Here, we examine relationships between this ‘full’ set and maize yield. 15 Parameters per pixel are estimated over the US corn belt using ARC, to fully describe the phenology, soil, and crop status over time for typical behaviour. ARC is tested for a new model over an area of irrigated and rain-fed winter crop in South Africa. We find that care must be taken for episodic events, and robust filtering methods should be developed for ARC, but average magnitude and timing is well-expressed. We find that a robust yield model (over time and space) can be created at the county-level for maize using only EO parameters with RMSE of 704-938 kg/ha using a non-linear model, but the results are only slightly poorer if a linear model is used. It compares well to a model that also includes weather data, showing that a model can be driven by optical EO data alone. date: 2024-11-04 date_type: published publisher: Copernicus GmbH official_url: https://doi.org/10.5194/isprs-annals-x-3-2024-199-2024 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2337507 doi: 10.5194/isprs-annals-x-3-2024-199-2024 lyricists_name: Lewis, Philip lyricists_id: PELEW26 actors_name: Lewis, Philip actors_id: PELEW26 actors_role: owner full_text_status: public publication: ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences volume: X-3 pagerange: 199-206 issn: 2194-9050 citation: Lewis, Philip E; Yin, Feng; Gómez-Dans, Jose Luis; Weiß, Thomas; Adam, Elhadi; (2024) Crop Yield Mapping with ARC using only Optical Remote Sensing.
