摘要： This paper studies the interpretation of the cropping area of winter wheat in Henan Province with 3S technology. The technical route, the selection of the image, the forehand processing of the image, the setup of the interpretation indications and the selection of interpretation method are discussed. The TM images during the period from the latter November to next January are chosen as the main remote sensing information resources. Through complete and reliable interpretation indications, the efficiency and precision of interpretation is satisfied under the environment of ARC/INFO and ERDAS by the method of interactive image interpretation system. The phenomena of "same thing different characteristic and different thing same characteristic" and the ways to deal with the phenomena are also discussed.
