Behind the Big Eye of the SX10

Behind the distinctive “bug eye” of the SX10 is the spinning prism for scanning, a tracking laser, EDM laser, a tele-camera, and tracking camera. Flanking the lens is the overview camera (left) and primary camera (right), and a plummet camera underneath.

Gavin Schrock, land surveyor, technology writer, and xyHt editor, was lucky enough to visit the Danderyd, Sweden, facility of Trimble to share the story of the SX10 and its development.

Ingenuity to create solutions clients can’t live without

Working for tier-one construction companies, Todd Foster’s focus on high-accuracy, innovative spatial solutions started with high-accuracy monitoring on two large dam projects.

After the second dam was complete, Todd decided to venture out on his own by starting Milestone Survey. By blending traditional survey techniques with innovative ways of problem solving, Milestone Survey has grown into a strong player in the Australian market – even in a slowing economy.

Todd has built a company that uses innovation, talented employees, and leading-edge survey equipment to deliver value to its clients by anticipating the clients’ needs. It’s this ingenuity and ability to create solutions that clients can’t live without that will ensure the success of this new venture, Milestone Spatial, for a long time to come.

See how he has done that in the latest Trimble technology&more magazine.

Surveying a highway without setting foot on the road

There’s a lot going on at the intersection of Pumicestone and Beerburrum Roads, just north of Caboolture, Queensland.

Traffic is continuous, and just 30 metres to the east, trains bustle along the North Coast railway line.
With this in mind, Transport and Main Roads (TMR) needed to consider surveyor safety before starting a major upgrade in the area.

Would its team be confined to night surveys with expensive traffic control? Or was there a way to remotely capture the extensive but vital site data without putting surveyors on the road?

“We’d usually need to occupy the road with a total station and prism, and no risk assessment would allow us to do that without traffic control at the very least, so we’d probably end up doing the job at night,” said TMR senior surveyor Ray Miller.

Overall, the risks of the job would take time and cost to mitigate.

“As well as the survey crew, you’ve got at least three traffic controllers plus bump trucks, lights, set-up, and signs, plus Queensland Rail would need to be informed and they have their own controls and procedures for safety.

“It becomes a time-consuming logistical challenge,” said Ray.

However Ray and his team found a way to survey its entire Bruce Highway project during the day without setting foot on the road.

See how in this case study.

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.
