Abstract: Geospatial data constitutes a critical strategic resource and an emerging factor of production. This data encompasses geographic entities about the entire Earth’s surface, capturing detailed features and properties. Through coordinate systems, it achieves precise spatial positioning while revealing dynamic temporal variations. Since it integrates extensive spatial coverage with rich attribute records, this data often reaches large volumes. Existing access control models and mechanisms, however, struggle to regulate how this data is used as it circulates through governance and application scenes. To tackle these challenges in the complex network environment of the real-time intelligent service (PNTRC) network for cross-domain geospatial data, a Geospatial Data Circulation Control (GDCC) model and administrative model were developed, based on the Cyberspace Oriented Access Control (CoAC) model. It provides tailored implementation mechanisms for geospatial data circulation control in various scenes and formally defines and analyzes its functions and methods using Z language. Analysis and evaluation demonstrate that the proposed circulation control mechanism effectively ensures controlled transmission, usage and extended control throughout the entire lifecycle of cross-domain geospatial data circulation.
