Planimetricreferencelayers
Foundation
Airbus Optical Constellation
Geometric foundation created, maintained and updated by IGN through a co-edition agreement with Airbus since 2002:
GEO in-house reference databases: a long story with the French Mapping Agency (IGN)
Came from a need of French MoD for a global geometric reference frame (planimetric and altimetric)
Started with a co-financing Airbus- French MoD in the end of the 90s of a dedicated instrument on board of SPOT5 (HRS: High Resolution Stereoscopic) to acquire a global stereoscopic coverage used as the geometric frame up to now
Generation of the firstderived reference layer forthe MoD and Airbusover 80 Mkm²,between 2002-2014:Reference3D(ortho-mosaics + DEM)
![Page 8: Airbus Optical ConstellationAirbus...Planimetric reference layers Foundation Airbus Optical Constellation Geometric foundation created, maintained and updated by IGN through a co-edition](https://reader036.vdocuments.us/reader036/viewer/2022062303/6050f5a455cc245d503a7ed3/html5/thumbnails/8.jpg)
Planimetricreferencelayers
Coverage
Airbus Optical Constellation
GEO ground system (G/S): existing in-house reference databases
The HRS geometric foundation (space triangulation) gives the frame to generate ortho-mosaics layers used as planimetric references by GEO. Different mosaics done at different times with different sensors :
SPOT5 HRS: Reference3D (2002-2014)
SPOT5 HRG: PAS (2014-2015)
SPOT6/7: PAS Lama (2016-2018)
Altimetric references:
Reference3D DSM generated by IGN over 80 Mkm²: DTED2, accuracy <10 m LE90
SRTM over other areas
Integrated in GEO G/S facilities:
MOC, DRS
