In the case of lidar, the waves are in the form of an infra-red laser beam.
These include GPS, stereo cameras, radar and Light Detection and Ranging (LIDAR) laser tracking.
Lidar monitoring may provide a way of making sure it is delivering on its side of the bargain.
The electronics in your radar or laser detector work no faster than those in my radar or LIDAR gun.
FORBES: What Are Some Things That Cops Know, But Most People Don't?
During a forest survey, an aircraft-borne lidar sweeps a beam that fires about 70, 000 pulses a second over the canopy.
LiDAR fires thousands of laser pulses per second at the ground.
Like its cousins radar and sonar, lidar (light detection and ranging), works by broadcasting electromagnetic waves towards a target and then building up a picture from the reflection.
Equipped with high-definition infrared cameras and ranging (LiDAR) sensors, Ti feeds information to the utility about specific conditions of specific assets at specific places on a transmission line.
FORBES: Strong Grid: Are Radical Robotics the Secret Ingredient?
The approach du jour for most researchers is something known as Light Detection and Ranging ( LIDAR) -- a laser-based technology capable of creating precise maps over relatively large areas.

In Caithness, LiDAR revealed fields where medieval and later rig and furrow systems overlie much earlier agricultural use as well as the remains of 3, 000-year-old low-walled, thatched roofed houses called hut circles.
Mapping nearby features, spotting road edges and lane markings, reading signs and traffic lights and identifying pedestrians is done using a combination of cameras, radar and lidar (which works like radar, but with pulses of light rather than radio waves).
And that, in turn, can be used to estimate the amount of carbon stored in the plot examined, and extrapolated to calculate the carbon stored in larger areas of forest that have been scanned by lidar, but not measured with tapes.
Otherwise, you can expect a 1:2.2 pan sharpen ratio, and the ability to collect RGB and NIR in parallel with forward motion compensation by TDI, which will let you use the camera in a whole host of applications ranging from orthophoto production to corridor mapping to lidar integration.

Until a few years ago, assessing the amount of plant matter in a forest in a cheap and accurate manner seemed an insurmountable problem, according to Eric Dinerstein, chief scientist of the World Wide Fund for Nature, a conservation group that is also involved in the Nepalese lidar project.
