The Information Service Platform refers to: using the " digital earth " theory, based on remote sensing,

Centralized management of existing massive spatial data

For existing massive spatial data (

The whole system is divided into four major subsystems: operation support subsystem , data management subsystem , spatial information resource sharing subsystem , and spatial information service subsystem.

Establish a unified basic spatial data sharing service platform to implement the storage, update, and maintenance management of image data, electronic map data, DEM data, picture data, and other (space-related) multimedia data based on open data structures, and Provide public data storage solutions based on large commercial spatial databases.

Achieving a unified visualized comprehensive basic spatial data sharing service platform display. Effectively integrate and fully display remote sensing image data, vector electronic map data, DEM data, and other multimedia data (related to spatial location), and realize basic data display of the basic spatial data sharing service platform.

Establish a unified basic spatial data sharing service platform sharing interface to provide data sharing services for municipal governments and commissions.
