It is the United States' member organization of the International Society for Photogrammetry and Remote Sensing. Founded in 1934 as American Society of Photogrammetry and renamed in 1985, [ 1 ] the ASPRS is a scientific association serving over 7,000 professional members around the world.
The Indian Institute of Remote Sensing is an institute for research, higher education, and training in the fields of remote sensing, eco-informatics, and GPS technology for natural resources, environmental, and disaster management. The institute was established in 1966 under the Indian Department of Space. [2]
Geomatica includes a web coverage service interface that complies with the OGC Web Coverage Service (WCS) Interface Standard, which is a key area in which PCI Geomatics has contributed. Remote Sensing data providers distribute data in diverse formats, which makes sharing information across many different platforms challenging.
Quantitative remote sensing is a branch of remote sensing. The quantitative remote sensing system does not directly measure land surface parameters of interest. Instead, the signature remote sensors receive is electromagnetic radiation reflected, scattered, and emitted from both the surface and the atmosphere . [ 1 ]
Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object, in contrast to in situ or on-site observation. The term is applied especially to acquiring information about Earth and other planets .
Remote sensing systems gather data via instruments typically carried on satellites in orbit around the Earth. The remote sensing scanner detects the energy that radiates from the object or area of interest. This energy is recorded as an analog electrical signal and converted into a digital value though an A-to-D conversion.
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.
Radio occultation (RO) is a remote sensing technique used for measuring the physical properties of a planetary atmosphere or ring system. Satellites carrying onboard GNSS-Radio occultation instruments include CHAMP , GRACE and GRACE-FO , MetOp and the recently launched COSMIC-2 .
