Hovermap PPK: Pedestrian and Vehicle Bridges, Mount Crosby Weir

Written by Katie Koss | Jun 3, 2026 3:00:20 AM

This dataset captures the pedestrian and vehicle bridges at Mount Crosby Weir, west of Brisbane, Australia, scanned with Hovermap STX and georeferenced using PPK (Post-Processed Kinematic).

The pedestrian bridge was captured using Emesent's Backpack RTK kit, while the vehicle bridge was captured with Vehicle RTK. Rather than relying on a real-time RTK correction stream — challenging at this riverside location — both scans were corrected in post-processing using logged GNSS observations, then non-rigidly merged in Emesent Aura into a single seamless point cloud. See the entire process -from field capture to point cloud - in this PPK walkthrough video.

PPK gives surveyors a reliable path to accurate georeferencing in locations where real-time communications are unavailable or unreliable. Scans can be captured with confidence in the field, with GNSS fixes computed offline from logged data — eliminating connectivity dependencies and troubleshooting delays.
