What is a UAV?
A UAV (Unmanned Aerial Vehicle) is an aircraft that flies without an onboard pilot — remotely controlled or following pre-programmed flight paths. In construction, UAVs carry cameras and sensors that capture site imagery for mapping, progress tracking, and inspection.
How It Works
A flight plan is programmed over the site → the UAV flies automated passes capturing overlapping images → imagery is processed with photogrammetry software into maps and 3D models → outputs are georeferenced with ground control points or RTK positioning.
Applications in Construction & AEC
- Automated site progress capture
- Orthophoto and topographic mapping
- Stockpile and earthwork volume measurement
- Roof, facade, and hard-to-reach inspections
- Marketing and stakeholder visuals
UAV vs. Ground-Based Capture
UAVs cover large areas quickly and reach places crews can’t, but resolution and interior access are limited. Ground-based capture (360° cameras, laser scanners) excels indoors and up close. Combined, they provide complete site coverage.
