抄録

Airphotograph interpretation is useful and popular method in researching landslides. However, it is pointed out that the method lacks in objectivism due to difference in interpretation between individuals. Therefore, we have checked causes which bring about such difference, and investigated the problems of interpretation.<BR>Based on the results, we introduce the concept of probability and propose judging criteria for airphotographinterpretation in order to be more objective method. The probability is composed of three stages based on certainty of topographic features. And then, we make two inventory maps: landslide map showing topographic features htrough airphotographs, and landslide division map which is associated with interpretation and its criteria.<BR>Because that interpretation of airphotographs is more are less subjective, individual difference is inevitable. However, we conclude that the above method is more scientific and reproducible.
