Services: Aerial + Terrestrial Documentation

Union Drones provides high-accuracy aerial and terrestrial documentation to support architects, engineers, environmental specialists, and construction teams. Our deliverables integrate cleanly with AEC workflows and align to GNSS control for reliable, repeatable results.

Aerial (UAS) Documentation

High-accuracy aerial mapping, photogrammetry, and visual documentation aligned to GNSS control for reliable, repeatable outputs.

Terrestrial Documentation

High-resolution architectural, structural, and site-level documentation using controlled capture methods and GNSS-based alignment.

Mapping & Site Documentation

  • Orthomosaic site imagery (coordinate-aligned)

  • DSM / DTM / CHM generation and elevation model exports

  • 2D annotated plan views for site logistics, phasing, and progress reporting

  • Topographic-style contours (reference only; not a legal survey)

  • Volumetric stockpile measurements (cut/fill estimates)

Building & Structural Documentation

  • Visual as-built documentation (exteriors + interiors)

  • High-resolution building envelope imaging

  • Roofing condition photography (shingles, membranes, flashing)

  • Thermal imaging for envelope leaks, insulation gaps, and roof moisture

  • Radiometric thermal outputs (TIFF + CSV data)

Construction & Progress Monitoring

  • Progress photo sets with consistent GNSS-aligned flight paths

  • Weekly/bi-weekly construction progress documentation

  • Accuracy-checked aerial captures using GNSS control points

  • Annotated progress summaries for PMs, architects, and owners

Architectural + Engineering Documentation

  • Detail-rich architectural and MEP focus shots for RFIs and field verification

  • Condition documentation for façades, interiors, and equipment rooms

  • Verification photos of installed doors, windows, fixtures, and mechanical equipment matched against project schedules

  • Closeout documentation packages

Ground Photography + Controlled Sets

  • High-resolution ground photography

  • Controlled-height, repeatable camera stations

  • Exterior elevation-matched photography for design teams

  • Ground-level visual as-builts for civil and structural projects

  • 360° panoramas and walkthrough captures for interior and exterior spaces

GNSS-Controlled Data Capture

  • Placement of GNSS control and check points

  • GNSS-ground control to unify aerial + ground deliverables

  • Check-point verification photography
