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.

How to create models of towns with building heights

Today’s guest blog is from Cristina Savian at Autodesk. If you were at last week’s GEO Business 2014 event, you may have seen our Acting Director General, Neil Ackroyd give his keynote and feature the image below, an infraworks model of Shrewsbury which was created using our new building height dataset. Cristina created the model and tells us how.
