Phenological structuring of multi-temporal rapideye imagergy

The simplified phenological model PHASE is presented which enables a quick and and ‘on the fly’ Germany-wide prediction of phenological phases. The PHASE model bases on the assumption of linear relations between observed phenological events and phase-specific accumulated temperatures. The model was designed as simple as possible and is adapted to the specific data situation in Germany regarding publicly available information on weather, phenology and elevation. On the example of the agricultural land use classes Grassland and Winter Wheat and a German test site, the model results are used for the detection of relations between optimal acquisition dates and specific phenological phases for the distinction of agricultural land use classes (phenological structuring).
