Trimble GNSS receivers on heavy-duty tripods performing static benchmark measurements. Infrastructure Benchmark

National Geodetic Control & Infrastructure Cadastral Survey

  1. The Challenge

    Establishing reliable geodetic baselines across expansive, rugged terrain with intermittent cellular coverage — the kind of ground truth road construction and legal cadastre depend on.

  2. The Solution

    Multi-frequency Trimble R12i GNSS receivers running long-session dual-frequency static observations, tied to the International GNSS Service (IGS) reference frame and processed in Trimble Business Center (TBC) with least-squares network adjustments.

  3. What This Delivers

    High-accuracy control points suitable as the spatial foundation for engineering-grade infrastructure design and legal parcel cadastre.

Aerial survey crew setting up a drone at a commercial aggregate quarry. Autonomous LiDAR Mapping

Aerial Drone Photogrammetry & Quarry Volumetric Auditing

  1. The Challenge

    Manual aggregate inventory reconciliation traditionally means surveyors climbing hazardous rock stockpiles with GNSS poles — slow, and a real safety risk.

  2. The Solution

    A DJI Matrice 350 RTK drone with a Zenmuse L2 LiDAR sensor flies automated terrain-following lines. Point clouds are classified in DJI Terra and cut/fill volumes calculated in Carlson Mining.

  3. What This Delivers

    Faster survey turnaround with no personnel exposed to unstable stockpile terrain, and volumetric outputs suitable for inventory reconciliation and audit reporting.

Agricultural drone demonstration over a commercial sugarcane estate. Multispectral NDVI Optimization

Multispectral Drone Imagery for Precision Crop Health Optimization

  1. The Challenge

    Commercial sugarcane plantations applying uniform blanket fertilizer treatment risk over-fertilizing fertile sectors while under-treating compromised blocks.

  2. The Solution

    High-resolution multispectral drone flights generate Normalized Difference Vegetation Index (NDVI) analytics in ArcGIS Pro, producing prescription variable-rate application maps by block.

  3. What This Delivers

    Targeted, data-driven fertilizer application in place of blanket treatment — reducing input waste and supporting healthier, more consistent crop stands.

Phirez survey team with GNSS rover on a civil infrastructure corridor. Corridor Stakeout & As‑Built

Highway Corridor Stakeout & As‑Built Verification

  1. The Challenge

    Contractors need to stake out centerline alignment points quickly while verifying earthwork layers against tight design tolerances to avoid costly rework.

  2. The Solution

    Trimble S-Series robotic total stations paired with Trimble TSC7 controllers running the Trimble Access Roading module, allowing one-person operation directly from CAD alignment files.

  3. What This Delivers

    Faster daily stakeout with one-person operation, and as-built verification data that supports compliance sign-off against design tolerances.

US Radar GPR Rover ground penetrating radar cart with a GNSS antenna on a pole. Subsurface Asset Mapping

Subsurface Utility Line Tracing & Fiber Optic Strike Prevention

  1. The Challenge

    Expanding urban roads without reliable historical as-built drawings risks severing live power cables, pressurized water mains, and optical fiber lines during excavation.

  2. The Solution

    US Radar ground penetrating radar (GPR) coupled with Trimble Catalyst GNSS. Radargram cross-sections are converted into georeferenced 3D utility vectors.

  3. What This Delivers

    Georeferenced utility maps that reduce excavation risk and integrate directly into municipal spatial data infrastructure for future maintenance planning.
