Closing Grassland Yield Data Gaps

The research contract with 'Die Bundesanstalt Statistik Österreich' focuses on developing algorithms and data access structures to apply existing models for calculating annual yields and feed quality (crude protein content) in various grassland cutting systems. The know-how was developed within the FFG ASAP SatGrass project at the Institute of Geomatics. The research services include the extension of the following aspects: - Database Evaluation: Assessing a database for SatGrass model parameters using satellite data at the parcel level (IACS-GIS). - Start of Growing Season (SOS) Estimation: Developing algorithms to determine SOS for mown meadows using alternative satellite data, replacing the limited-time availability of MODIS data, and generating SOS time series. - Cut Detection Enhancement: Advancing cut detection methods based on Sentinel-1 and Sentinel-2 time series.
