The Remote Identification of Terrain Features and Materials at Kansas Test Sites:An Investigative Study of Techniques.

摘要

The report documents the collection,processing,and analysis of multispectral data gathered in airborne flights over three test sites in northeastern Kansas during the early spring of 1970. The overall objective for this investigation,as well as for others covered by the same contract,is to develop techniques for automatically identifying,in remotely sensed multispectral imagery,selected terrain features and natural materials. Specific objectives of the studies reported were to (1) classify automatically soils of different textures or parent materials based on their spectral reflectance characteristics, (2) detect a subsurface cavity in a suburban area of Kansas City,and (3) attempt to evaluate the condition of concrete pavement and bridge decks along a section of Interstate 35. The first objective was achieved during the period covered by this report;the other two were not. (Modified author abstract)
