In total, eCognition delineated 27 classes. Exporting the
classifications as shapefiles, the 1:25,000 map of the PNRA
was finalized in ArcGIS.
Based on that mapping success, CBN received regional buy-
in to scale the mapping system for the whole of Brittany.
BRITTANY, BY NATURE
Similar to the PNRA project, the landscapes of each of
Brittany's four departments — Finistère, Ille-et-Vilaine,
Côtes-d'Armor and Morbihan — would be categorized into
27 major classes and mapped at a 1:25,000 scale.
In March 2018, the team began with Finistère in the
extreme west of Brittany.
Following the same previous approach, they acquired and
created color orthomosaics and integrated ancillary data.
Using customized rule sets, eCognition sorted all of the
Wet heathlands, one of the most difficult vegetation types to
automatically classify. Photo credit: Oriana Garcia.
