For large-scale airport construction projects, whether in the construction process or after the construction is completed, entering the Operation and Maintenance stage, a large amount of information and materials must be generated and used, including project process management and control documents, engineering drawings, workbooks, engineering technical documents, various images, and video information. These project construction-related information is called "Project content". It features a large amount of data and many data formats.

Therefore, a large amount of engineering content (management and technical information related to project process control, survey, planning, design, implementation, and completion) is generated throughout the entire project process) scientific management enables archive storage, data retrieval, application development, technical engineering utilization, operation and maintenance, and operation management to provide basic data and value-added application development, that is, the project content results must be collected, stored, played back, and processed.

Through the project content management platform established during the airport construction phase, the Geographic Information System of the Airport Project can store and manage the project images throughout the airport construction process. At the same time, based on the engineering drawings of the airport construction project, the basic geographic information database and geographic information management platform are built to provide data and platform support for the visualization application in the airport construction and maintenance process, on this basis, various visualization applications of airport construction and management are constructed.

Overall system architecture

The Geographic Information System of the Airport Project is an information system developed and built by combining the project content management and Geographic Information System. The overall logical framework of the system is illustrated in the following figure. It consists of the following parts:

2 base databases + 1 sharing and Service Platform + N applications

1. Engineering Geographic Information Database

Contains all the data stored by the system, including the electronic map database, underground pipe network database, Building Database, engineering cataloguing database, engineering file database, multimedia database, contingency plan database, real-time and historical dynamic information database covering the airport.

2. Geographic Information Data database creation and management platform

The Data Administrator of the entire system is responsible for transforming, integrating, storing, optimizing performance, and managing all geographic information data. This includes engineering data conversion, data standardization, data database creation, and data management. The C/S structure is used.

3. project data database creation and management platform

This service allows you to catalog, archive, import, secure, and version data of all process project documents. Including project data collection, project data cataloguing, project data database creation, and project data management. The main structure is C/S, supplemented by B/S structure.

4. Real-time information access platform

Implement Message Communication with multiple real-time technology systems, and connect various real-time information to the system. Message Service middleware is used. The real-time access information can be GPS, aodb, SMS, ground radar, and other information.

5. Project Geographic Information Sharing and Service Platform

Provides unified system integration interfaces, layer sharing, service systems, and map service interfaces for different applications to provide various support for business GIS applications.

6. Engineering Geographic Information Application Service System

It provides a wide range of business GIS application functions for different business units and is a portal for system display. It includes various applications, such as electronic atlas, GIS graphical applications for Emergency Command, and GPS Vehicle Tracking Management.

7. system users

Platform management users mainly implement system monitoring, user management, and daily maintenance for the platform. A single administrator can manage multiple platform management users. Different users have different permissions to obtain different information and functions.

8. System Security Protection System

Necessary means to ensure the daily operation of the system, including network layer protection.

9. System Security Management System

Measures to ensure the normal operation and reliability of the system, including users, permissions, performance, logs, monitoring, backup, and recovery.

10. Standard and Standard System

Ensure the effective integration and unification of system data, including data standards, technical standards and management standards.
