Another Lidar and Sonar Flythrough

Here's another video of the same as below.  I've colored the river bottom data in an elevation banding mode making it clearer to see the river bottom data.  We are doing full 3D mapping extraction for all features and DTM breaklines from the point cloud as well.  Once that's wrapped up, I'll share some shots showing the extracted data along with the point cloud data.

3D Feature Mapping From Mobile Lidar Point Clouds

Here's a video of a 7 mile freeway project we recently completed.  Full 3D survey grade feature extraction from a mobile lidar dataset.  6 lanes of barrier divided freeway surveyed without closing lanes or placing surveyors in the roadway.

Here's a video of a 1.5 mile stretch of I-75 Northbound in Detroit.

Topcon IPS-2 HD Accuracy Test

We recently did some testing with the latest Topcon IPS-2 HD mobile lidar system.  We had a section of freeway that we recently completed a mobile lidar project for using a Reigl VMX-250.  Since we had precise survey control in place with many of the painted chevrons still in place, we took the opportunity to test the latest Topcon system under the same conditions as the Reigl system. While we had the Topcon system in possession, we took the opportunity to collect some amazing lidar data on a few other projects as well.  In the upcoming weeks I will share the results from our testing as well as some of the other data we collected.
