CzechAgri study

Monitoring of agricultural crops using Sentinel imagery in the Czech Republic

Gisat has been contracted to implement CzechAgri study focusing on full country demonstration of integrated use of Sentinel 1&2 imagery for agricultural monitoring.

The CzechAgri study was jointly initiated in December 2015 by DG JRC, ESA and SZIF (The Czech State Agricultural Intervention Fund). It is set up as a proof-of-concept of what could be achieved in Europe by analyzing Sentinel imagery with the combined use of the national Land Parcel Identification System (LPIS) and a sub-sample of IACS declarations for calibration and validation. CzechAgri intends to be an R&D contribution to the preparation of future Copernicus service components in support of Agriculture as recently proposed to the Copernicus User Forum by DG GROW.

CzechAgri is run within the ESA Sentinel-2 for Agriculture project managed by the Université Catholique de Louvain. The aim of the study is to demonstrate the unprecedented capabilities of the Copernicus Sentinels by pilot agricultural crop mapping at national scale in 2015 and 2016. Combined time series of radar Sentinel 1 and optical Sentinel 2 imagery (complemented by Landsat 7&8 imagery) are processed and analyzed to provide full country crop map products covering the 2015 and 2016 crop vegetation season. The initial results at national scale have been presented at the 2016 European Space Agency Living Planet Symposium held in May in Prague. The results included the independent accuracy analysis and comparison of SAR and multispectral data performance.
