Using LiDAR to Capture Site Data

Accurately capturing elevation changes and landscape elements in the traditional way requires expertise, takes time, and is error prone. Using a mobile LiDAR generates a more complete, and precise data set that can be used to place elements accurately.

Step One: Walk the site with a SLAM (simultaneous location and mapping) LiDAR scanner to capture a digital point cloud.

Laser site point cloud

It took less than 10 minutes to capture the site details for this barn renovation project in the California Wine Country. The point contains over 50 million individual measurements. The resulting point cloud can be stored, viewed, and measured in HELIX without any additional software, and can be shared with the project team, clients, and as part of a bid solicitation package.

Step 2: Convert the point cloud into a 3D mesh

After cutting the point cloud into sections and removing elements that are unrelated to the site contours we generate a clean, accurate mesh model of the site.

Step 3: Extract contour lines

Contour lines extracted from a site mesh model.

This site has a relatively small change in grade so we created contour lines to show 2' elevation changes. This process only takes a few minutes.

Step 4: Place model on the site

A LiDAR-based site model makes it easy to quickly and accurately place a building on its site and locate walls, trees and exterior structures. The total time required was less than an hour.
