Terraced vineyard vigour mapping
Multispectral mapping of steep terraced vineyards, where ground scouting is slow and satellite data is too coarse.

The challenge
Steep schist terraces make walking the vines slow, and 10 m satellite pixels blur the vine rows into the walls between them.
What we did
We flew terrain-following multispectral missions and used a photogrammetric DSM to separate canopy from terrace walls before computing vegetation indices.
Outcome
The viticulture team now targets canopy management and irrigation terrace by terrace.
