| Abstract: | 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. |
