The spectral data in existing object spectrum library have some disadvantages, such as single data acquisition sensor; unreasonable ground objects classification and no efficient integration of the latest spectral analysis models. In order to solve these problems, this paper proposes a typical target ground spectral information system. The ground spectral data acquisition, analysis, processing and integrated information extraction are designed and integrated, and the information expression of the system is constructed based on the client layer and the server layer (C/S) structure. Taking the extraction of rocks, mines, and heavy metals from soils as an example, the authors conducted a demonstration study. The research shows that the system has achieved the goal of efficient, fast and accurate excavation of the rich ground information contained in the spectra, thus providing technical support for land identification, resource exploration and ecological environment evaluation.
