基于VB和SQL Server的典型地物光谱数据库系统的设计与创建

不同的地物具有不同的波谱特征,这已成为人们利用高光谱遥感数据认识和识别地物、提取地表信息的主要思想和手段。收集和积累各种典型地物的光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。本文简单介绍了当前国际上常见的波谱数据库并根据建立的一个光谱数据库管理系统探讨了该系统的组成与功能、光谱数据库建立的数据要求、创建数据库的过程及接口设计等关键问题,为之后的光谱匹配研究奠定了基础。

The Design and Building of the Spectrum Database for the Typical Ground Objects Based on VB and SQL Server

It becomes the main idea and method to gain the surface information of the earth and understand and recognize the ground objects by using the spectral remote sensing data because different ground objects have different spectrum.Meanwhile,collecting and accumulating all kinds of typical spectrum data is a very important aspect for basic study and application in remote sensing.The paper involves several key problems,it simply introduces some familiar spectrum databases in current,and discusses the structure and function of the system,the requests of the data for database building,the progress of the database building and the interface designing.All those have laid the foundation for the study of the spectral matching.
