IIM DATA PROCESSING FLOW AND ITS GEOLOGICAL APPLICATION
摘要
Abstract
This paper evaluated the characteristics and discussed some problems of IIM 2C data. On the basis of an analysis, the solutions for the problems were provided and a data processing flow was established which can provide a method for future researchers. The results show that the response of the left side of IIM data is lower than that of the right in the space domain, and the response of the longer bands has larger errors in the spectral domain. The authors provided a feasible method for modifying these problems. The resulting reflectance derived from absolute calibration and radiometric distortion correction was matched well with earth-based spectra, which suggests that the modified data can be used to study the geology of the moon. With the modified IIM data this paper probed into the types of the rocks in the Aristarchus Plateau area. The results show that the rocks are diverse in this area in both vertical and horizontal directions. The classification accuracy was improved much after the correction for IIM 2C data. Moreover, the possible landslide on the west wall of the Aristarchus crater was recognized. This study indicates that after calibration and correction the IIM data can contribute to the lunar scientific research by exerting its advantages of high spatial and spectral resolution.关键词
