The “Physiognomic mapping of natural vegetation” Scientific Expertise Centre (SEC) brings together teams from UMR TETIS that develop Physiognomic mapping of natural and semi-natural vegetation (structure, density, biomass) to meet the needs of managers of natural environments and those of stakeholders in green and blue infrastructures.

The product resulting from the Physiognomic mapping of natural vegetation SEC has a resolution of 1/25000 and covers the national territory.

The data used are multi-year high spatial resolution images series (Landsat 8 and/or Sentinel 2) and very high spatial resolution images from spring (IRC and/or SPOT 6-7 orthophotographs).

A processing chain version and a methodology guide have been available since 2017 through the PHYMOBAT tool for physiognomic mapping of low-altitude open environments by remote sensing.
