Grid Vs. Ground Coordinates Explained for Trimble Access & TBC | Survey Matters

Join Mark White, Training and Support Manager at Duncan-Parnell, as he breaks down one of the most misunderstood topics in surveying: grid vs. ground coordinates. In this episode, Mark explains the difference between grid and ground coordinates, how scale factors affect your data, and why the sensor you're using doesn't determine whether you're working in grid or ground. He also demonstrates how to configure both Trimble Access and Trimble Business Center (TBC) for each workflow, helping you avoid common setup mistakes and work with confidence.
