Project Overview

2cofly conducted a 100-acre drone survey for Core Tech International, utilizing LiDAR and photogrammetry to capture highly accurate topographic data. This project aimed to support two key sites—one designated for a solar development project and the other for facility planning.

To optimize efficiency, 2cofly partnered with TG Engineering’s survey team to accelerate the data collection process, ensuring fast and accurate results while reducing the timeline of traditional surveying methods.

The Challenge

Surveying large-scale land areas manually is both time-consuming and resource-intensive. The engineering team required a fast, high-precision dataset to aid in surveying, planning, and development.

Given the size of the survey area and the need for precise elevation data, a drone-based LiDAR and photogrammetry approach was the ideal solution to:

• Capture high-resolution terrain data over a large footprint

• Reduce survey turnaround time compared to traditional ground methods

• Provide engineering-grade deliverables for planning and development

Approach & Methodology

Advanced Aerial Data Collection

2cofly deployed LiDAR-equipped drones to scan the terrain with centimeter-level accuracy, generating a high-density 3D point cloud. In parallel, high-resolution photogrammetry was conducted to produce an orthomosaic map, ensuring a detailed visual representation of the survey area.

Collaboration with TG Engineering

To enhance accuracy, TG Engineering’s survey team provided ground control points (GCPs), ensuring the drone-derived data was georeferenced to precise coordinates for engineering applications.

Deliverables Provided

• 3D Colorized Point Cloud – High-density data for detailed topographic analysis

• Digital Elevation Model (DEM) – Accurate representation of ground terrain

• 1’ Contour Map – Engineering-grade elevation contours for planning

• High-Resolution Orthomosaic Map – Detailed aerial imagery for land assessments

Results & Project Impact

Accelerated Survey Completion

Drone technology significantly reduced the time required for data collection, allowing engineers to move forward with surveying, site planning, and analysis faster than traditional methods.

Highly Accurate & Actionable Data

The combination of LiDAR and photogrammetry provided a detailed and accurate dataset, enabling engineers to make informed decisions regarding infrastructure planning, land grading, and facility design.

Improved Cost Efficiency

By leveraging drone-based surveying, Core Tech International saved time and resources while obtaining comprehensive and precise data, making the development process more efficient.

Conclusion

By integrating LiDAR and photogrammetry with traditional surveying methods, 2cofly and TG Engineering delivered a fast, accurate, and cost-effective mapping solution for Core Tech International. This project demonstrates the power of drone technology in large-scale site development by improving efficiency, accuracy, and planning capabilities.
