Última Temporal monitoring of corn (Zea mays L.) yield using grami model, satellite imagery, and climate data in a semi-arid area CIGR Journal Asghari, Fatemeh; Sharif, Mohammad; Kheirkhah Zarkesh, Mirmasoud; Porhemmat, Jahangir. Corn yield estimation constitutes a critical issue in agricultural management and food supply, especially in demographic pressure and climate change contexts. In light of precision and smart agriculture, this study aims to develop a diagnostic approach to temporally monitor and estimate corn yields using GRAMI (a model for simulating the growth and yield of grain crops), satellite images, and climate data at regional scale. The GRAMI-corn model is controlled by vegetation indices (VIs) derived from Landsat 8 satellite images and calibrated by climate data. The model performed and validated using information collected from twenty-five cornfields in a semiarid region in Ravansar, Iran. The average of under- or over-estimate yields was 919 kg ha−1. In...

Ano: 2022 URL: http://www.cigrjournal.org/index.php/Ejounral/article/view/7241 The Advantages of Landsat 8-OLI-Derived Suspended Particulate Matter Maps for Monitoring the Subtidal Extension of Amazonian Coastal Mud Banks (French Guiana) ArchiMer Zorrilla, Noelia Abascal; Vantrepotte, Vincent; Gensac, Erwan; Huybrechts, Nicolas; Gardel, Antoine. The coast of French Guiana is characterised by the northwestward migration of large mud banks alongshore and by high concentrations of suspended particulate matter (SPM) resulting from the strong influence of the Amazon River outflow. Surface OLI SPM concentration, linked to the footprint of the subtidal part of mud banks due to resuspension and migration processes, was used to develop a method to estimate the location of this footprint. A comparison of the results from this method with those obtained by locating the limit of the wave damping, which characterises muddy coasts, revealed good performance of the method based on recurring SPM values. The migration rates of the mud banks in French Guiana were calculated according to the delimitation of their...
