组件式GIS在典型地物波谱特性数据库中的应用

由于各种地物的结构和成分不同，它们的波谱反射特性也不同，其波谱特性数据是遥感定量分析和计算机智能提取地物类型的基础数据，是地物识别的重要依据。收集和积累各种典型地物的波谱数据信息历来是遥感基础研究和应用中不可缺少的一个重要环节。采用组件式GIS的思想，将采集到的西安地区典型地物波谱数据与矢量化后的地图绑定，通过建立地理信息数据库，实现了典型地物波谱数据的显示，查询，分析，管理等功能，在小型区域研究、高光谱分辨率遥感信息处理、地物识别原理研究和高光谱专题研究起到一定作用．

The Application of Com-GIS in the Spectral Database System for the Typical Ground Objects

Computer intelligent has the extraction of the ground objects features, meanwhile, it is an important basis for features＇ identification. Collection and accumulation of various typical features of the spectral data information has always been a basic research and application of remote sensing indispensable as an important aspect. In this paper, the idea of component-based GIS will be collected in Xi＇an area of spectral data and map binding. Through the establishment of geographical information database, the implementation of the typical spectral features of data display, query, management and other functions have been come true. It played an important role in the future hyperspectral remote sensing information processing, the research of the mechanism of features to identify and hyperspectral feature research.
