Light Imaging Detection and Ranging

What Is LiDAR?

LiDAR uses the same principle as RADAR. The LiDAR laser sends a signal to the ground from an aircraft; some of this signal is sent (bounced) back to the aircraft; the time for the laser light to travel out to the ground and back to the aircraft is used to determine the distance to  the feature on the ground that it bounced off. A tree is going to be higher (taller) than the ground it is on; a house is going to be higher than the ground on which it was built. The "lay of the land" is recorded to a great accuracy.

All of the LiDAR Data available was collected in the Spring of 2007 as part of the

Statewide OSIP I Project.
