COORDINATED SOLUTIONS
Two weeks before the shutdown, SAK used Trimble
®
R10
GNSS receivers and a Trimble S8 1" total station together
with Trimble Business Center software to establish more
than 150 points to control aerial imaging and ground-based
measurements.
As soon as the canal was drained, SAK commenced work
using a Trimble UX5-HP unmanned aircraft system (UAS).
They completed eight missions over two days and captured
nearly 5,100 images covering the entire length of the project.
SAK designed the aerial work to move quickly. At the end of
each flight, data was immediately taken by motorcycle to the
SAK office while the aircraft was readied for its next flight.
Using Trimble UASMaster software technicians could produce
finished orthoprojections of the site in roughly seven hours
after the raw data arrived. In areas where the canal passed
through tunnels they used a Trimble TX8 laser scanner to
collect 3D information. SAK needed only two days to capture
comprehensive data for the entire channel.
As construction progressed, SAK scanned each completed
segment with the TX8. They complemented the scanning
with total station measurements to georeference the scans
and capture parts of the channel that were beneath bridges
or still underwater. The UAS, scanning and point data
were combined into Trimble RealWorks
®
software for data
management and analysis.
