【摘要】 我国典型地物标准波谱数据库是一个开放的定量遥感网络资源库 ,其子库地面观测波谱库收录的几种典型地物的地面观测波谱及配套元数据多达万余套。波谱数据及其元数据是研究和发展定量遥感的基础 ,其整合形式也因而成为整个波谱库的重中之重。本文借鉴波谱元数据的分类成果、利用知识的框架表示方法 ,提出了以文本文件为主的波谱数据三层文件体系表示 ,实现了波谱与波谱、波谱与元数据这两个维度的配套。针对这套波谱数据文件 ,对应其框架表示 ,文中采用查找表方法、设计并实现了数据的格式检查与程序定级更多还原

【Abstract】 The spectrum library is an open network database. As a critical part it contained the measured spectral database, which is intended to collect over 10,000 pieces of measured spectra and their metadata. As basic data of quantitative remote sensing, the integration mode of measured spectral data and their metadata is of great significance. On the basis of metadata classification and frame representation, this paper presented a three-level representation mainly of text files, which realized two kinds of composition between spectrum and spectrum and between spectrum and its metadata. Furthermore, Aiming at this sort of data format, we designed and realized the format-checking and grading of spectral data based on look-up tables.更多还原
