Port Survey for Military Infrastructure Development – Tinian, CNMI

Topographic survey of critical infrastructure

Client

NAVFAC & TG Engineers

Project Type

Topographic Mapping

Location

Tinian, CNMI

Project Overview

2cofly, in partnership with TG Engineers, conducted a comprehensive LiDAR and photogrammetry survey for the Naval Facilities Engineering Systems Command (NAVFAC) to support military infrastructure development at a strategic port in Tinian, CNMI. This survey was critical for planning construction, optimizing logistics, and ensuring site suitability for military operations.

Leveraging advanced drone technology, the entire aerial survey was completed in just three days, providing NAVFAC with high-resolution, engineering-grade data far faster and more efficiently than traditional surveying methods.

Approach & Methodology

Dual-Method Data Collection for Maximum Accuracy

✔ LiDAR Scanning for Detailed Elevation Data – Penetrated vegetation and mapped land and built structures with high-precision 3D modeling.

✔ Photogrammetry for High-Resolution Aerial Imagery – Captured detailed orthomosaic maps for visual site assessments.

Rapid & Efficient Drone Deployment

✔ Full 3-Day Data Collection – The entire survey was completed in just three days, drastically reducing time on-site and labor costs.

✔ Minimal Disruption to Military Operations – Drones allowed for fast, non-intrusive data collection, avoiding operational delays.

Collaboration with TG Engineers for Survey-Grade Accuracy

✔ Integration of Ground Control Points (GCPs) – Over strategically placed GCPs ensured high-precision georeferencing.

✔ Engineering-Ready Data Processing – The collected data was processed and delivered in formats suitable for NAVFAC’s construction planning.

Deliverables Provided

✔ High-Resolution Orthomosaic Maps – Georeferenced imagery providing detailed visual site representation.

✔ 3D LiDAR Point Cloud – A highly accurate dataset for engineering analysis.

✔ Digital Elevation Model (DEM) – Detailed topographic data for infrastructure planning.

✔ Structural & Terrain Mapping – Essential for port construction and logistics planning.

Results & Project Impact

✔ Faster & More Cost-Effective Surveying

Completing the full survey in just three days provided the engineering team with rapid access to high-quality engineering data, allowing for faster decision-making and project planning.

✔ Engineering-Grade Accuracy for Military Port Development

The combined LiDAR and photogrammetry dataset allowed NAVFAC engineers to:

Analyze terrain and structural conditions
Plan infrastructure upgrades and expansions
Optimize logistics for military port operations

✔ Efficient & Scalable Data for Future PlanningWith the high-resolution aerial data, NAVFAC can now reuse and integrate the dataset for future projects, assessments, and environmental impact studies.
