EVALUATION OF REMOTE SENSING IN CONTROL OF PINK BOLLWORM, IN COTTON TYPE Ⅲ, NO. 1

摘要

The main objective of this investigation is to evaluate the use of a satellite in monitoring the cotton production regulation program of the State of California as an aid in controlling pink bollworm infestation in the southern deserts of California. Color contained images of ERTS-1 multispectral images simulating color infrared are being used for crop identification. The status of each field (i.e., crop, bare, harvested, wet, plowed) is mapped from the imagery and is then compared to ground survey information taken at the time of ERTS-1 over flights. A computer analysis has been perforated to compare field and satellite data to a crop calendar. Correlation to date has been 97% for field condition. Actual crop identification varies;cotton identification is only 63% due to lack of full season coverage.
