Airbus Space Reference Points (SRPs)

Best-in-Class 3D Reference Layer

SRPs are a global reference layer, consisting of a set of image chips, every 2km², with a 3D center coordinate.

The database is available almost everywhere across the world, supporting massive image and orthorectification processing and can register all kind of optical images, automatically with limited human interaction.

The SRP database is co-edited by the French mapping agency (Institut National de L’Information Géographique et Forestière, IGN) and Airbus.
