Requirements on optical sensors for quantitative definition of surface parameters multispectral - hyperspectral Original Research Article

New sensors allow a significant progress in remote sensing from qualitative interpretation of data to quantitative assessment and characterisation of the status of surface targets and phenomena. Gathered knowledge of band positioning, bandwidth and number of spectral bands in optical remote sensing allowed to improve the physical characteristics of existing and future sensors: SPOT 4/5, MOMS 02/2P, IRS-1C, LANDSAT 7, hyperspectral sensors on EO-1 HRST and HYMAP/ARIES etc. Improvements in radiometric sensor calibration, atmospheric corrections and digital evaluation methodology widen the possibilities for quantitative analysis of the data for different applications.
