Site-related measures in the agricultural funding and the intervention scheme are currently checked with time - and cost-intensive on spot checks. A Web application, based on remote sensing data, should change that.
The good spatial coverage and high temporal resolution of the Sentinel satellites of the Earth observation programme of Copernicus today allow a close temporal recording of agricultural land use and identification of use changes.
With the help of satellite data, administrative authorities can reduce time - and cost-intensive on spot checks in the area of site monitoring and automate workflows as extensively as possible. Within the framework of the project "timeStamp", scientists of the Thünen Institute are developing a web application to evaluate whether the declared land use corresponds with the actual land use.
The web application is developed for two applications: a) to monitor catch crop sites and b) for the check compensation sites. Compensation sites are areas that are ecologically enhanced to compensate for interventions in nature and landscape.

The following steps will be undertaken:
Thus, an automated decision support system for site controls is developed that can be integrated in the monitoring routines of the authorities.
The analysis of Copernicus satellite data --Sentinel-1 (radar data) and Sentinel-2 (spectral data) -- on use changes on the sites can be described by appropriate metrics (measures) and derived indices. In the processing module, the satellite image time series are automatically analysed in regard of the land use, considering the test indicators. The web application serves the upload or download of data (including geometry of the sites to be tested) and the transfer of the evaluation results.
What are appropriate metrics, indicators, and algorithms (e.g., NDVI, matching with phenological pattern profiles, MSAVI for unsealing) to recognize the lifetime of catch crops and detect interventions on nature and landscape under the Federal Nature Conservation Act?
