Intro to Multispectral Imaging

Originally developed for military target identification and reconnaissance, multispectral imaging uses specific wavelengths of the electromagnetic spectrum to document environmental features of interest. Early NASA imaging of Earth from space incorporated multispectral imaging technology to map details related to oceans, landforms, and vegetation. More recently, modern weather satellites now produce diagnostic imagery using multispectral sensors. Today, multispectral imaging is used by the U.S. military to detect landmines and underground missiles. By analyzing disturbed soil features with multispectral imaging, different physical and chemical properties can be detected. Likewise, multispectral imaging of the invisible radiation emitted during intercontinental ballistic missile launches can track their trajectories. Multispectral imaging is also used to interpret ancient papyri and other ancient documents by imaging the documents in the infrared range. Typically, writing …
