Surveyors Wield Picture-Perfect Productivity

Psomas Survey Crew Chief Matt Davis prepares to measure building corners and height using the Trimble S8 with Trimble VISION at the Trimble TSC3 controller. Images are captured at the building corner locations.

Capturing pictures in the field has come a long way from sketchbooks and Polaroid photos. As integrated imaging enters the mainstream of modern fieldwork, surveyors are finding new applications and impressive cost savings.

Surveyors long ago embraced digital photography as a way of enhancing the point-based data collection process. But the real benefits emerge when images and video in the field are integrated into both field and office workflows. That’s exactly where imaging technology is headed.

Jeremy Evans, Psomas technical director for land surveying and mapping, and Sean Logal, Psomas project surveyor, discuss how, using advanced survey instruments equipped with Trimble VISION technology, Psomas is able to capture digital images and utilize real-time video in the field.

Surveying from a safe location.

Psomas Survey Party Chief Fulton Torreyson controls the Trimble VX from a safe location. The imaging technology lets Torreyson use the data collector display to “look” through the instrument telescope.

As the article explains:

“For surveying applications, imaging technology integrates calibrated digital cameras into surveying field instruments. It provides the ability to collect survey data, stream video and capture panoramic still images that are oriented into the project coordinate system. In the field, software overlays survey data on the images to enable the operator to see things from the instrument’s perspective and assist in robotic operations. In the office, software overlays survey data on the panoramic images for analysis and quality control. Some systems even provide photogrammetric processing to make precise measurements from the photos.”

The opportunities presented by the multi-purpose spatial stations grow larger by the day. Logal calls it “a fruit salad” of data. “We’ve got so many different data sets coming from different sources,” he says. “It’s incredible how robust the data sets are and how much additional information we can produce.”
