A map-guided approach to interpretation of remotely sensed imagery is described, with emphasis on applications involving continuous monitoring of predetermined ground sites. Geometric correspondence between a sensed image and a symbolic reference map is established in an initial stage of processing by adjusting parameters of a sensor model so that image features predicted from the map optimally match corresponding features extracted from the sensed image. Information in the map is then used to constrain where to look in an image and what to look for. With such constraints, previously intractable remotesensing tasks can become feasible, even easy, to automate.

Computerized imageprocessing represents a level of technology sufficiently advanced that the Agency for International Development (AID) has had years of problems attempting to set up the necessary equipment support. The theory of patternrecognition and various software algorithms, such as maximum likelihood, k th nearest neighbor, and supervised clustering, are difficult to teach to remotesensing resource managers and technicians with limited education in mathematics. Computer hardware is relatively complex and, in addition to requiring programming skills, both procedural level, as well as operating systems, also requires training in electronic ″trouble-shooting″ and computer maintenance to keep systems in operation.

A description is given of a multi-purpose image-processing system. This system was designed for different applications, for example, medical imageprocessing (thermographic imaging, computer assisted diagnosis, etc. . . ), remotesensing (multispectral analysis and classification, thermal mapping of rivers, etc. . . ) and electron microscope imageprocessing (T. E. M. , noise filtering, patternrecognition, geometrical measurements). The system can be connected on-line to any kind of input and output image-peripheral. The peripherals used now are: TV camera, thermographic camera, flying-spot scanner, flying-spot film recorder, mechanical scanner coupled to an optical processor, refreshed B&W and color display, graphic tablet, magnetic tape and disc.

A current NASA technology research program and a projected plan are described for developing adaptive sensing technology through a coordinated ground-based research effort and a Shuttle flight-experiments program. The first phase includes a Feature Identification and Location Experiment (FILE). Hardware is completed and the experiment is scheduled for flight on Shuttle (STS2/flight OSTA-1) in 1980. The experiment object is to evaluate a technique for autonomously classifying earth features into four categories: bare land;water;vegetation;and clouds, snow or ice. The FILE experiment is described and the evolution of the technology development plan from feature identification to autonomous pointing, tracking, and navigation functions is outlined.
