Enhanced classification of land cover through joint analysis of Sentinel 1 and Sentinel 2 data

Kurzfassung

The new European missions Sentinel 1 and Sentinel 2 bring added value to the Earth Observation market for land applications by providing timely high quality products with complementary information. The efficient and effective exploitation of the vast amounts of data already delivered by Sentinel 1, combined with the data delivered by Sentinel 2 is mandatory in order to get improved capabilities for the understanding and modelling of land cover classes dynamic and synergy. In this context, this paper discusses a potential methodology for Sentinel 1 and Sentinel 2 joint analysis and highlights the benefits brought by the increased information yielded by putting together these two kinds of data. To this end, the proposed approach follows the next steps: data pre-processing and registration, data representation and combined feature extraction, data classification and interpretation. The results are emphasized on urban and agricultural areas of high heterogeneity.
