Increase Total Station Vertical Accuracy (The Common Point Method)

Can a Total Station Rival a Digital Level? Discover the Common Point Method for precise elevation transfer in traverses. ​ This video explains trigonometric levelling basics, error sources (HI/HT, atmospheric, compensator), and a field-tested technique using common points like ball prisms to eliminate vertical errors achieving sub-mm closures over 1.5 km in STAR*NET. ​ What You'll Learn: Traverse vertical control fundamentals and error propagation. Field setup: Measure common points between legs for bracing. Post-processing: Ignore HI/HT in least squares adjustment. Real results: 0.4 mm misclosure vs. 2.4 mm traditional; raw data download available. Faster than 2D traverse + differential leveling. Inspired by Jesse Kozlowski's trig levelling paper. ​ Raw Data Download Link : https://1drv.ms/f/c/409a77fcc169e845/IgBNWD1rCTAZT4px6JDCpw5BAc6_ZI4kxeg2Xc1Osx1yt6Q?e=bMpCBv 00:00 - Intro 02:29 - The Math 03:50 - Error Sources 11:57 - Common Point Traversing - Field 15:21 - Common Point Traversing - Office 21:41 - Is the Juice worth the Squeeze?
