Creating 3D data for Countryfile

If you tuned in to BBC’s Countryfile on Sunday, you’ll have seen Roger Nock from our Flying Unit talking to Adam Henson at his Cotswold farm. We were talking about how the aerial imagery we fly in our planes has been used to map hedgerows for the Rural Payments Agency, and help work out subsidies for farmers. We showed an example of how 3D data can be captured and displayed over Adam’s farm.

After the programme, we received a tweet asking where the LiDAR camera was in our plane. The answer is simply that we don’t fly LiDAR (3D laser scanning of the ground) and our planes are surveying aerial imagery (taking a photo with a high-resolution camera on-board the plane). We are treating this imagery in a similar way to how others would work with LiDAR data though.

3D streaming

At last, serving huge quantities of 3D geospatial data into interactive user applications is getting easier and more accessible. Support for ‘3D streaming’ is gaining a foothold within popular geospatial applications, paving the way for data providers to present their own 3D data assets in ways that users will find natural and accessible. For us at OS, this is a development that we’re very excited about, as we believe it will be a powerful tool in helping to unlock the potential of geospatial 3D data.

For many people, Google Earth (launched in 2005) was their first experience of navigating a ‘digital globe’ – a tool that is typically supported by ‘streaming’ technology. Overwhelming volumes of geospatial information were clearly available, yet how had it got there? Although Google Earth was then only available as a downloadable app, it was clear that the data was being sourced quite independently. For many of us, this served as our introduction to ‘3D streaming’ – the ability to selectively deliver content, based upon real-time navigation, within a 3D scene. Read More

See a 3D map of London at The Building Centre

We blogged about the fab 3D map of London on display at MIPIM back in March. Now, the New London Architecture (NLA) team’s huge model map has come back home to London and you can go and see it. The New London Model was built by Pipers, with data supplied by us at OS, using a combination of laser-cutting, 3-D printing and hand-crafting.

The New London Model is 12.5 metres long

Unveiled today – London like you’ve never seen it before – thanks to an OS treasure trove

Guest blog by David Roberts, Ordnance Survey’s Land and Property Strategic Relationship Manager 

The tens of thousands of pieces of geographical data and knowledge about London, which OS capture every year, have been brought to life in a unique way. The largest ever model of London, commissioned by New London Architecture and sponsored by OS, has been unveiled today on the London Stand at MIPIM, the annual get together of the most influential international property players in the world in the most elegant of French locations – Cannes.

21st Century twist on a Victorian geographical melodrama

Gary PDr Gary Priestnall, at Nottingham University’s School of Geography, is aiming to recapture the sense of wonder which an extraordinary 15-foot by 14 foot, 3D, sculpted model of the Lake District inspired when it was unveiled in Keswick in the 1870’s. It has spawned a new exhibition opening at Keswick Museum and Art Gallery on Monday February 9 which runs until May. It’s part historical detective story, and part 21st Century, technological success story and Ordnance Survey has helped Gary every step of the way. Here is his story. 

A unique 3-D model of the Lake District which would have offered Victorian tourists their first bird’s eye view of the Lake District has been known about since it caused such a stir in 1875. So when the one last surviving, beautifully hand-painted piece of the model, as well as 140 of the original plaster moulds used to create it, fell in to my hands the chance to celebrate the event in 2015 with an exhibition became my cause celebre.

Using machine learning to build the future of 3D mapping

IS-3

Earlier this year we made the alpha release of our building height attributes available to our existing OS MasterMap Topography Layer customers. Almost 20 million building heights across Great Britain were released as an early step in our migration to enhanced 3D geometry and we’ve been gathering feedback ever since.

One of the most common themes being fed into our OS Insight programme has been around the shapes of roofs, as this can help our customers make planning decisions, create realistic views and model sunlight and telephone signals around buildings. Our Research team have started to look into this for the future development of our product.

Currently, our building heights define the bottom of the building, and the top and bottom of the roof. Isabel Sargent and David Holland in our Research team have been working on a small project to see whether it’s possible to automatically extract the shape class of each roof and whether buildings that don’t fit simple height data can be identified.

Semantic and Geometric Enrichment of 3D Building Models

Today’s guest blogger is Jon Slade. Jon’s currently working on his PhD at Cardiff University, sponsored by Ordnance Survey.

After a fruitful year spent as a GIS Specialist at Arup I chose to change direction and return to the world of academia to study a PhD full-time at Cardiff University. Whilst I found the commercial world, in which I have worked for 15 years rewarding I missed really immersing myself deeply in a topic. My UCL MSc Summer research project ‘Google Maps Journey Immersion’ gave me a taster of this. And so, with experience of civil engineering from my time at Arup, a life-long love of maps and all things Ordnance Survey plus an unashamed fondness for reality architecture shows such as Channel 4′s Grand Designs, the opportunity to study a PhD on the Semantic and Geometric Enrichment of 3D Building Models at Cardiff, sponsored by Ordnance Survey felt ideal. This shall be my main area of work for the next 3-4 years.
