Our GCP Measurement Services

KPGeo plans, measures, documents and delivers Ground Control Points and independent check points (ICPs) worldwide — available on demand or directly from an extensive global archive — providing photogrammetric control for satellite imagery triangulation, aerial triangulation, orthophoto georeferencing and UAV/drone mapping, at centimeter-level positional accuracy.

Every location

We collect GCPs almost anywhere on Earth.

Every point is quality-controlled before delivery.

  • ISO 9001:2015 & AQAP 2110 certified
  • Verified survey standard & structure
  • Identifiable on the imagery

Technology

Professional GNSS receivers and high-precision positioning methods deliver survey-grade geodetic control points.

  • Multi-constellation receivers
  • RTK, PPK, Static, Rapid Static & PPP
  • Centimeter-level horizontal and vertical accuracy

Over a Decade of Global GCP Surveying

Since our first survey in 2011, KPGeo has built one of the world’s largest commercial GCP archives — 8,500+ Ground Control Points at 700+ locations across 130+ countries and all six inhabited continents, from Arctic Norway and Greenland to southern Chile.

We never lose sight of what is at stake: the accuracy of an entire photogrammetric project — orthophotos, DSMs, 3D models and every derived measurement — is only ever as good as its Ground Control Points. That is why rigorous quality control is built into every step of our work, not bolted on at the end.

Applications

From energy to aviation, our Ground Control Points make imagery measurably accurate across every industry — for satellite, aerial and UAV/drone mapping.

Aviation & Aerodromes

Airport control for AMDB, eTOD and orthophoto — 700+ airports surveyed.

Solar & Renewables

Georeferenced control for PV plant design, grading and as-built verification.

UAV / Drone Mapping

High-accuracy GCP for UAV/drone mapping — control and check points for drone orthomosaics and DSMs.

Infrastructure & Corridors

Consistent positioning for roads, rail, pipelines and power lines.
