Ground Control Points


Highly accurate 3D coordinates – up to centimeter level!


Ground Control Points are essential for accurate ortho-rectification of aerial, optical satellite imageries and drone data, for precise localization of ground features and landmarks detection. Furthermore Ground Control Points calibrate and validate all kind of maps (topographic, HD maps) and increases the accuracy of Geo Data.

Fully independent of weather conditions and daylight the Ground Control Points can be extracted anywhere on Earth at any time.

Assets of Ground Control Points:

  • Essential for precise ortho-rectification of optical imagery, Elevation Models and Maps

  • Validate & Calibrate mobile mapping data & HD maps for autonomous driving vehicles

  • Precise Geo- Information Layer for Mapping (Map scales 1.2,500 – 1.10,000)

  • Runway accuracy determination for aircraft landing safety

  • Precise localization of ground features for mission planning

Ground Control Points key features:

  • Accuracies up to 10 cm horizontal/vertical

  • Covering large areas (1000 km²) per product

  • Complementing in-situ measurements

  • 10 to 20 Ground Control Points to choose per product

  • ESRI shape file and Google KML file with the exact point location information

Your Advantages with Ground Control Points:

  • High location accuracy to centimeter level

  • Fast data collection processing and delivery

  • Globally available as homogenous data source

  • Intensive cost & time saving compared to in-situ measurements


  • Mapping: Precise orthorectification of input data, supporting map scales of 1:2,500 to 1:10,000

  • Aeronautics: Build and refresh airport runway database

  • Defence: Support of mission planning

  • Oil, Gas and Mining: Localisation of potential exploration sites and pipeline corridors

  • Civil Engineering: Infrastructure planning

  • Automobile Industry: Co-registration and validation of HD maps and mobile mapping data to support autonomous driving
