Case Study: Eliot Sinclair and Partners achieves accurate LiDAR verification after the Christchurch earthquake with 12d Solutions

LiDAR Verification post Christchurch earthquake (2011) - Eliot Sinclair and Partners

Eliot Sinclair and Partners, a civil engineering firm, faced a significant challenge following the 2010-2011 Christchurch earthquakes. The client needed to verify the accuracy of massive post-earthquake LiDAR survey datasets for SCIRT, but inherent errors and a drastic reduction in usable control marks (from 3500 to just 30) made the analysis extremely difficult. They required a powerful solution to process and compare billions of data points effectively.

12d Solutions provided the necessary tools and support. Eliot Sinclair and Partners utilized 12d Model's surveying and TIN reporting functions, developing custom macros to analyze the LiDAR data against the remaining control points. The solution allowed them to present clear, color-coded variance reports. The results were so robust that they were successfully peer-reviewed and independently verified, confirming 12d Model as the right software choice and impressing the client with the firm's responsive and accurate analysis.
