WorldView-2 - Earth Online - European Space Agency
WorldView-2 provides commercially available panchromatic imagery of 0.46 m resolution, and eight-band multispectral imagery with 1.84 m resolution - representing one of the highest available spaceborne resolutions on the market.
WorldView-3 - Earth Online - European Space Agency
WorldView-3 is an imaging and environment-monitoring satellite from Maxar of the United States which launched on 13 August 2014 and remains operational. It is very similar to WorldView-2 but positioned in a lower orbit. WorldView-3 was the first mission to carry a multi-payload, super-spectral, high-resolution commercial satellite sensor.
Multispectral imaging - Wikipedia
Multispectral imaging captures image data within specific wavelength ranges across the electromagnetic spectrum. The wavelengths may be separated by filters or detected with the use of instruments that are sensitive to particular wavelengths, including light from frequencies beyond the visible light range (i.e. infrared and ultraviolet ).
Multispectral Vs. Hyperspectral Imaging: Differences And Uses
2024年3月22日 · Multispectral satellite constellations collect data throughout a limited portion of the electromagnetic spectrum (five to ten bands); typically, it’s RGB (red, green, and blue — the three primary colors) and a handful of infrared bands. Hyperspectral satellites are able to distinguish thousands of individual light spectrum bands.
Sentinel-2: Satellite Imagery, Overview, And Characteristics
2021年12月15日 · The satellite is equipped with an opto-electronic multispectral sensor for surveying with a sentinel-2 resolution of 10 to 60 m in the visible, near infrared (VNIR), and short-wave infrared (SWIR) spectral zones, including 13 spectral channels, which ensures the capture of differences in vegetation state, including temporal changes, and also min...
Multispectral Image - an overview | ScienceDirect Topics
A multispectral image is a collection of a few image layers of the same scene, each of them acquired at a particular wavelength band. The well-known high-resolution visible sensor operates in the 3-band multispectral detects radiations in the following wavelengths bands:
Panchromatic And Pansharpened Satellite Imagery - EOS Data …
2021年9月24日 · Panchromatic images are produced by the same satellites that produce multispectral images – Landsat, DigitalGlobe’s range of satellites, SPOT6/7, and more.
Introduction to Spatial and Spectral Resolution: Multispectral Imagery ...
2020年3月30日 · Welcome to the first lesson in the Multispectral imagery in R - Fire & Remote Sensing Data module. In this module, you will learn how to use multispectral imagery, a type of remote sensing data, to better understand changes in the landscape and how to calculate NDVI using various multispectral datasets You will also review spectral remote ...
Multispectral | European Space Imaging
With hundreds of current applications and countless more waiting to be discovered, multispectral imagery is the key to unlocking insights in any industry. European Space Imaging captures imagery with up to 8 multispectral bands plus the ability to collect imagery in Shortwave Infrared (SWIR) and hyperspectral as well.
