Building an Airport 3D Data Base with High Accuracy

Background:Cairo International Airport (CAI), with ICAO code HECA, is a major international airport serving Cairo, Egypt. To ensure safe and efficient operations, an accurate Airport Mapping Database (AMDB) is essential. This case study focuses on the challenges faced during the creation of an AMDB for Cairo Airport, specifically the difficulties in surveying ground control points within the airport's operational zone and the integration of 3D scanning data into the database.

Key Stakeholders:

• Cairo Airport Authority

• Surveying and Mapping Teams

• Remote Sensing Specialists

• 3D Scanning Experts

• Airport Operations and Safety Teams

Use Case Steps:

1. Define Project Scope and Objectives:

• The Cairo Airport Authority initiates a project to create an accurate AMDB for Cairo Airport (HECA) for improved safety and navigation.

2. Data Collection Planning:

• The project team assesses the scope and data requirements.

• Remote sensing procedures are chosen to collect aerial imagery and topographic data.

3. Remote Sensing Data Collection:

• Aerial imagery, LiDAR, and satellite data are collected over the entire airport area.

• The challenge arises in surveying ground control points within the airport operational zone due to security and operational constraints.

4. 3D Scanning:

• 3D scanners are used to capture detailed geometric data of key infrastructure, runways, taxiways, and facilities within the airport.

• Scanning is conducted at various points throughout the aerodrome to capture a comprehensive 3D model.

5. Data Integration:

• Remote sensing data, 3D scanning data, and other available sources of information are triangulated to create a unified and comprehensive AMDB.

6. Ground Control Point Surveying:

• Specialized ground control teams work in collaboration with airport authorities to survey ground control points.

• Surveys are conducted during scheduled maintenance periods and with minimal disruption to airport operations.

7. Data Processing and Quality Control:

• Collected data is processed, and quality control checks are performed to ensure accuracy.

8. AMDB Generation:

• The integrated data is used to generate the AMDB for Cairo Airport, including detailed information on runways, taxiways, navigational aids, obstacles, and infrastructure.

9. Data Update and Maintenance:

• Establish a process for regular updates to the AMDB to keep it current and accurate.

• Implement a system for incorporating changes and modifications made to the airport's layout and facilities.

10. Usage and Benefits:

• The AMDB is made accessible to air traffic controllers, pilots, and various airport stakeholders.

• Improved safety, efficiency, and navigation within the airport operations lead to enhanced flight operations and passenger experiences.

Conclusion:Creating an accurate AMDB for Cairo Airport (HECA) involves the integration of various data sources, including remote sensing data and 3D scanning. Overcoming the challenge of surveying ground control points within the airport's operational zone requires close collaboration between surveying teams and airport authorities. The resulting AMDB benefits airport operations, safety, and overall efficiency, making Cairo Airport a safer and more reliable international hub.
