Mapping biophysical variables from solar and thermal infrared remote sensing : focus on agricultural landscapes with spatial heterogeneity Jacob Frédéric auteur aut IRD Weiss M. auteur aut IRD text journalArticle eng text/pdf born digital access This letter closes a Special Stream that focuses on spatial heterogeneity when mapping biophysical variables over agricultural landscape from solar and thermal infrared remote sensing. We propose an overview of the highlights from prior research, we report the main results of the Special Stream, and we discuss future directions. The main outcomes of the Special Stream are related to: 1) the impact on the remotely sensed signal of canopy vertical distribution, shadowing effects, and multiple scattering; 2) the notion of spatial resolution limit in relation to spatial heterogeneity; and 3) the definition of an optimal sampling strategy to spatialize ground measurements. specialized Agricultural landscape downscaling forestry remote sensing spatial heterogeneity upscaling 126 076 072 IEEE Geoscience and Remote Sensing Letters 11 10 1844-1848 2014 1545-598X https://www.documentation.ird.fr/hor/fdi:010062270 10.1109/lgrs.2014.2313592 1545-598X [F B010062270] https://www.documentation.ird.fr/hor/fdi:010062270 https://www.documentation.ird.fr/intranet/publi/2014/07/010062270.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2014-07-24 2023-02-22 fdi:010062270 fre
