LEGO cartography

As a self-proclaimed outdoor enthusiast, it’s no surprise our guest blogger Dan Harris is a Forward Planning Manager at the Cairngorms National Park Authority. In his spare time, he used our data to create a 3D LEGO map and in doing so, enthused many Twitter users. Here, he tells us about the project…

LEGO is an extremely engaging medium that can generate great enthusiasm in almost any subject, whether the audience is young or old. There are hundreds of examples of its use to promote subjects such as history, philosophy, economics, science and more, so I wanted to bring it to the world of cartography and use it to inspire engagement with mapping, landscape and place.

I’ve always really liked the way 3D relief maps can quickly and often dramatically convey the geography of an area. They’re popular and inspiring so to me, LEGO seemed like the ideal material from which to make my own; and where better to make one for than Scotland? With its mountains, islands and intricate coastline, it seemed to me to be the ideal subject. Plus, I live there and if it’s going to be displayed in my house, I want it to mean something to me.

One of my main objectives was to make the map using open data, so OS’s open datasets were an obvious solution. While I did consider other options, I decided that OS Terrain 50 DTM best suited my needs. To be fair, OS Terrain 50 is total excessive for a model of the resolution I had planned, but I wanted to use it so that in future I could create more detailed maps without having to process loads of new data. My map also includes a part of Northern Ireland, so I used the ALOS World 30m DSM to fill in that gap. Watercourses data came from the OS Open Zoomstack dataset, which is a great source of open data.
