Also, it makes outflow boundaries findable within visible satellite imagery as a thin line of cumuliform clouds which is known as an arcus, or arc, cloud. The image to the right depicts a particularly strong outflow boundary ahead of a line of storms. Often, the outflow boundary will bow in the direction it is moving the quickest. [4]
Imagery intelligence (IMINT), pronounced as either as Im-Int or I-Mint, is an intelligence gathering discipline wherein imagery is analyzed (or "exploited") to identify information of intelligence value. [1] Imagery used for defense intelligence purposes is generally collected via satellite imagery or aerial photography.
Sputnik 1 (/ ˈ s p ʌ t n ɪ k, ˈ s p ʊ t n ɪ k /, Russian: Спутник-1, Satellite 1) was the first artificial Earth satellite.It was launched into an elliptical low Earth orbit by the Soviet Union on 4 October 1957 as part of the Soviet space program.
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.
The Visible Infrared Imaging Radiometer Suite (VIIRS) is the largest instrument aboard of Suomi-NPP (National Polar-Orbiting Operational Environmental Satellite System Preparatory Project). It collects radiometric imagery in visible and infrared wavelengths of the land, atmosphere, ice, and
Chandrayaan-2 image of the Lunar Module Eagle descent stage at Tranquility Base. In April 2021 the ISRO Chandrayaan-2 orbiter captured an image of the Apollo 11 Lunar Module Eagle descent stage. The orbiter's image of Tranquility Base, the Apollo 11 landing site, was released to the public in a presentation on September 3, 2021. [5]
Both features can be seen on visible satellite imagery, during daytime, by the shadows they cast on surrounding clouds. In multicellular storms and squall lines, the mid-level jet stream is often intersecting the line and its dry air introduced into the cloud is negatively unstable. This results in drying of the cloudy air in the region where ...
High-resolution satellite imagery (1 metre and less) has been available since 1999, [3] [4] but its use for North Korean studies did not emerge until 2012. [1] By 2004, researchers and NGOs had imaging and computing capabilities comparable to those available to the US government 20-30 years earlier, in the 1970s.
