Characteristic Britain’s Ordnance Survey (OS), based in 1791, is interloping within the digital age. Minecraft, AR gaming, and EV charger locations have all turn out to be a part of its portfolio, alongside the paper-based maps beloved by the nation’s legion of cagoule-clad out of doors sorts.
However the digital mission goes deeper, CTO Manish Jethwa tells The Register, pointing to roof sorts for example.
“OS has secretly, behind the scenes, been engaged on it. It is an embedded a part of our manufacturing pipeline. The datasets that we produce as we speak are already using machine studying, together with understanding roof sorts and roof supplies routinely from aerial imagery. We use machine imaginative and prescient to get 3D fashions of the roofs and perceive facet and space. When you may then take these two datasets collectively, you can begin to in a short time perceive areas for photo voltaic potential of buildings, we will additionally detect the place buildings have already got photo voltaic panels,” he says.
OS has been placing collectively its buildings dataset over 5 years. In September 2024, its basement presence was launched and in March this 12 months OS launched a set of roof information to supply info on 28 key attributes for greater than 41 million buildings throughout the UK.
The info is utilized by banks and insurers to supply extremely correct details about the constructed atmosphere which they will belief when making danger and lending selections, figuring out fraud or making sustainability assessments.

OS developed the Unique Property Reference Number (UPRN), which may be built-in with different third-party datasets corresponding to flood-risk information which monetary companies establishments must make important selections. The UPRN gives the definitive hyperlink at a constructing degree which is way extra correct than utilizing postcode information.
Now a publicly owned restricted firm, the nation’s cartographer was based within the wake of Scotland’s Jacobite riot of 1745 and gained backing in the course of the Napoleonic wars. It first launched an digital OS MasterMap database again in 2001, containing greater than 600 million geographic options.
Earlier this 12 months, OS started a seek for a tech provider to assist it receive and handle information from utility firms for a mission that goals to keep away from injury to subterranean infrastructure, which prices round £2.4 billion a 12 months. Now in its beta part, the National Underground Asset Register (NUAR) gives a digital map of underground pipes and cables in England, Wales, and Northern Eire. The federal government mentioned the mission would assist completely different teams that set up, keep, function, and restore buried infrastructure.
Constructed during the last 20 years, the information stack is various, Jethwa says. “From a legacy perspective, our databases are constructed on conventional structure, utilizing PostgreSQL to develop capabilities in-house.”
By way of information administration at scale, OS predominantly depends on Microsoft Azure’s information stack internally, but in addition works with distributors corresponding to Databricks to run spatial queries on large-scale datasets and create catalogs.
However the measurement of the datasets OS is ready to exploit is usually a burden in addition to an asset, Jethwa explains. “They’ll persist for a minimum of a decade, if no more, and so the methodologies that we develop usually should be enduring capabilities. It is a problem for us,” he says.
He explains that large-scale enterprise transformation initiatives to develop new companies cannot deal with the entire information lifecycle, due to the longevity of the datasets. OS is transferring from a “mission administration or program administration perspective way more onto like a product-led [one], the thought of making enduring groups, each on the platforms that we construct and when it comes to the companies that we provide, implies that we will repeatedly iterate slightly than occupied with them as remoted initiatives,” he says.
Whereas it has deep roots in machine studying, OS can be adopting the newest pattern in genAI and enormous language fashions. Internally the group is exploring how they might help open up datasets to non-expert customers, Jethwa says.
“Constructing spatial queries goes into the reserves of geographic info system (GIS) specialists. If you wish to all the buildings which might be inside 100 meters of a water characteristic, as a result of perhaps you are attempting to establish buildings that is perhaps prone to flooding, you now must construct very particular queries, that are buffering the prevailing options by 100 meters after which taking buildings that exist inside that buffer zone.
“These type of spatial information queries may be fairly onerous to have the ability to create by hand. However massive language fashions show you how to to have the ability to translate a pure language expression, by an API request, to have the ability to truly pull that information out. It opens up the realm to a website knowledgeable, however not essentially a GIS knowledgeable,” he says.
OS has to steadiness its mission to supply usable geographic info to companies and different organizations with its responsibility to the general public. “Along with type of offering these, these datasets out to the markets, we’re simply attempting to get extra individuals outdoors,” Jethwa says.
In 2021, OS partnered with recreation developer PRELOADED to construct an AR recreation to encourage individuals to get outdoors and discover the UK.
“Persons are adopting new methods to have the ability to work together with our information. They need to have the ability to discover and share route info with each other. That is primarily the ‘get outdoors’ group facet of what we do, whether or not it’s by video games or now by the OS maps app,” Jethwa says.
The sources of knowledge upon which OS can construct is ever increasing. It could possibly extract options instantly from drone and aerial imagery through the use of deep studying algorithms and supply it in an ever extra up-to-date style.
Nevertheless it isn’t nearly accuracy. Jethwa says OS needs to make the information match for goal so it may be adopted in additional locations. “We wish to hit extra locations within the sense that we wish to get our information into extra fingers. We all know already that our information is touched by the typical consumer 42 instances on daily basis. However even that does not really feel prefer it’s sufficient.” ®
