Workshop report at the Earth Observation Research Hub – October 26, 2022

October 20, 2022

We are glad to announce our next workshop report at the Earth Observation Research Hub. On the 26th of October, Maninder Singh Dhillon et al. will talk about “Multisource Data Fusion for Spatiotemporal Yield Modelling Winter Wheat and Oil Seed Rape“.

Abstract

The increasing availability and variety of global satellite products and the rapid development of new algorithms provide great potential to generate a new level of data with different spatial, temporal, and spectral resolutions. However, the ability of these synthetic spatiotemporal datasets for accurately mapping and monitoring e.g., crop yields on different spatial scales remains underexplored. This study aims to identify the most suited synthetic satellite inputs for estimating crop yields by discovering the best spatial and temporal resolutions on a regional scale. The study explores and discusses the suitability of six different synthetic NDVI products (e.g., MOD13Q1, Landsat-MOD13Q1, and Sentinel-2-MOD13Q1) incorporated separately into two widely used crop growths models (i.e., WOFOST and LUE) for winter wheat and oil seed rape yield forecasts in Bavaria in 2019. For both crops, the synthetic products’ high spatial and temporal resolution promise to result in higher yield modeling accuracies with LUE and WOFOST. The study recommends the further use of its findings for implementing and validating the long-term crop yield time series in different regions of the world.
