Domestic Application Of High Spatial Resolution Image In The Geological Interpretation

Nature of geological structure and occurrence of all kinds of underground mineralresources, the earth’s surface are subjected to different degrees in the long-term geologicalforces. It can form a certain surface geological characteristic, and is closely related to thephysical geography, through satellite remote sensing image can be obtained the surfacefeatures information. High spatial resolution image due to its features clear characteristics, sohas a good visual interpretation. This article as a domestic high imaging application ingeological interpretation, according to the "based on3d geological interpretation abilityevaluation" project. Through the combination of geographic information technology and RStechnology, establish a processing platform, can be to improving the working efficiency andaccuracy.This paper by ENVI software for data processing platform, the original image datapreprocessing, frequency domain filtering and digital image processing techniques such asprincipal components transformation, strengthen geological interpretation information, at thesame time to the same regional DEM date for slope analysis, landscape rendering, such asprocessing, and integrated geological landform data extraction structure information. Fieldsample rocks spectral databases, spectral Angle (SAM) technique is utilized to extract thelimestone, sandstone, conglomerate3kinds of lithologic information, combined with fieldsurvey and geological data analysis, and interpretation confidence level is higher. Finally,using the ArcGIS software mapping function. mapping the research area of Integrated geologyinformation.
