Each band has a spatial resolution of 30 meters except for bands 8, 10, and 11. While the panchromatic band has a spatial resolution of 15 meters, its thermal bands have a 100-meter pixel size. Summary: Spatial
spatial resolutionspectral imagingAn acousto-optic tunable filter (AOTF) causes the diffracted angle and wavelength to spread, leading to loss of resolution. The light intensity detected by a CCD pixel equals the true intensity plus the stray light caused by the spread of the wavelength and ...
The resolution of an image signifies the potential detail provided by imagery. There are four different types of resolution: • spatial • spectral • radiometric • temporal 9.1.2.1Spatial resolution Spatial resolution refers to resolving the power of the sensor for distinguishing among the clo...
The videospectrometric included a CCD television camera with high sensitivity (optical resolution 400 lines mm−1, spatial resolution of 500 × 582 elements), a photographic camera PRAKTICA, a high-resolution multichannel spectrometric system “Spectrum 256”, a photometer J16 Tektronix, a computer ...
habitats. For example, the brain could consider certain parts of the sensory information to be more reliable than others, and hence put different weights on different frequency bands. Conversely, it could exclusively process only those parts of the spectrum that yield an optimal spatial resolution....
(Fig.3d, e and Supplementary Fig.3e, f). Thus, in addition to being a qualitatively novel observable, pACF also yields insight into the architecture of oscillations by overcoming the intrinsic resolution limitations of the power-based analysis. This might be because a purely single-frequency ...

Chandrayaan-1 initially settled into a circular polar orbit, approximately 100 km above the lunar surface, thereby providing a spatial resolution of ~ 80 m/pixel and a swath width of ~ 20 km. From its vantage point, HySI has a nominal field of view of ~ 13°. Using this...
1 In the following sections, we use it to describe the spatial and spectral response characteristics of a remote-sensing imaging system. 3.3.2 Spatial Resolution While the spatial “resolution” of a sensor (or its image) is often quoted as the GSI or GIFOV, it is well known that it is...
For a given UAV image, the appropriate patch size is related to its spatial resolution, spectral resolution, and feature distribution characteristics. To achieve efficient detection, choosing a suitable patch size acts as the important first step. In the study area, different patch sizes were set,...
