On a construction site, sub-centimeter accuracy in surveys mean the difference between a successful project and a multi-million dollar mistake. Contractors rely on accurate surveys to pour cement for structural posts, check progress against design plans, and collaborate with teams of subcontractors on a job site.

DJI released the Phantom 4 RTK in October 2018. The out-of-the-box onboard RTK capabilities provide massive time and cost savings for construction companies throughout the project lifecycle.

To compare the accuracy of the new DJI Phantom 4 RTK (P4R) versus traditional drone data, Katerra—a Technology-driven offsite construction company—conducted a comparative analysis survey on an active construction project in Hayward, California using the P4R and DroneDeploy to process the data.
