PhenoSAR (3)

The goal of the PhenoSAR Demmin project is to evaluate potential information inherent to the Sentinel-1 time series to monitor farmland. Hereby, a particular focus is set on phenological development. The expected result is a monitoring framework to detect various stages of plant growth and their transition. This framework is based on interferometric and polarimetric Sentinel-1 time series and the underlying information about changes in plant geometry. Additionally, this project focuses on the improved transferability and scalability of its approach. Hence, its primary platform of development is an open data cube environment. With the test site DEMMIN as the study area, the project is connected to ongoing research in the AgriSens DEMMIN 4.0 project as well as the German TERENO and international JECAM Initiatives
