LiDAR
Last Review/Updated: October 24, 2007
LiDAR stands for Light Detection and Ranging. It is a new technology used to create a 3D profile of the ground.
LiDAR uses optical remote sensing to measure properties of scattered light to determine range and other information of a distant target. Like radar technology (which uses radio waves instead of light), LiDAR determines the range to an object by measuring the time delay between transmission of a laser pulse and detection of the reflected signal. LIDAR technology can be applied in the fields of archaeology, geography, geology, seismology, remote sensing and atmospheric physics.
A highly accurate digital elevation model is just one example of a product that can be created from LiDAR imagery. In order to take full advantage of LiDAR, Alberta Government agencies need to be made aware of possible uses and the specifications required to enable those uses to be made of the data.
