Aerial Lidar in it's simplest terms is flying an aircraft above ground while taking multiple measurements. The planes location is known at all times and measurements to the ground are taken with a laser. The laser sweeps side to side as the plane moves forward. The planes location is tracked using Multiple GPS receivers and an Inertial Measurement Unit (IMU).
For the CHaMP program meshing the topo surveys to the Airborne Lidar surveys can be accomplished by an additional Lidar Integration Control Survey (LICS). During the Lidar flight a GPS receiver on the ground occupies a control point. This Lidar control point is where the Lidar Integration control survey begins. The LICS crew will occupy the control point and survey the CHaMP benchmarks. If the CHaMP sites are close to the Lidar control point this will be fairly simple, but as we all know the distance may be significant and there will be many obstacles in the way.

Here is an example of where CHaMP sites are within the area of a previous Lidar data collection event.
June 3rd 2015: I did a presentation about integrating lidar data with Champ ground based survey data to the Champ collaborators. Click Here for the pdf.
Lidar is a new invention of the technology that can measure the distance of the surface of the earth using laser light. The measurement of lidar is unbeatable. If you need the best lidar scanner service in Texas. Lidar Houston, Texas
