24 p, 12.6 MB Modelling Two Sugarcane Agro-Industrial Yields Using Sentinel/Landsat Time-Series Data and Their Spatial Validation at Different Scales in Costa Rica / Alemán-Montes, Bryan (Universitat Autònoma de Barcelona. Departament de Geografia) ; Zabala Torres, Alaitz (Universitat Autònoma de Barcelona. Departament de Geografia) ; Henríquez, Carlos (Universidad de Costa Rica. Centro de Investigaciones Agronómicas) ; Serra Ruiz, Pere (Universitat Autònoma de Barcelona. Departament de Geografia)
Sugarcane production is a relevant socioeconomic activity in Costa Rica that requires tools to improve decision-making, particularly with the advancement of agronomic management using remote sensing (RS) techniques. [...]

9 p, 4.0 MB Evaluation and normalization of topographic effects on vegetation indices / Chen, Rui (Southwest Jiaotong University) ; Yin, Gaofei (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Liu, Guoxiang (Southwest Jiaotong University) ; Li, Jing (Chinese Academy of Sciences. Institute of Remote Sensing and Digital Earth) ; Verger, Aleixandre (Centre de Recerca Ecològica i d'Aplicacions Forestals)
The normalization of topographic effects on vegetation indices (VIs) is a prerequisite for their proper use in mountainous areas. We assessed the topographic effects on the normalized difference vegetation index (NDVI), the enhanced vegetation index (EVI), the soil adjusted vegetation index (SAVI), and the near-infrared reflectance of terrestrial vegetation (NIRv) calculated from Sentinel-2. [...]

15 p, 4.6 MB Early diagnosis of vegetation health from high-resolution hyperspectral and thermal imagery : lessons learned from empirical relationships and radiative transfer modelling / Hernández-Clemente, Rocío (Swansea University. Department of Geography (UK)) ; Hornero, Alberto (Swansea University. Department of Geography (UK)) ; Mottus, Matti (Technical Research Centre of Finland) ; Peñuelas, Josep (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; González-Dugo, Victoria (Consejo Superior de Investigaciones Científicas (Espanya). Instituto de Agricultura Sostenible) ; Jiménez, Juan Carlos (Universitat de València) ; Suárez, Lola (University of Melbourne. School of Agriculture and Food & Department of Infrastructure Engineering (Australia)) ; Alonso, Luis (Universitat de València) ; Zarco-Tejada, Pablo J. (University of Melbourne. School of Agriculture and Food & Department of Infrastructure Engineering (Australia))
Purpose of Review: We provide a comprehensive review of the empirical and modelling approaches used to quantify the radiation-vegetation interactions related to vegetation temperature, leaf optical properties linked to pigment absorption and chlorophyll fluorescence emission, and of their capability to monitor vegetation health.

53 p, 1.4 MB Matching the phenology of net ecosystem exchange and vegetation indices estimated with MODIS and FLUXNET in-situ observations / Balzarolo, Manuela (Universiteit Antwerpen. Departement Biologie) ; Vicca, Sara (Universiteit Antwerpen. Departement Biologie) ; Nguy-Robertsonb, A. L. (University of Nebraska-Lincoln. School of Natural Resource Sciences) ; Bonal, Damien (Institut National de la Recherche Agronomique (França)) ; Elbers, J. A. (Alterra (Organization : Netherlands)) ; Fu, Y. H. (Universiteit Antwerpen. Departement Biologie) ; Grünwald, Thomas (Technische Universität Dresden. Institut für Hydrologie und Meteorologie) ; Horemans, Joanna A. (Universiteit Antwerpen. Departement Biologie) ; Papale, D. (Università degli studi della Tuscia. Dipartimento per l'Innovazione dei sistemi biologici, agroalimentari e forestali) ; Peñuelas, Josep (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Suyker, A. (University of Nebraska-Lincoln. School of Natural Resource Sciences) ; Veroustraetej, F. (Universiteit Antwerpen. Department of Bioscience Technik)
Shifts in ecosystem phenology play an important role in the definition of inter-annual variability of net ecosystem carbon uptake. A good estimate at the global scale of ecosystem phenology, mainly that of photosynthesis or gross primary productivity (GPP), may be provided by vegetation indices derived from MODIS satellite image data.

11 p, 1.3 MB Herramienta de soporte para el análisis de nitrogenado de cultivos / Fernández Álvarez, Jerónimo ; Ponsa Mussarra, Daniel, dir. (Universitat Autònoma de Barcelona. Departament de Ciències de la Computació) ; Universitat Autònoma de Barcelona. Escola d'Enginyeria
La agricultura actualmente está tecnificándose con el objetivo de aumentar el rendimiento. Hoy en día, los sistemas de detección remota se utilizan para conocer distintos indicadores del cultivo (vigor, estrés hídrico, estimación de cosecha) y se obtienen imágenes aéreas multiespectrales que, debidamente procesadas, caracterizan los cultivos. [...]
Nowadays, the agriculture is tecnifying with the aim of raising its performance. At the moment, the remote sensing systems are being used so as to survey different crop indicators (vigour, hidric stress, harvest prediction), and multispectral aerial images are obtained, if they are properly processed, to characterize the crops. [...]
