Fundamentals of Remote Sensing Imaging and Preliminary Analysis

Abstract

Airborne and satellite digital image acquisition, preprocessing, and data reduction techniques as applied to remotely sensed data for the purpose of extracting useful Earth resources information are discussed in this chapter. The image processing and postprocessing tools are described in the next chapter. The concepts discussed in this chapter include:Image acquisition considerations including currently available remotely sensed dataImage characteristics in terms of spatial, spectral, radiometric, and temporal resolutionsPreprocessing techniques such as geometric distortion removals, atmospheric correction algorithms, image registration, enhancement, masking, and data transformationsData reduction, fusion, and integration techniquesInternational policies governing acquisition and distribution of remotely sensed data
