Research On Magmatic Rock Interpretation Method Based On WorldView-2 Data

Papers "West Kunlun metallogenic belt Mineral Resources Remote Sensing Geological Survey projects as the basis to carry out the WorldView-2 data in the magmatic rock lithology interpretation method.In-depth analysis of the characteristics of the WorldView-2 data basis,to carry out the analysis of data preprocessing methods of research and common magmatic rock lithology information enhancement method,and to do research for the interpretation of the different types of igneous rocks and the magmatic rock lithology interpretation of case studies in the area north of race Tula.The main results achieved are as follows:(1)On the basis of in-depth analysis of WorldView-2 data characteristics to determine the WorldView-2 data preprocessing methods,including:FLAASH atmospheric correction method,based on the rational function model and IRS-p5 DEM's Orthorectification method,and Pansharp fusion methods.(2)To carry out the WorldView-2 data band combination,stretching method,the ratio of enhanced HLS transform high-pass filter for magmatic rocks lithology enhancement method achieved good enhancement.(3)Based on different magmatic rock lithology information enhancement methods for different types of igneous rocks(granite,mafic ultramafic rock,dykes)conducted a study of the lithology interpretation system.(4)On the basis of the above method,to the north the area of Saitula in west Kunlun as an example,combined with regional geological setting of magmatic rock lithology interpreted to identify the distribution of igneous rocks in the region,and achieved good application effect.
