【摘要】 首先,介绍了基于TM图像进行地质解译的理论、技术和方法,然后,根据TM图像光谱特征,确定了用于地质解译的最佳波段组合,采用主成份、比值等方法,设计了岩石矿物信息提取的方案;最后,通过目视解译、图像增强、光谱增强、统计分析等方法完成某场地地质解译,在解译过程中对每一种岩石矿物都利用多种方法解译,相互验证,有效的提高了解译精度。更多还原

【Abstract】 The paper introduced the theory,techniques and methods about geological interpretation based on TM imagery.According to the spectral characteristics of TM imagery,the Optimal Bands Composite on geological interpretation is given,the scheme of extracting information is designed by using the method of principal component analysis,ratio analysis and so on i At last,by visual interpretation,image enhancement, spectral enhancement,statistical analysis and other methods to complete geological interpretation of the one site,in the process of interpretation more than one methods are used to extracting geological information,the accuracy of interpretation is improved effectively.更多还原
