A Preliminary Exploration of Methods to Enhance Remote Sensing Lithology with Worldview-2 Data in Sedimentary Rocks Area——A Case Study in Kashi Altas District of Xinjiang

In order to further explore and discuss the application effects of Worldview-2 data in lithology identification, we chose Kashi Altas District in Xinjiang as our research area for Remote Sensing lithology enhancement study in this paper. Analyzing the measured spectrum curves of rocks and Worldview-2 data in the study area, we contrasted the spectral differences among different lithology. After comprehensively considering objects with the same spectrum and the shallow cover, integrating the band feature and data statistics properties of Worldview-2 data, we established a processing method, namely band combination-spectrum enhancement-decorrelation reinforce-texture information fusion. This method has effectively risen the contrast ratio among different lithology and greatly improved the external interference factors on the spectral information. In addition, it has also provided a reliable basis for accurately identifying the different lithology.
