A GPRS Case Study

GPRS Provides Point Cloud and 3D Mesh of Trees

Highlights

THE BOTTOM LINE

GPRS 3D laser scanned three 100-year old trees and provided the client with intensity map point cloud files and a 3D mesh of the trees to include them in the design plan.

Deliverables

GPRS provided the client with intensity map point cloud files and a 3D mesh of the trees. This can be pulled into an existing Revit or AutoCAD model and aligned with the design plan, as well as be used in reality capture software.

Task

The client desired to laser scan three 100-year old trees and include them in the design plans for a new development. GPRS 3D laser scanned the trees and provided the client with intensity map point cloud files and a 3D mesh of the trees for reality capture. This was GPRS’ second phase of laser scanning for this client.

PROBLEM

The client could not accurately capture the location, exact dimensions, and detail of the three trees. They needed laser scanning services to include the trees in the design plan. It was important to capture the existing conditions without damaging the tree trunks or limbs.

Solution

GPRS’ Texas office used a Leica C10 Scan Station to capture the three trees and the surrounding area. Accurate 3D measurements were captured in a few hours on site in a fast and environmentally friendly manner. Laser scanners are non-contact, they scan from tripods on the ground up to 300 yards, keeping the environment untouched.

Benefits

GPRS incorporated the first and second mobilization into the same coordinate system which allowed the separate projects to be put on the same coordinates and relate the projects to one another even though they were captured at different times. This allowed the client to create their design model more accurately and preserve the 100-year-old trees.

3D information is invariant to lighting and shadow. As a result, significantly more data was acquired by laser scanning the tree, and much more accurately than hand measuring. Laser scanning services are the solution for capturing spatial data in a fast, efficient and highly accurate way.
