I need a licensed land-surveyor to lay out and accurately survey a network of ground control points across a rural site that covers roughly one to five square kilometres. The data will underpin an upcoming aerial survey I’m running for construction planning, so sub-centimetre positional accuracy is mandatory. You will be responsible for: • Selecting safe, clearly visible point locations that give even coverage of the terrain • Marking each point with durable targets suitable for fixed-wing and multirotor captures • Surveying every target with RTK GNSS or an equivalent high-precision method, then supplying a coordinate file in both WGS84 and local grid I will consider the job complete once I can import your coordinates, check them against a couple of redundant check points, and see consistent residuals under 3 cm in my photogrammetry software. The site is accessible by 4×4 and daylight hours are flexible. If you already have recent rural-site experience and can mobilise quickly, let’s talk dates and any permits you might need.

I am Rashidab, I am ready to start work right now. I can support the planning and documentation for your ground control point survey by preparing a clear layout strategy for evenly distributed targets across the site and defining visibility and safety considerations for aerial capture. I will organize the coordinate data structure, quality checks, and deliver clean files in WGS84 and local grid formats so they integrate smoothly with your photogrammetry workflow and validation process.

✅✅✅Expert here✅✅✅ I’m a licensed land surveyor with recent rural-site control experience and can mobilise quickly. For your 1–5 km² site, I will: • Plan a well-distributed GCP network to ensure strong geometry and safe, visible locations • Install durable, high-contrast targets suitable for fixed-wing and multirotor imagery • Survey all points using dual-frequency RTK/PPK GNSS tied to verified benchmarks • Deliver adjusted coordinates in WGS84 and the required local grid, plus a control report with residuals and redundancy checks My workflows routinely achieve sub-centimetre precision, and I understand the importance of <3 cm residuals in photogrammetry QA. I have 4×4 access capability and flexible scheduling. Happy to confirm datum requirements, number of GCPs/check points, and any permit needs so we can lock in dates.
