Hyperspectral imagery from DESIS
Multispectral imaging cameras have long been used for land use mapping, agriculture monitoring, vegetation classification, water and wetland study, marine and coastal ecosystem analysis, urban observation, and atmospheric analysis. However, hyperspectral sensors, with their higher spectral resolution and greater number of spectral bands, allow for improved identification and characterization of remotely sensed materials due to their ability to identify and quantify molecular absorption. This higher spectral resolution allows for more refined and unique Earth observations including mineral mapping, soil property classification, water quality, and marine litter, in addition to the above listed multispectral uses.
I2R offers processing and calibration/validation of hyperspectral remote sensing imagery at all stages of acquisition, from pre-launch characterization to post-acquisition processing.
