DGPS / Total Station / GPR Survey
Engineering-grade ground survey, control, and underground utility detection.
MapSphere provides high-precision ground survey using DGPS, RTK GNSS, Total Station, and GPR for positioning, control establishment, engineering layout, and underground utility detection.
Our field teams establish reliable control and capture survey-grade measurements for topographic, route, rail, cadastral, alignment, tunnel, and bridge projects.

DGPS / Total Station / GPR — common questions
01When do you use DGPS versus total station?
DGPS/RTK GNSS is ideal for open-sky control and topographic survey at ±1–3 cm; total stations give ±2–5 mm for precise layout, setting-out, and areas with poor satellite visibility. Most projects use both together.
02What can GPR detect underground?
Ground-penetrating radar locates buried utilities, pipes, cables, voids, and reinforcement non-destructively, supporting utility mapping and safe excavation planning.
03Do you establish project control?
Yes — we establish and verify primary and secondary control points on your chosen datum, providing the survey-grade framework that ties every downstream deliverable together.
