Mapping large, rugged areas of land like those in Makkah has traditionally been a slow and labor-intensive process. When dealing with several square kilometers of uneven terrain, manual ground teams often spend weeks or even months walking the site to collect enough data points. In the recent project taking place in Makkah, the goal was to survey a total area of 3.75 km2 to provide the foundation for a new real estate development by Nakheel. To meet the project’s tight deadlines, the team moved away from traditional methods and turned to the sky.
High-Tech in the Sky
The secret to the project’s speed was the use of the DJI M350 RTK drone equipped with the Zenmuse L2 laser scanner (LiDAR). Unlike a standard camera that just takes pictures, this system uses laser pulses to “see” the land in three dimensions.
- Precision Flights: The drone completed 18 separate missions at an altitude of 60 m to ensure every inch of the land was recorded.
- Laser Mapping: This technology is especially useful in Makkah’s rocky landscape because it can accurately measure the ground surface even when it is covered by rocks or light brush.
- Safety First: By flying overhead, the team avoided the risks and physical strain of sending ground crews into difficult or dangerous areas of the site.
Drones vs. Ground Methods
The most impressive part of this project was how much time was saved at every stage. When we look at the numbers, the efficiency of drone surveying becomes clear:
- Aerial Speed: The entire 3.75 km2 area was scanned from the air in just one day.
- Ground Support: 2 days were needed to set up ground markers to ensure the map was perfectly accurate.
- Fast Processing: It took just four days for the office team to turn the millions of laser points into a finished 3D model.
- The Results: While traditional ground methods could have taken weeks for a site of this size, the entire project was delivered in only 9 days.
Ready for the Next Move?
By using drones, the project didn’t just finish faster, it provided better data for the engineers and architects. The final maps had a high resolution of 3 cm/pixel and included detailed contour lines spaced every 1 meter. This meant that our client could start their planning and construction work weeks ahead of schedule.
