Surveying earthquake damage to restore tourism

There has been extensive seismic activity in New Zealand over the last few years. In November there was another significant earthquake in the South Bay Marina, on the South Island.

The South Bay Marina and surrounding area in Kaikoura is a popular area for tourism and commercial fishing. However the earthquake has disrupted this activity with seabed uplift.

Areas that were previously channels for fishing or tourism boats to make their way into open water are now reduced to narrow passages, only usable at high tide.

Eliot Sinclair were approached to survey the damage after the earthquake and to re-establish chart datum.

 

 

Scanning Brisbane’s Gateway Bridge – in half the scans

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.

See more of the scans from the Trimble SX10, or register for a demo.

UPG would like to thank Tim Gahan from QRGF for his assistance in making the Gateway Bridge survey possible.

Deliver more productivity and flexibility

Geospatial professionals can use scanning and imagery to deliver significant gains in productivity and flexibility for their clients.

3D laser scanners are capturing more points with greater precision. Software is managing this data with less human input using automated registration and classification, and automated modelling.
