Glastonbury LiDAR Data – A Little Something Extra

Every year we proudly take to the skies to capture the world famous Glastonbury Music Festival at the site in Worthy Farm, Somerset. As part of our agreement with Glastonbury, we provide the organisers with a high-resolution aerial photography for the entire festival area.

The high quality data supplied is used for a whole host of purposes, ranging from site planning, crowd safety, to accommodation facilities, and provides Glastonbury Festival with the intelligence to plan a safe event for music goers to enjoy.

But what else could Blom provide to accompany the traditional aerial imagery? What other aerial information could be supplied that would contribute even more site information to Glastonbury Festival? – LiDAR was the answer.

While aerial photography gives an incredibly clear and unobstructed view of what’s on the ground, it doesn’t provide information about the ground itself. Utilising the LiDAR data, we produced a highly detailed Digital Terrain Model (DTM) of the entire site, which provides accurate data of the elevations. The DTM effectively creates a ‘3D’ model of the terrain, which you can’t fully appreciate with aerial photography but compliments it perfectly.

LiDAR (Light Detection and Ranging) was provided in addition to the aerial photography.

Having access to the DTM proved a useful tool to Glastonbury Festival for a wide range of uses, but a couple that stood out were;

  • Line of sight and sound – Planning where the stages go is a big part of the event. Being able to calculate the audio impact and levels of noise on and off site it vital, so having a visual plan of the ground that could be viewed quickly from an office, improved decision making.
  • Slope analysis – Understanding where the slopes and flat areas are, is ideal for the planning of camping sites and positions of structures. Simple calculations can be performed to determine accommodation capacities of ideal camping locations, as well as determining the best positions for stages and structural installations and providing information for more accurate drawings.

Looking to the future, a full 3D drawing of the site could easily be produced, incorporating the LiDAR data with aerial photography, creating a fully textured model that can be viewed and manipulated, as well as even 3D-printed – we are sure a miniature scale model of the site, complete with tents would make a brilliant memento!

As the festival grows and changes over the coming years, Blom will be certain to adapt and change to suit Glastonbury Festivals requirements, whatever they may be.
