The UK Environment Agency has announced an ambitious plan to map the entire country, which covers an area of about 130,000 square kilometers. To make this step easier, they will use a plane equipped with a laser scanner.
In the project, which will take place over the next three years, the British government will use light detection and ranging (LIDAR) technology to survey the entire country at a resolution of one meter.
In the future, all data will also be freely available to the public, as is the case with current LIDAR data. Laser engraving metal In the last two years, the public has downloaded LIDAR data from open survey sites.
“I am delighted to be able to collect, use and share valuable data to contribute to environmental improvement and conservation,” said Sir James Beven, head of the agency.
Besides being useful for planners and environmentalists, LIDAR data can also be used for various purposes, such as game development or creating 3D sculptures of the city of London. In 2016, for example, archaeologists used LIDAR images to find ancient Roman roads that had been “lost” for centuries.
Newer LIDAR technology allows aircraft to fly at higher altitudes, cover larger areas more consistently and produce higher quality digital models. Most surveys will be conducted during winter, when the absence of tree leaves means laser pulses can reach the ground.
“This ambitious project will enhance our understanding of Britain’s unique natural features and landscapes, helping us to better understand flood risk, plan effective defenses and combat waste crime.”
For your information, about 40 percent of the UK territory, has not been surveyed, or only mapped with a resolution of two meters.
Electrons that have moved to a higher energy level (excited electrons) are in an unstable state. These electrons always try to return to their initial state by releasing the excess energy. The energy released is in the form of photons (light energy) which have a certain wavelength (certain color) according to their energy level. This is called atomic radiation. In a flashlight or ordinary fluorescent lamp, the light produced goes in all directions and has various wavelengths and frequencies (incoherent light). The result is a very weak light
