Two-dimensional projection of a hyperspectral cube. Hyperspectral imaging collects and processes information from across the electromagnetic spectrum. [1] The goal of hyperspectral imaging is to obtain the spectrum for each pixel in the image of a scene, with the purpose of finding objects, identifying materials, or detecting processes.
Environmental Mapping and Analysis Program EnMAP is a German hyperspectral satellite mission to provide high accuracy hyperspectral image data of the Earth surface on a timely and frequent basis. It records data via a Sun-synchronous orbit at a height of 653 km above the Earth.
HICO collected hyperspectral satellite imagery of the Earth's surface from the ISS. [1] [2] [3] HICO was a pathfinder or proof-of-concept mission for hyperspectral imaging of the oceans, particularly for optically complex coastal waters. [4] The dataset collected by HICO serves as an example dataset for future hyperspectral satellite missions ...
In parallel, Pan (Panchromatic) imagery is provided at a spatial resolution of 5 m; the Pan data is co-registered with the Hyp (Hyperspectral) data to permit testing of image fusion techniques. [3] Internal Calibration Unit (ICU): an instrument designed to allow the support of absolute and relative radiometric calibrations and spectral ...
The technique was designed to put into practice the concept of 'tilted sampling' of the hyperspectral data cube, which had been deemed difficult to achieve. [4] Spatio-spectral scanning yields a series of thin, diagonal slices of the data cube. Figuratively speaking, each acquired image is a 'rainbow-colored' spatial map of the scene. More ...
This new package, named McIDAS-V, is a free, open source visualization and data analysis tool that displays weather satellite (including hyperspectral) and other geophysical data in 2- and 3-dimensions. McIDAS-V can also analyze and manipulate the data with its powerful mathematical functions.
Hyperspectral data is often used to determine what materials are present in a scene. Materials of interest could include roadways, vegetation, and specific targets (i.e. pollutants, hazardous materials, etc.). Trivially, each pixel of a hyperspectral image could be compared to a material database to determine the type of material making up the ...
Gaofen-5 has been lauded as the "flagship of the environment and atmosphere observation satellite in the CHEOS program". Launched on 8 May 2018 from Taiyuan Satellite Launch Center (TSLC) into Sun-synchronous orbit, Gaofen-5 carries six payloads: an Advanced Hyperspectral Imagery sensor (AHSI), Atmospheric Infrared Ultraspectral Sensor (AIUS), Directional Polarization Camera (DPC), Environment ...
