地形信息光谱数据库系统设计与开发

The design and development of topographic information spectral database system

地形信息光谱数据库以地形信息波谱数据的知识化、定量化和实用化为目标,是一个集地物光谱实测数据、环境参数、景观图片数据、影像数据、测绘知识等于一体的地形信息光谱知识库,具有数据转换、检索查询、可视化分析及光谱匹配等功能。地形信息光谱数据库实现了地物波谱数据与地形图中地形要素的有机结合,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,为快速实现地形图的测制与更新提供新的技术方案。

Aimed at knowledge, ration and practice of the spectral data on the terrain information, topographic information spectral database is a kind of knowledge library for objects that consists of spectrum data, environmental parameter data, aerial/space image data, as well as the survey knowledge. It includes data conversion, data search and query, visualized analysis and spectral matching, etc. Topographic information spectral database, which combines object spectral data and terrain features, provides us with technique support and experimental environment for automatic classification on terrain element attributes, and provides a new scheme for surveying and updating topographic map quickly.
