Abstract: The comprehensive observation integration platform for natural resource elements is the assemble of network operation and management, the collection, transmission, preservation, mining, sharing of the observed data, and the mature achievements, which is the core of observation station network. The overall framework, management system, characteristics and advantages have been analyzed in this paper to introduce the construction situation of the comprehensive observation platform. The construction practice of the comprehensive observation integration platform is expounded through data integration, multi-source data fusion and model loading application, combined with the ongoing project. Finally, the focus, direction and technical application of the future work about the comprebensive observation integration platform are forecasted.
