The USGS held a Lidar Science Innovation Workshop (internal link) from 8/2 to 8/4 in Fort Collins, CO.

What is Lidar

Light Detection And Ranging, a way to measure distance with a laser light, used to make high-resolution elevation maps. (At varying resolution but commonly at approximately 1 meter resolution (an elevation point every square meter) with +/-10 centimeter vertical resolution => much higher resolution than people were used to previously.)
