The characteristics of the comprehensive observation data of natural resource elements are multiple sources, complex types and huge data volume. It is necessary to establish a comprehensive observation platform for natural resource elements (COPN) for the unified management and utilization of data. This article builds a comprehensive observation platform for natural resource elements (COPN) based on Internet of Things (IoT) and Open Data Processing Service (ODPS) technology, it mainly includes three modules: a natural resource element data center, an Internet of Things center, and a model cloud center. The platform enables the processes of data transmission, processing, and analysis from sensors to model clouds. The COPN serves the integrated management of natural resources across China and provides decision support for macro-control. The platform designed in this study will explore the design of various natural resource element related models and modularize them for scientific research and practical applications.
