Typical data collected includes aerial photography, Lidar, remote sensing (using various visible and invisible bands of the electromagnetic spectrum, such as infrared, gamma, or ultraviolet) and geophysical data (such as aeromagnetic surveys and gravity measurements). It can also refer to a chart or map made by analyzing a region from the air.
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.
[1] [2] Once mounted on a helicopter or an unmanned aerial vehicle (UAV), it incorporates visual information from a digital camera and elevation data from a Light Detection and Ranging (LIDAR) system to create a two and three-dimensional colored map with orthorectified, 4 to 6-inch resolution. [3]
LIDAR can be used to detect ground surface changes. [10] Vegetation remote sensing is a principal application of LIDAR. [11] Radiometers and photometers are the most common instrument in use, collecting reflected and emitted radiation in a wide range of frequencies. The most common are visible and infrared sensors, followed by microwave, gamma ...
Geological structure measurement by LiDAR technology is a remote sensing method applied in structural geology. It enables monitoring and characterisation of rock bodies. [ 1 ] This method's typical use is to acquire high resolution structural and deformational data for identifying geological hazards risk, such as assessing rockfall risks or ...
The company released its first drone called X-Star in 2015 in global markets and has other notable product lines, including the Evo and Dragon Fish series. [3] In 2021 Autel Robotics had a 7% share of the UAV market in the United States. [5] Its market share increased after leading rival DJI was restricted by the US government. [5]
An autonomous aircraft is an aircraft which flies under the control of on-board autonomous robotic systems and needs no intervention from a human pilot or remote control.Most contemporary autonomous aircraft are unmanned aerial vehicles (drones) with pre-programmed algorithms to perform designated tasks, but advancements in artificial intelligence technologies (e.g. machine learning) mean that ...
The first RQ-4D aircraft arrived at Sigonella Air Base on 21 November 2019. At that time, all five aircraft were undergoing developmental test flights. Initial operational capability was expected in the first half of 2020. [127] In October 2018, Italy certified five of the drones for use in Sigonella, Sicily in 2020.
