光谱信息数据库系统设计与开发

尽管我国已建立了地物波谱数据库系统，但针对地形图测制与更新中地形要素属性信息分类提取的实用化波谱数据库系统还未见报道。以地形信息波谱数据的知识化、定量化和实用化为目标，利用ORACLE数据库和VC＋＋编程技术，研制开发了集地物光谱数据采集、数据转换、检索查询、可视化分析及包络线消除等功能于一体的实用化数据库系统，为地形要素属性信息自动分类提供了技术支撑和实验环境。

The Design and Development of Spectral Information Library

Although spectral libraries based on surface features have been built in our country,it is not still reported that the practical spectral library system aimed at the attributes information classification and extraction to the terrain element on survey and updating relief map.Targeting knowledge,ration and practice of the spectral data on the terrain information,by use of ORALCE database and VC programming technique,we design a database system which integrated data collecting,data conversion,search and query,visual analyzing and continuum removal,etc,and can provide us with technique support and experimental environment for automatic classification to terrain element attributes.
