While we’ve already celebrated the 25-year landmark since the last traditionally-cut benchmark was carved, we thought we’d carry on the merriment by adding them to OS Maps!
Yes, you heard right. So if you’re an avid benchmark bagger or just intrigued by geographical history, you’ll be delighted to know that, instead of downloading our benchmark archive, you can simply find them on OS Maps desktop. Not only that, but when you click on the specific benchmark, it will tell you which one it is and when it dates back to!
What is a benchmark?
While 2018 marks the 227th anniversary of Ordnance Survey, lest we forget it is also the 82nd anniversary of the first observations from our ‘hotine’ trig pillar!
If you want to find out who created our well-known trig pillars and the memorial we have for him at our head office, you’re in the right place.
Brigadier Martin Hotine CMG CBE RE was born on 17 June 1898, in Wandsworth, London. He read mathematics at Magdalene College and was then commissioned into the Royal Engineers (RE). Hotine was in the RE for many years and served in both the First and Second World Wars.
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.
The Lakes Ignite programme for 2018 features an OS-inspired work of art called Ordnance Pavilion, paying homage to the trig pillar and the work of OS surveyors in mapping Great Britain. It’s flattering to be an artist’s muse, but we wonder if it’s not the first time OS has inspired an artwork…
Created by Studio MUTT, Ordnance Pavilion is an interactive installation in the Langdale Estate in the Lake District. It forms part of Lakes Ignite 2018 which presents six contemporary artworks to celebrate the Lake District’s designation as a World Heritage site. On display between until July 2018, Ordnance Pavilion is a celebration of OS and how our maps have impacted people’s interaction with the landscape.
The Timepix historic photo site launches today and makes a unique set of photos from OS’ history available online for the first time. Over 21,000 photos catalogue the Manchester streets between the 1940s and 1960s, giving a unique insight into the city’s past captured by OS surveyors. From children and animals photobombing the surveyors, to a background of vintage adverts, Timepix showcases a fascinating collection of photos around Greater Manchester.
Why were OS surveyors photographing Manchester?
OS surveyors took revision point (RP) photos across Britain to provide a network of surveyed locations. These known spots could then be used to ‘control’ the position of detail on a large scale map. RPs were often on corners of buildings and other immovable features, and were fixed to centimetre accuracy. Finding the RPs for future map updates was an issue, and photography quickly became the best visual reference – leading to thousands of photos of men with white arrows…
If you were watching Antiques Road Trip yesterday afternoon, you’d have seen antiques expert Paul Laidlaw visiting our Southampton head office. The modern building we’ve been in since 2009, is a far cry from our first home at the Tower of London, and even the military barracks which became our first Southampton head office. But, despite being a digital data company in a state of the art building, there are still many nods to our mappy heritage to be found.
Our CEO Nigel Clifford showed Paul our first map, and an early theodolite while filming for the programme. Here’s a bit more about them:
We’re heading to London on Friday to take part in a celebration of all things map, geo and cartographic at the British Library’s evening bash. But did you know that London used to be home to Ordnance Survey? Although we’ve spent the last 176 years with our head office based in Southampton, our early days were actually at the Tower of London.
This year marks the 225th anniversary of OS, giving us a map-making history to be proud of. Over the years we’ve amassed quite a collection of artifacts, many of which are dotted around our Southampton head office – including a Ramsden theodolite in our CEO’s office and a copy of the 1801 map of Kent in our Business Centre. Watching the current ITV adaptation of Victoria, we were reminded of another stunning historic item, the Jubilee Book.
Compiled in 1887 to celebrate Queen Victoria’s Golden Jubilee, the book showcased the changes and innovations that had taken place at OS during the Queen’s reign. Director General Sir Charles Wilson presented the original volume to Queen Victoria at Osborne House on the Isle of Wight in 1887. Two further copies were made, one retained with OS in Southampton and the other going to Ordnance Survey Ireland. When our head office was attacked in the Southampton Blitz, our copy was sadly destroyed. However, to mark the opening of our (then) new head office at Maybush, Ordnance Survey Ireland gifted us their copy, which we keep safe to this day.
Did you watch the great Timeshift on BBC4 last night about OS? A Very British Map: The Ordnance Survey Story told the tale of how we’ve mapped every square mile of Britain for the last 224 years. It covered our military origins through to how our leisure maps have helped people discover and explore the countryside and beyond.
As mentioned towards the end of the programme, while we may be best known for our paper maps, they now account for just 5% of our business. Our location data has woven itself into the fabric of our everyday lives across Great Britain. We produce digital map data, online route planning and sharing services and mobile apps, plus many other location-based products so you know exactly where you are.
