shows the approximate location of these buildings. The elliptical building would have been approximately where the present-day Chester Market Hall is located.

OS Maps has a new 3D fly-through feature
Keswick Mountain Festival trail run.
Following the Easter indulgence, we’re releasing a new feature for OS Maps – the 3D fly-through. Perfect for planning GetOutside adventures with your friends and family or for justifying your chocolate consumption (just us?), you can visualise your whole route before you start your trip.
OS Maps feature in ITV’s Britain’s Favourite Walks next week
Tune into ITV at 7.30pm on Tuesday 30 January to see the nation’s favourite 100 walks revealed across England, Scotland, Wales and Northern Ireland*. Alongside National Trust and The Ramblers, we teamed up with ITV last year to encourage outdoors enthusiasts to vote for their favourite walks, and now the results are set to be revealed.

Over two and a half hours, presenters Julia Bradbury and Ore Oduba will showcase rambles, scrambles and ambles across the UK’s cities, countryside and coastline. We’re extremely pleased to say that four of our GetOutside champions will also be featuring in the programme, accompanying Julie and Ore on their walks. Look out for Two Blondes Walking in their favourite environment, Dartmoor; Zoe Homes (AKA Splodz) in Scotland; Phoebe Smith, wild camper and extreme sleeper; and the Get Out With the Kids family tackling the Chilterns.
Trodden paths with National Trust and OS Maps
By Richard Martin, GIS Analyst at the National Trust
As keen followers of the OS blog, we found the ‘trodden paths’ post in August of particular interest. The National Trust (NT) is a charity founded in 1895 by three people who saw the importance of our nation’s heritage and open spaces and wanted to preserve them for everyone to enjoy. We were therefore interested in discovering how much NT land currently occupies the most popular OS 1km map tiles that contain the largest number of public routes going through them. We were delighted to find that within the OS top 20 tiles (2,000ha) the NT looks after 924ha (46%), showing a very strong correlation with the places that OS Maps subscribers most like to walk.
Bringing augmented reality to OS Maps
We’ve just launched the new augmented reality (AR) layer in our OS Maps app which uses your phone’s camera view to display over 200,000 locations across Great Britain. You can identify hills, lakes, settlements, transport hubs and woodland around you and on the horizon. It’s the first time we’ve made AR widely available, but not the first time we’ve used AR. Our Computer Scientist, Layla Gordon, leads the team that experiments with geospatial data and new technologies to create proof of concepts that are shared with partners. Find out about Layla’s work on OS Maps, and the AR projects that came before it.
It’s fantastic to see the OS Maps app AR layer released and being used. You simply point the camera of your Android or iOS device at the landscape and, using GPS and the compass, accurate points of interest that sit in that view will be highlighted.
Taking a look behind the scenes, I created it using Apple iOS Core Location and Core Motion framework. The app accesses the readings from Gyroscope and Accelorometer, to give the accuracy we need. It calls on the OS Placenames API to retrieve the OS populated places, which delivers points of interest within a set radius based on position and orientation. We’ve then set rules within the app to identify which points of interest to prioritise – as the screen could get cluttered with too many points.
If you haven’t tried it yet, take a look at https://www.os.uk/getoutside/AR. But while this is the first AR experience I’ve created which made it to public release, I’ve been working on AR projects for a couple of years.
Augmented Reality in the great outdoors
By Tim Newman, Consumer Product Manager
For over a decade, OS has been active in the field of augmented reality – proving the concept back in 2006 with a thought-leading paper on Mobile Augmented Reality, and more recently prototyping 3D maps of Mars, and creating a navigation app for a Shoreditch basement. We’re now really excited to be using this augmented reality technology to introduce a new feature for OS Maps.
The recently released AR feature will help users learn about their surroundings by labelling and categorising the features around them, finally overcoming the big limitation of maps on mobile: the small screen. Have you ever looked out over a stunning vista and found yourself struggling to identify a hill or work out how far it was to the town below you? Now you can simply hold up your smartphone to find out what you’re looking at and how far away it is. If a place catches your interest, just tap on the label to find out more about it.
This fun and informative new feature was made possible by combining sensor data from the phone with OS data of over 200,000 hills, mountains, coastal features, lakes, settlements, transport hubs and areas of woodland. As a company of data experts, it’s fantastically rewarding to make use of our data to help make the outdoors more enjoyable, accessible and safe. This is what motivates the team and, combined with the great feedback we get from users, drives us to continue improving OS Maps – so keep your eyes peeled for the next bunch of features we’re working on to make it easier than ever to plan your time outdoors. There’s never been a better time to open up OS Maps and GetOutside!

Stay tuned to the blog to learn from Layla Gordon in the tech labs team about how it works and the exciting projects that she’s developing with augmented reality.
Snowdon tops the list for Britain’s most trodden paths
Did you know that OS Maps subscribers added over 400,000 routes to the service over the last 12 months? We’ve analysed the (almost) 400,000 public routes and found that Snowdon bags the top spot for most routes created.
We broke the country down into square kilometres and counted the number of routes passing through each square, and while Snowdon topped this list, the Edale area of the Peak District grabbed 6 of the top 10 spots, with the Lake District taking the remaining places.

Follow the Walk in the Park challenge on Friday

Northumberland National Park are celebrating their 60th anniversary this year and volunteer David Wilson is walking the entire length of the National Park, non-stop, later this week to celebrate. On Friday, David will be showcasing the varied landscape of Northumberland National Park throughout his 28-hour trek, following a route created with OS data and being tracked on an OS map embedded on the Park’s website.
David will be setting off from the north of the Park at 7am on Friday 27 May and is hoping to arrive at the Walltown site at the southern-most tip of the Park at 10am on 28 May on his non-stop trek. The final route was created with the help of National Park GIS Officer Ed Hudspeth, using the OS data he has access to. Covering almost 70 miles the route covers stunning areas of the Park, including Yeavering Bell, Newton Tors, Cheviot and Hadrian’s Wall. It also covers the practical areas and takes in places that allow David access to food, water and other supplies.
