If you loved our data visualisation showing Great Britain’s largest islands – great news, it’s now available to buy. In case you missed it at the time, our GeoDataViz team worked with Alasdair Rae at the University of Sheffield to explore Britain’s largest islands. They found that there are 82 English, Scottish and Welsh islands larger than 5km2 and created this beautiful poster to showcase their work.
We were overwhelmed with the fantastic response to the poster and inundated with hundreds of questions, many asking about missing islands. As we were only looking at Great Britain’s islands, this didn’t include Northern Ireland’s islands, the Isle of Man or the Channel Islands. You can see more about the difference between Great Britain, the United Kingdom and our Crown Dependencies in this blog. There are many more islands around Great Britain smaller than 5km2 – they’re just not included on the poster.
We also had a lot of requests for a printed poster, and our friends at the University of Sheffield have made this happen. There are a limited number of posters available, at A1 size which you can buy on their website for £15.
Continuing our series to introduce some friendly faces from the people working at OS and showcase the wide variety of work we do, meet Joe Harrison. Joe joined OS on our graduate scheme in 2017 as a data scientist and has worked in a few areas of the business so far. If you’re a follower of the blog, you may recognise some of the project Joe’s worked on…
Hi, I’m Joe, one of the data science grads from the most recent graduate scheme. My first placement was an eight-month stay in the Consultancy & Technical Services team from September until the end of March. I then moved to the GeoDataViz team with Charley and Paul for a two-month placement.
Scottish Boundary Commission
During my first week in the team, Charley was contacted by the Scottish Boundary Commission who wanted advice on how to visualise the new Scottish constituency boundaries and the changes. I created a couple of examples using QGIS. I improved the clarity of the maps by reducing the number of colours, and by adding shadows to emphasise areas of interest.
With the English football season about to kick-off for 2018-19, our GeoDataViz team have been visualising the 92 football league grounds in one huge poster. The Premier League, The Championship, League One and League Two grounds have all been mapped using OS OpenData and put in order by stadium capacity.
Did you know, we show over 220,000 km of public rights of way on our maps? Approximately 170,000 km of these are footpaths and 40,000 km are bridleways. Over 4,600 km are National Trails and 30,900 km are recreational routes!
One thing we’re often asked about is when someone has followed a public right of way shown on our map and found no visible footpath on the ground. Why is this? Public rights of way information is sent to us by local authorities, and a right of way doesn’t necessarily mean a footpath on the ground. We’re also often asked about blocked or overgrown rights of way. These need to be reported to your local authority too and, if any changes on our maps are required, they will pass that information along.
We also map rights of way permissive footpaths and bridleways as well as byways. And, if you don’t know the key differences or symbols of each of the types, you’re in the right place to find out!
Great Britain is an island in its own right, but aside from the mainland, there are hundreds of islands around the British coast, many uninhabited*. Inspired by David Garcia’s data visualisation of the Philippines, our GeoDataViz team worked with Alasdair Rae at the University of Sheffield to explore Britain’s largest islands.
They found that there are 82 English, Scottish and Welsh islands larger than 5km2. Scotland boasts the vast majority with 71, not surprising when you consider the Outer Hebrides, Shetland and Orkney and other beautiful islands off the coast. Wales had just 2 entries and England 9.
Guest blog by Sophie Kirkpatrick, Founder of Atlas & I.Have you ever met anyone who doesn’t love an antique map? Their unique charm and history is endlessly relatable and you can never tire of exploring an old map of a sentimental location. To study old maps in antiquarian book shops and libraries is one undertaking, but to own an original antique map is a luxury reserved for the wealthy or bequeathed.
Cartography or map making has been an integral part of human history for thousands of years. The earliest maps are recorded as far back as the 24th century BC, depicting simplistic line drawings of hills, rivers and cities on a clay tablet.
Citing his inspiration as our post that reimagined Winchester as the nation’s capital, we recently published a guest blog by John Murray. Following the episode of Channel 4’s Britain’s Most Historic Towns, John replicated our technique to reimagine Chester (Britain’s most Roman town) as the capital.
Out of curiosity, we thought it could be interesting to see what other cities would look like if they were the capital. As with Winchester, many cities have backstories which historically make them viable capital candidates. We got our Graduate Consultant Data Scientist, Jacob Rainbow, involved and, as with the Winchester map, he applied the same process.
Guest blog by Ewan Campbell, composer of Glynde.
In many ways cartography is to a landscape, what music notation is to sound. They both use two-dimensional visualisations to represent something which is multi-dimensional, and in the process create a beautiful pictorial format of their own. My map enthusiasm is driven by a desire for the overview that a maps offers, and the scope to explore the virtual depiction of a landscape.
There is however a crucial difference between the two idioms: music is always experienced through the temporal dimension, and time, as we know it, can only ever run forwards. No matter how many repeats, verses, loops or recapitulations a composer may decide to add there is always a beginning which at some moment later must be followed by an ending. As a result traditional music notation is linear, and read forwards like a book. The aim of my cartographic music is to make the musical form visible. The 2-dimensional score offers a structural overview of the virtual musical soundscape, which can be imaginatively entered into, just as one would ‘read’ a topographical map.
You may know about our trig pillars, but did you know that there are more nostalgic reminders of how we used to map Great Britain?
Have you ever seen one of these while you’ve been out and about? If so, it is highly likely you have spotted one of our renowned benchmarks. 2018 marks 25 years since the last traditionally-cut arrow style benchmark was carved on a milestone located outside The Fountain pub in Loughton.
Early in 2018 Ordnance Survey (OS) were approached by the Registers of Scotland (RoS) to support their Data Month, an internal event for RoS staff held in March to facilitate the sharing of knowledge and best practice across the business. RoS is the non-ministerial government department responsible for compiling and maintaining 18 public registers. These relate to land, property, and other legal documents and include the Land Register of Scotland and General Register of Sasines.
