Real-Time Certainty Flows in the Colorado River

How Trimble RTX correction service solution provided confidence and efficiency on land, air and water

Providing consistent, precise measurements on long, linear surveys can be a challenge. That challenge becomes even more acute when that linear survey is in a super remote river corridor.

That’s what one river engineering company faced for an aerial lidar topo-bathymetric survey. Using Trimble’s CenterPoint RTX positioning, the company is proving that PPP technology is a solid bet, whether it’s across remote lands, open skies or vast rivers.

“Having used Trimble’s CenterPoint RTX before, we were confident it would be good, but we didn’t know it was going to be that good.”


One would be hard pressed to find a river more important to a region than the Lower Colorado River in the United States — reportedly the river irrigates almost 90 percent of the nation’s winter vegetable crops. And yet, in April 2022, the Colorado River was designated the most endangered river in the country.

Recognizing the waterway’s unique significance and impact, the US Bureau of Reclamation (BOR) Lower Colorado Region issued a request for solicitation to survey and collect bathymetric and sediment data on 342 miles of the river system between Hoover Dam and Mexico.
