【摘要】 自然界中的地质构造及其赋存的各类地下矿产资源，在地表均不同程度地遭受到长期的外力地质作用。这样就会形成一定的地表地质特征，并且与自然地理密切相关，通过卫星遥感图像可直接或者间接得到这些地表特征信息。高空间分辨率影像由于其地物特征表现清晰，所以具有良好的目视解译优势。本文作为国产高分影像在地质解译中的应用，依据“基于三维的地质解译能力评价”课题，以凤翔至灵台一带为研究区，对构造信息及岩性信息进行地质解译。通过地理信息技术和遥感技术的结合，建立规范有效的信息处理平台，可以一定程度上提高传统地质行业的工作效率和地质现象识别精度。本论文以ENVI软件为数据处理平台，对原始影像数据进行预处理、频率域滤波及主成分变换等数字图像处理技术，增强地质解译信息，同时对同一区域DEM数据进行坡度分析、地貌渲染等处理，然后综合地质地貌资料提取构造信息。建立野外样本岩石光谱数据库，利用光谱角(SAM)技术提取了灰岩、砂岩、砾岩三种岩性信息，结合实地勘测和地质资料分析，解译置信度较高。最后利用ArcGIS软件的制图功能，绘制研究区内的地质信息综合解译图。更多还原

【Abstract】 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.更多还原
