The use of multispectral cameras allows the acquisition of images at different wavelengths, visible infrared, near infrared and up to shortwave in different wide wavelength bands, allowing to identify the materials according to their spectral reflectance.
Hyperspectral imaging systems acquire images in over one hundred contiguous spectral bands. While multispectral images are useful for discriminating the characteristics of the earth’s surface and landscape models, hyperspectral images allow identification and characterization of materials. In addition to mapping the distribution of materials, the evaluation of individual pixels is often useful for detecting unique objects in the scene.
Different branch of scientific application include geology and mining exploration; forestry; marine exploration, of coastal areas, inland waters and wetlands, agriculture; urban survey, snow and ice; and the study of the atmosphere.
This offers the scientific community and users many applications in the field of environmental monitoring, agricolture, resource management, crop classification, and many more.
