3.1 · The comparison

Two orthophotos of the same front, thirteen months apart.

Move the line and see what the field campaigns measured - not a model, not a forecast, the same coastline photographed twice.

Methodology in brief: a nine-point passive geodetic network, drone photogrammetry, and a Kriging model selected on residuals. Full method in the publications below.

The science is open.

Partners support the mission. They never influence the data.

Science needs witnesses. And partners.
