Rebuild ready: 3D mapping a quake-damaged Cathedral
Surveying a damaged building can be dangerous. Mapping using drones reduces risk to staff and costs to the community.
In February 2011 New Zealand’s second-most populous city was rocked by an earthquake.
The iconic Christchurch Cathedral was shattered in the shake, and the cleanup is still ongoing.
Before the Cathedral can be rebuilt and the “red zone” surrounding it rejuvenated, a full survey is required. Christchurch City Council’s surveyor Jed Clement, Licensed Cadastral Surveyor, stepped up to the task with the help of drones and Pix4Dmapper.
