Remote Sensing and Cognition


Book Description

Human factors play a critical role in the design and interpretation of remotely sensed imagery for all Earth sciences. Remote Sensing and Cognition: Human Factors in Image Interpretation brings together current topics widely recognized and addressed regarding human cognition in geographic imagery, especially remote sensing imagery with complex data. It addresses themes around expertise including methods for knowledge elicitation and modeling of expertise, the effects of different aspects of realism on the interpretation of the environment, spatial learning using imagery, the effect of visual perspective on interpretation, and a variety of technologies and methods for utilizing knowledge in the analysis of remote sensing imagery. Written by leaders in the field, this book provides answers to the host of questions raised at the nexus of psychology and remote sensing. Academics and researchers with an interest in the human issues surrounding the use of remote sensing data will find this book to be an invaluable resource. The topics covered in this book are useful for both the scientific analysis of remote sensing imagery as well as the design and display of remote sensing imagery to facilitate a variety of other tasks including education and wayfinding. Features Brings together remote sensing, environmental, and computer scientists discussing their work from a psychological or human factors perspective Answers questions related to aesthetics of scientific visualization and mathematical analysis of perceptible objects Explains the perception and interpretation of realistic representations Provides illustrative real-world examples Shows how the features of display symbols, elements, and patterns have clear effects on processes of perception and visual search

Interpretation of Complex Images, Literature Survey


Book Description

This report is a review of the literature that might aid in measuring or describing complex images as stimuli, in relating this variable to the psychophysics of target identification, and in further specifying variables that may be important determinants of target identifiability. The body of this report is in four sections: (1) abstracts of articles containing general perceptual material, especially theories of form recognition or target identification; (2) abstracts of articles concerned with the experimental manipulation of perceptual variables known to be important determiners of form recognition and target identification; (3) articles concerned with measuring, changing, or simulating image parameters in some specified manner; and (4) abstracts of articles on the special characteristics of various sensor systems that will affect the resulting images used by the operator.




Exploratory Study in Interpretation of Vertical and High Oblique Photographs


Book Description

The study set out to determine the relative utility of vertical and oblique views and to define the conditions under which each is more effective. Interpreter performance in extracting information from vertical and oblique views was compared. Sixty-four experienced interpreters, divided into two groups of 32 each, interpreted vertical and oblique views of a common area. Two sets of photographs were used, one of an airfield, the other of a bridge. Performance comparisons for the airfield photos were for common areas constituting the foreground, background, and total area. For the bridge, only the total overlapping area was used. Comparisons were made separately for detection and identification, counting of objects, and mensuration. Vertical photos were found to be better for identification of objects with major dimensions in the horizontal plane, oblique photos for objects with major dimensions in the vertical plane. Mensuration was much easier on vertical photos than on oblique photos. In oblique viewing, completeness of interpretation, but not accuracy, was affected by the portion of the photo being interpreted. For the foreground, completeness was 28.5%, for the background 8.8%.
