Can you help colour London’s buildings?

Created by The Bartlett Centre for Advanced Spatial Analysis at University College London, Colouring London is a free online platform set up to crowdsource information and share expertise on London’s buildings to make the city more sustainable. We’ve supported this project from day one and are delighted to be part of it. 


Using OS data for the building outlines, this project is designed to collect, collate and visualise around 50 types of statistical data for every building in London. These are grouped into 12 core categories: location, land use, building type, community assets, age and history, size and shape, construction, team, sustainability, street context and environment, planning and protection and like me?.

London’s most popular walks this year revealed by OS Map users

Thousands of subscribers to OS Maps have been out in force wandering the streets of London over the summer months – providing some revealing insights for us here at OS.

So many of you have poured out of tube stations, alighted from buses and spilled out of car parks to get outside and enjoy the majesty, wonder and gorgeous green space of London.

Thousands of journeys have been unselfishly logged, recorded and shared as routes in the phone and web app, whether that be cycle routes, gentle strolls or epic walks. And the data has thrown up some interesting results.

The number one place to start a walk in London this year – and end it – was Richmond station.

Active Travel Hackathon

Here at OS, we encourage and promote the benefits of being active – in fact, it’s even one of our company values. We are often involved in projects and campaigns to inspire more active lifestyles and, with support from our Geovation team, next week’s Active Travel Hackathon in London is no different.

Over the past ten years Geovation, our open innovation initiative, has hosted a handful of themed challenges aimed to encourage more active means of travel. With our involvement in next week’s hackathon, we are delighted to be able to continue these efforts on a larger scale. Read More


What happened when Team OS took on the 56km London 2 Brighton Challenge?

Team OSToday’s guest blog comes from ‘Team OS’ – Tara Anglim, Rick Hunt and Andy Carlisle, who walked the 56km London 2 Brighton Challenge on Saturday 24 May to raise money for Alzheimer’s Society.

Over the Bank Holiday weekend, we joined 3,000 others in tackling the London 2 Brighton Challenge. We’d heard that it would be gruelling, but we fancied a challenge and a chance to try out our new Event maps. After leaving home at 5am to get to the start point in Richmond, we set off on our 56km challenge at 8am.

The first 10km or so was lovely. We walked beside the Thames and enjoyed the scenery, including canal boats, canoeists, and houses on the waterfront. It was so lively that the time flew by.

A day in the life of a surveyor in London

We’re often asked about the work Ordnance Survey does, and unsurprisingly the role of surveyor crops up most often. I asked Tristan Shearing, one of our London surveying team, to give us an insight into his role…

Tristan at work in LondonWhen I tell people I work for  Ordnance Survey as a surveyor, the most common response is ‘But isn’t everything already mapped?’. Confusion truly sets in when I tell them I work in an area of North London, far from the mountains and moorland they associate with Ordnance Survey mapping. When I explain that every time a house is demolished and rebuilt, or an estate is regenerated, or a prestigious new tower block is constructed, the London surveyors are on the scene taking measurements and updating the large-scale mapping, it starts to make a little more sense.

New exhibition at the Tower of London

Although we’ve spent the last 170 years based in Southampton, Ordnance Survey’s early days were actually at the Tower of London. This early period of our history is being celebrated with the new Power House exhibition in the Tower.

The exhibition gives visitors the chance to discover the stories and personalities behind the major organisations of state, who took care of Royal business behind the mighty Tower walls, from 1100 to the present day.

It showcases the roles of the major organisations that provided the bedrock of England’s power throughout the centuries – including the Ordnance Office, Ordnance Survey, the Royal Mint, Record Office, the Jewel House, Menagerie and Royal Observatory. Power House also puts the spotlight on other Tower of London functions, ranging from royal residence to state prison.

An amazing three metre high ‘bejewelled’ dragon greets visitors to the exhibition in the White Tower. The dragon is made up from parts representing the organisations in the exhibitions – our mapping forms part of the wings.

The Ordnance Survey section of Power House gives our early history. The Board of Ordnance became residents of the Tower in 1716 when a Drawing Room in the White Tower was fitted out to allow for mapping to be drawn. In 1791 Ordnance Survey became a distinct branch of the Board of Ordnance and began to map England and Wales. We remained resident at the Tower until a fire in 1841. We then became a government department in our own right and moved to Southampton, where we remain today.

Also on display is a copy of the first map produced by us. The map of Kent was completed in 1801 at the Tower of London Drawing Room. Produced at the one inch to one mile scale, it was printed by William Faden of Charing Cross, a leading cartographer and map publisher at the time.

There are some fascinating stories to be told by the other residents of the Tower too. Including the tale of William Foxley, potmaker for the Royal Mint, who fell asleep for 14 days and 15 nights. The poor soul was viewed as a curiosity and was prodded, poked and even burned in an effort to rouse him. Even King Henry VIII visited the Tower, to witness the ‘spectacle’ for himself.

Mapping the Olympic Park

The Olympic Park

The Olympic Park

We received some very positive feedback following Liz’s blog post a few weeks ago about our Engineering the Olympic Park map.

The Institution of Civil Engineers was inundated with requests for copies!

The original print run has now been distributed to ICE members and to education groups visiting the Olympic site.

So, as we’re not able to send out any more copies, we thought it would be a great idea to make it available to download (pdf).

Hopefully it will give you a taster of the development that has taken place on the site since 2001 and the contribution that Civil Engineers have made.
