The spectacular setting of Ben Nevis provides the backdrop for an Oculus Rift game created by Ordnance Survey developers, in which players race against the clock to find a hidden trig pillar.

The virtual worlds were created in OS Labs, the OS department designated to exploring and assessing ideas for new products and services.
John Abbott, who as Head of Access and Services is responsible for OS Labs, says: “As with the Minecraft maps of Great Britain, we thought the public would be interested in how our data can work in the virtual world, which is why we’ve shared these Oculus and cardboard experiments. My team continues the long OS tradition of constantly examining the data that’s available and its uses in emerging technologies. We do this to see how we can make our data offerings work better for the public, government, business and partners.”
Abbott continues: ”OS has no plans at present to create further virtual worlds, but what we have demonstrated is that it can be done, and in terms of future uses it is the perfect medium for visualisation. It can be used for planning, as a test environment for running scenarios. Put real-world data into the virtual world and you gain a level of experience and understanding of an environment that can only be bettered by actually being there.”
Both the Oculus and cardboard versions of Ben Nevis took just two days to create. For the developers Alex Davies-Moore, an early pioneer of the uses and capabilities of iBeacon technology for geospatial Internet of Things solutions, and David Haynes, a specialist in 3D mapping and virtual reality, these virtual Ben Nevis environments have been an opportunity to bring their external interests into the workplace.
David says: “I’ve been looking into VR for a while now. There’s a natural crossover with my work in 3D mapping. I’ve no doubt the cardboard and especially the Oculus will quickly establish themselves as important in how we consume entertainment. The potential is obvious and massive. Gaming, film, sporting fixtures, gigs and events will be so much more immersive and better - the next best thing to actually being there. There is also a leisure market to consider. These technologies act as a passport for people who want to experience the sights and sounds of places they can’t get to, and as a planning tool for people preparing to visit these places.”
The inclusion of OS’s accurate data gives the virtual world an added sense of reality, and it was the adding in of the data that presented the greatest challenge, as Alex explains: “We used Unity 3D, a well-known and easy-to-use gaming engine, and it took us a while to figure out how to get it to work with and display the data as realistically as possible. The more we play with this technology and experiment with putting real world data into it, the more realistic these worlds will become, and so the number of commercial end uses increases.”
