What is Spectral Resolution

Chapter 303
Encyclopedia of Information Science and Technology, Fourth Edition
Different classes of features and details in an image can often be distinguished by comparing their responses over distinct electromagnetic wavelength ranges. Spectral resolution describes the ability of a sensor to define fine wavelength intervals.

Abstract
The first human footprints dated more than 1, 9 million years ago; the Homo erectus Era; ‘upright man'; marks the beginning of man socio-economic-Historical Development. It culminated to Bronze Age, Iron Age, Industrial Revolution and currently Information Age. The current Era has allowed rapid global communications and networking to shape modern society. Individuals are able to transfer information freely, with instant access to knowledge that would have been difficult/ impossible previously. This chapter elaborates upon GIS/Remote Sensing; the highest echelon in ICT world. It compares and contrasts the four globally used GIS systems of GOES: the Geosynchronous Orbiting Environmental Satellite; LANDSAT, SPOT: Satellite Pour l'Observation de la Terre and the WorldView. Their temporal resolution; spatial resolution (Figure 6 – WorldView3); spectral resolution (Figure7 Landsat8); radiometric resolution (Figure8 WorldView3) and their DEM characteristics (Figure9 SPOT DEM) are reviewed. The human side of information reference services in the form of TEK is alluded to.
