Exploring our surveying antiques

The prospect of the upcoming move to our new head office has resulted in buzz of increased activity around the building in recent months. Just like when you move house, it’s been a good time to have a bit of a clear out and take stock of what’s been hiding under the proverbial bed or in the attic.

Well, part of that process has included cataloguing the many pieces of antique surveying equipment that have been accrued by Ordnance Survey over the past 200 years. Some of the items have played an historic role in the birth of modern map making in Britain and are irreplaceable.

To understand more about some of this fascinating equipment, I caught up with Ken Lacey, a surveyor by trade who now works in our education team. Ken was kind enough to give me a tour of what is rapidly turning into an Aladdin’s cave of cartographic memorabilia, with two pieces being of particular interest. Read More

Tryfan stands tall(er)

Last week I wrote about an expedition to resurvey the height of Tryfan using modern GPS technology – the same technology the Ordnance Survey uses to map the country. Well, it was a great success and here is an account from John, Graham and Myrddyn. You can also watch an interview with our very own Mark Greaves on the BBC website.

The morning began dark and grey as we drove into the car park at Ogwen cottage, dark because it was just after 5am and grey because a fine drizzle had fallen on the valley.

Visiting the Director General’s House

Vanessa Lawrence, our Director General recently paid a visit to a particularly special building in Southampton. 15 Rockstone Place is near the centre of the city and is now the home of a solicitors firm, but it for many years it had a very close association with Ordnance Survey as the ‘Director General’s House’.

The house was built in 1840, and was one of the last projects of Samuel Toomer, who died in 1842 at the age of only 41. It was originally called Avenue House and for the next 25 years it served as a private residence. Read More

Surveying one of Snowdonia’s highest mountains

Over the past year or so, I’ve been working with a group people who are on a quest to rewrite the map of Great Britain.

John Barnard, Graham Jackson and Myrddyn Phillips have been tirelessly climbing some of the country’s most famous peaks and measuring their heights using state-of-the-art GPS equipment.  In doing so they have helped create mountains where once there were mere hills, and vice versa of course!

Their latest expedition takes them to Snowdonia and one of Wales’ most iconic mountains. Read More

Here’s the second in our two part series on the history of the OS Explorer map. Read part 1.

The 1:25 000 scale Ordnance Survey map evolves

Pathfinder maps proved very popular with walkers and other leisure users but after a while steps were taken to make the map even more user friendly. The first experimental Explorer maps were published in 1994, with five maps issued simultaneously covering parts of the Chilterns, Mendips and Northumberland. On average the new Ordnance Survey maps covered three times the area of their predecessor Pathfinders, and were six times bigger than the blue-covered originals (originally Outdoor Leisure maps) at this scale.

Bronze Age farm discovered at OS head office

I met up with Wessex Archaeology recently to find out about the previous residents at Adanac Park, the site of our new head office.

Back in 2008, as part of the planning process, Wessex Archaeology were asked to investigate the site for historical interest. They were fairly confident of finding some archaeological remains as there had been finds at sites in the local area, but were surprised to find evidence of a late Bronze Age farm, the first of its kind in this part of Hampshire.

Archaeologist Andrew Fitzpatrick told me, ‘The site proved to be late Bronze Age, around 3,000 years old, four or five houses and evidence of smaller structures, such as storage sheds and granaries. There was also an Iron Age burial ground with seven barrows and other graves. This was quite unexpected and the site is unique in Britain.’ Read More

The history of the OS Explorer Map

Here’s the first in our two part series on the history of the OS Explorer map.

OS Explorer Maps – the beginning

The iconic OS Explorer Map, used daily by thousands of people from ramblers to rock climbers and named by the Design Council as an official millennium product, has a fascinating history. Did you know, for example, that it wasn’t until 2005 that the whole of Great Britain was covered, including remote areas of the Scottish Highlands?

Using OS OpenData to fight fraud

We are really excited that CIFAS – The UK’s Fraud Prevention Service, a not for profit organisation, has been using OS OpenData to help them recruit local authorities into membership.

Simon Fitzgerald, CIFAS Programme & New Developments Manager, was very enthusiastic about the release of OS OpenData, and downloaded OS Street View, Boundary Line and Code Point Open for the London Boroughs as soon as the service went live. Using a freely available open source Geographic Information System, Simon set about loading elements of the fraud data that CIFAS collects from its Member organisations spread across the financial services sector and beyond.
