 So, Lidar. It's actually an acronym that stands for “Light Detection and Ranging”. It's a form of remotely-sensed data, meaning that the data is collected without direct contact with the study subject. In the case of Lidar, specialized sensors are mounted on an aircraft and flown over an area where data is to be collected. The sensor emits invisible beams of light, which bounce once they hit an object and are reflected back to the sensor. The sensor emits several million of these beams of light, called pulses, every second, and by collecting the return times of each pulse, it can put together a three-dimensional “image” of the ground below.

 This image, made of reflected pulses of light, is called a point cloud. Each point represents the spot where a pulse bounced off the ground, a tree, building, or other object. By aggregating these points together, we can put together a high-resolution image that can help us measure topography, elevation, vegetation, and much more. These images can be combined, or mosaicked, together to form larger maps of entire cities, counties, or, as of just a few weeks ago, the entire state of Utah.

-Collecting Lidar data is no simple task. You can take those aviator goggles off now; we won't actually be flying in any planes. That part has already been done by many vendors contracted by UGRC to collect Lidar data. In addition to the pilots collecting the data, UGRC has partnered with the [United States Geological Survey](https://www.usgs.gov/) to ensure the accuracy of the data. We also have spearheaded grant applications and a competitive bid process for our contractors. Through our partnerships with USGS and many others, we have been able to make high-resolution Lidar products available for every square inch of our beautiful state.

 So, why does it matter? There's already lots of data, even Lidar data, available for Utah. So why do we need high-resolution Lidar? Having higher resolution data doesn't just mean the picture looks nicer. It means that each pixel is a better representation of the real world; so when urban planners, construction managers, and everyday homeowners want to draft up a new building, they have more accurate data to work with.
