THE FRAME DESIGN AND APPLICATION DEMONSTRATION OF THE STANDARDIZED SPECTRAL LIBRARY FOR FEATURED CROPS IN GUANGDONG PROVINCE

Internationally,the building of the standardized spectral library in remote sensing has already developed towards network share since 1990's. As a reform and opening window in China, Guangdong province urgently needs building up a standardized crop spectral library, especially in featured crops of South China, for stepping up the agricultural information level. This research focused on the organization of spectral data and the construction of a database system for featured crops of Guangdong province. The database is composed of five parts, i.e., the knowledge database, the library for measured spectra, the remote sensing model database, the spectral analysis and the application demonstration for the litchi orchard. In the spectral analysis, the authors designed and provided the query of spectral data, the uploading of remote sensing images, and the analysis and simulation of spectral data. The spectra-based planting area monitoring demonstration of the litchi orchard is presented so that the users can utilize the spectral library conveniently.
