Volume IV, Advanced Applications in Remote Sensing of Agricultural Crops and Natural Vegetation discusses the use of hyperspectral or imaging spectroscopy data in numerous specific and advanced applications, such as forest management, precision farming, managing invasive species, and local to global land cover change detection. It emphasizes Author: Prasad S. Thenkabail, John G. Lyon, Alfredo Huete. Fluorescence imaging is a method of real-time molecular tracking in vivo that has enabled many clinical technologies. Imaging in the shortwave infrared region (SWIR, μm) promises higher contrast, sensitivity, and penetration depths compared to conventional visible and near-infrared (NIR) fluorescence imaging. However, adoption of SWIR imaging in clinical settings has been limited, due in Cited by:

A portion of radiation that is just beyond the visible spectrum is referred to as near-infrared. Rather than studying an object's emission of infrared, scientists can study how objects reflect, transmit, and absorb the Sun's near-infrared radiation .

Shortwave infrared sensors were included on Thematic Mapper to observe vegetation reflected radiance patterns that are related to leaf water content. However, there was some uncertainty whether these measurements would increase the information content of multispectral measurements beyond that provided by visible and near infrared by: 8.

Sensing in the shortwave infrared (SWIR) range (wavelengths from to microns) has only recently been made practical by the development of Indium Gallium Arsenide (InGaAs) sensors. Sensors Unlimited, Inc., part of UTC Aerospace Systems, is the pioneer in this technology and clear leader in advancing the capability of SWIR sensors.
Short-wave infrared 2. This band is mainly helpful for discriminating among different types of rock formations. It can also be used to measures the infrared radiant flux (heat) amount emitted from the surfaces. Near-infrared band. This band is particularly responsive to the vegetation biomass that is present in the image.
Midwave Infrared (MIR) ranges from 3, to 5, nanometers and is most often used to study emitted thermal radiation in the dark of night. Midwave infrared energy is also useful in measuring sea surface temperature, clouds, and fires. The images below contrast a visible-light nighttime view of the Niger River Delta with the same view in midwave infrared; both images are from the Visible Author: Holli Riebeek.
The water in green vegetation is detectable using reflectances in the near infrared and shortwave infrared. Canopy water content is estimated from the product of leaf water content and leaf area. Vegetation water content is an important biophysical parameter for estimation of soil moisture from microwave radiometers.
One of the objectives of the Soil Moisture Experiments in (SMEX04) and (SMEX05) were to develop and test algorithms for a vegetation water content data product using shortwave infrared reflectances. Healthy vegetation absorbs red and blue light for photosynthesis.
Some of the green light and a high percentage of shortwave infrared light is reflected off the leaves. What we don’t see, however, is that healthy plants actually reflect more near infrared (short wavelength infrared) than visible green.
In this study, a subpixel vegetation cover of coniferous forests in Oregon, United States, was successfully estimated by employing shortwave infrared reflectance measurements (SWIR2 region, Encompasses hyperspectral or imaging spectroscopy data in narrow wavebands used across visible, red-edge, near-infrared, far-infrared, shortwave infrared, and thermal portions of the spectrum.

Wooster, Gareth Roberts, Alistair M.S. Smith, Joshua Johnston, Patrick Freeborn, Stefania Amici, and Andrew T. Hudak Abstract Thermal remote sensing is widely used in the detection, study, and management of biomass burning occurring in open vegetation by: Simple Ratio (SR) Vegetation Index The near-infrared (NIR) to red Simple Ratio (SR) is the first true vegetation index: Takes advantage of the relationship between high absorption by chlorophyll of red radiant energy and high reflectance of near-infrared energy for healthy leaves and plant canopies.
SR = R NIR / R R 17 Optical PropertiesFile Size: 6MB. Vegetation pops in red, with healthier vegetation being more vibrant in this band combination. It is easier to tell about different types of vegetation apart than it is with a natural color image.
This is a very commonly used band combination in remote sensing when looking at vegetation, crops, and wetlands. shortwave infrared drought index for monitoring soil and vegetation moisture based on optical remote sensing, International Journal of Remote Sensing, DOI: / Monitoring crops using infrared photography has been possible for many years.
Using drones or uav's makes capturing an area from the air much simpler and more cost effective than ground based methods. The images captured by the UAV can be used to calculate NDVI and other plant health indexes.
possesses to improve detection, identification, and tracking performance.1 The shortwave infrared band, here defined as to micron, was selected as it has superior transmission characteristics through marine haze compared to the visible waveband and produces an image of comparable quality relative to visible sensor systems.
The shortwave infrared market (SWIR) is expected to be valued at USD million in and is likely to reach USD million byat a CAGR of % during the forecast period. High demand for SWIR products from the nonindustrial vertical is one of the major factors driving the growth of the shortwave infrared market.
Introduction. Cotton is an important living material produced globally, and cotton quality directly affects its potential profitability. China, India and the United States are the top three raw cotton producers, and combined they provide two-thirds of cotton produced globally (Zhang et al., ).Although the United States ranks third behind China and India in production, it is the largest Cited by: 7.
