The Boundary Line Cold Case: Surveying an Australian Wasteland.

In this video, I’m investigating a 140-year-old boundary mystery hidden in a site overgrown with trash and bush. Using modern land surveying technology like the Leica GS18T, I have to reconcile 1880s survey plans with the reality on the ground today. Whether you are a professional surveyor, a student learning how to find property markers, or just someone who loves a "cold case" history hunt, this video walks you through the entire technical process. We use GNSS technology and historical archive data to find markers that have been "lost" for over a century. In this video, you’ll see: The hunt for original 1880s survey pegs and ancient boundary markers. A deep dive into boundary survey techniques using Leica Captivate. Technical Workflow: I demonstrate the resection method in surveying applied to GNSS as a localization using the create coordinate system app. How we bridge the gap between historical plans and modern independent coordinates in a survey. The challenging reality of surveying on overgrown sites, dealing with omitted measurements, and reconciling old data. This is a real-world look at how land surveying works when the history is buried and the stakes are high.
