swissEO VHI: state of forest health

Description

Map of forest condition based on the VHI (Vegetation Health Index), which reflects the current state of forest in relation to the climate reference period 1991-2020. The index is based on satellite data (Meteosat, Landsat 5,7,8, and Sentinel-2) of different spatial resolutions, aggregated to a ten-meter resolution. The VHI consists of two components: one part (VCI - Vegetation Condition Index) represents the local biophysical conditions of the vegetation, and the other part (TCI - Thermal Condition Index) characterizes the climatic conditions (temperature). Both components depict the current situation in relation to a reference period. The combined VHI is used to assess drought and other disturbances or stress factors— the lower the value, the greater the stress and its impact on vegetation. The forest area is shown on the map, providing a robust indicator of the regional vegetation conditions. The dataset was developed in collaboration with MeteoSwiss for the federal drought portal. The data processing is still in the commission phase (set-up and validation) until the first quarter of 2025, so the data may be subject to change during this period. Contains modified Copernicus Sentinel data.
