A national lidar dataset refers to a high-resolution lidar dataset comprising most—and ideally all—of a nation's terrain. Datasets of this type typically meet specified quality standards and are publicly available for free (or at nominal cost) in one or more uniform formats from government or academic sources.
Lidar (/ ˈ l aɪ d ɑːr /, also LIDAR, LiDAR or LADAR, an acronym of "light detection and ranging" [1] or "laser imaging, detection, and ranging" [2]) is a method for determining ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver.
Along with climate and corresponding types of vegetation, the economy of a nation also influences the level of agricultural production. Production of some products is highly concentrated in a few countries, China, the leading producer of wheat and ramie in 2013, produces 95% of the world's ramie fiber but only 17% of the world's wheat. Products ...
Location of the province of Almeria (Spain). The intensive agriculture of the province of Almeria, Spain, is a model of the utilization of highly technical means to achieve maximum economic yield based on the rational use of water, use of plastic greenhouses, highly technical training and high levels of employment of inputs, applied to the special characteristics of a particular environment.
Essentially, the DELICAT program calls for planes to be equipped with a light detection and ranging instrument (LIDAR) that emits short-wave ultraviolet lasers. Radiation then bounces off oxygen ...
Diode lasers are used as a lightswitch in industry, with a laser beam and a receiver which will switch on or off when the beam is interrupted, and because a laser can keep the light intensity over larger distances than a normal light, and is more precise than a normal light it can be used for product detection in automated production. Laser ...
The number of farms decreased steadily in West Germany, from 1.6 million in 1950 to 630,000 in 1990. In East Germany, where farms were collectivized under the socialist regime in the 1960s, there had been about 5,100 agricultural production collectives, with an average of 4,100 hectares under cultivation. Since unification, about three-quarters ...
Imaging radar is an application of radar which is used to create two-dimensional images, typically of landscapes. Imaging radar provides its light to illuminate an area on the ground and take a picture at radio wavelengths. It uses an antenna and digital computer storage to record its images.
