SEN3GCP – Sentinel for 3D Ground Control Point

SEN3GCP is conceived as a service that will provide  GCPs (Ground Control Points) and precise co-registration of EO products as an automated service accessible via the web and API. The service will be based on a global database of GCPs that is derived from SAR imagery (3D coordinates including height information) and for which corresponding image chips of multispectral data are derived and maintained. The implemented service will provide GCPs via API and other interfaces. The service will also provide a mechanism for precise co-registration of EO data enabling for example the precise co-registration of multi-spectral and SAR data.
