the platform has a certain foresight, fully considering the feasibility of system upgrade, expansion, expansion and maintenance, and how to greatly improve the response speed of business processing.strong coupling between functions is avoided, computing service, data service, rendering service and interactive interface code space are relatively independent, and users can selectively pre-install different types of services.considering that most scenarios are non-network or weak network environments, data download and update functions are provided in online environments, and local data access functions are provided in offline environments.

the platform fully considers the relationship between the systems and focuses on the organic integration of various information resources. it considers both confidentiality and a certain degree of openness, and grasps the balance between information sharing and information security. the core layer provides general capabilities that do not involve specific business scenarios, such as positioning, base map rendering, coordinate conversion, spatial calculation, visibility analysis, path planning, etc.
