摘　　要：本文从当前遥感解译工作存在着“同物异谱”和“同谱异物”等问题出发,提出建立光谱知识库,着重开展典型地物选取以及数据库设计等研究,分析典型地物特征以及采集周期,设计典型地物分类编码,开展光谱知识库概念、逻辑、物理等结构设计,形成以地物光谱实测子库、遥感影像样本子库、遥感信息子库、元数据子库组成的光谱知识库,为今后光谱数据采集、处理、检查、入库等工作提供依据,为测绘工作中“数据获取实时化、数据生产智能化”的目标提供技术支撑。From the problems of“the same spectrum and different spectrum”and“the same spectrum and foreign matter”in remote sensing interpretation,this paper proposes to establish a spectral knowledge base,and focus on the research of typical ground object selection and database design,analyzes the characteristics and collection cycle of typical ground objects,design classification code of typical features,carry out the structural design of spectral database concept,logic,physics and so on,so as to improve the work of spectral data collection,processing,inspection and storage in the future,provide technical support for the goal of“real-time data acquisition and intelligent data production”in surveying and mapping work.
