福建省ETM卫星遥感数据预处理方法

Preprocessing remote sensing information source of Fujian Province

为了更好地查明地方福建省土地资源利用的基本情况,本研究应用现代遥感数据处理技术,通过对2000~2001年的Landsat ETM遥感数据进行数字镶嵌,几何精校正、增强处理以及假彩色合成等预处理,同时结合各种现势资料,达到突出影像有用信息,压制干扰信息,提高图像的可解程度,提高解译效果的目的。并对其进行影像质量分析,效果良好,可作为本课题后续地理底图编制和地理底图数据库建库的数据基础。

Application of modern remote sensing data handling technology, processing and integrating of existing data, in order to fully tap the potential of information and improve the comprehensive level of resources survey. Researching of remote sensing image processing method, highlighting the useful information, suppressing the interference information, drawing up the method of image making, in order to improve the image evaluation and the effect of interpretation.The project involves abundant survey field and a wide range of investigation, high requirement of remote sensing and geographical map. On the basis of fully analyzing the practicability and comprehensive, the national imagery and geographic base map production standards, diagram of the preparation of project based, so that the results of the project standardization and standardization.
