The design and realization of web-based remote sensing model library

In this paper, we proposed the construction of a spectral knowledge library, which is composed of observed data library, image library, prior knowledge library and remote sensing model library. We stated the status and functions of remote sensing model library in the whole library, and discussed its structure, system architecture and development technique under network environment We also discussed remote sensing model library's driving mechanism under the support of spectral knowledge library and meta data.
