Scanning one of Brisbane’s Sir Leo Hielscher Bridges is no small task. The first of the bridges, formally known as the Gateway Bridge, is 1.6 km long.
However some of our surveyors have recently captured the bridge with the Trimble SX10 demo unit and with half as many scans as you might expect.
They were able to do the survey with 10 station set ups and thirteen scans. The results were processed in Trimble Business Center and UPG staff were impressed.
“Previously we would have had to scan the bridge using twice as many set ups to ensure sufficient overlap to successfully register the data. Alternatively we could have captured the bridge as a topographic survey,” commented one surveyor. “Either way we would have been in for a lot more work to even get close to the same result”.
The demo unit has been around the country, also scanning the Melbourne War Memorial.
UPG would like to thank Tim Gahan from QRGF for his assistance in making the Gateway Bridge survey possible.
