    • Detection and segmentation of vine canopy in ultra-high spatial resolution RGB imagery obtained from unmanned aerial vehicle (UAV) :a case study in a commercial vineyard 

      Poblete Echeverria, Carlos; Olmedo, Guillermo Federico; Ingram, Ben; Bardeen, Matthew (2017)
      The use of Unmanned Aerial Vehicles (UAVs) in viticulture permits the capture of aerial Red-Green-Blue (RGB) images with an ultra-high spatial resolution. Recent studies have demonstrated that RGB images can be used to ...
    • Estimación del avance urbano sobre la interfase urbano-rural del oasis norte de la provincia de Mendoza. Análisis temporal y espacial 

      Olmedo, Guillermo Federico; Navarro Canafoglia, Valentina; Perez, Martin Alberto (2016-01-01)
      El cambio de uso del suelo provocado por el avance urbano indiscriminado, se torna critico en agro ecosistemas de regadío ubicados en zonas áridas y semiáridas tal es el caso del Oasis Norte de Mendoza, donde la mancha ...
    • Machine learning in space and time for modelling soil organic carbon change 

      Heuvelink, Gerard B.M.; Angelini, Marcos Esteban; Poggio, Laura; Bai, Zhanguo; Batjes, Niels H.; van den Bosch, Rik; Bossio, Deborah; Estella, Sergio; Lehmann, Johannes; Olmedo, Guillermo Federico; Sanderman, Jonathan (Wiley, 2020-05-20)
      Spatially resolved estimates of change in soil organic carbon (SOC) stocks are necessary for supporting national and international policies aimed at achieving land degradation neutrality and climate change mitigation. In ...
    • No silver bullet for digital soil mapping: country-specific soil organic carbon estimates across Latin America 

      Guevara, Mario; Olmedo, Guillermo Federico; Stell, Emma; Yigini, Yusuf; Aguilar Duarte, Yameli; Arellano Hernández, Carlos; Arévalo, Gloria E.; Arroyo-Cruz, Carlos Eduardo; Bolivar, Adriana; Bunning, Sally; Bustamante Cañas, Nelson; Cruz-Gaistardo, Carlos Omar; Davila, Fabian; Dell Acqua, Martín; Encina, Arnulfo; Figueredo Tacona, Hernán; Fontes, Fernando; Hernández Herrera, José Antonio; Ibelles Navarro, Alejandro Roberto; Loayza, Verónica; Manueles, Alexandra; Mendoza Jara, Fernando; Olivera, Carolina; Osorio Hermosilla, Rodrigo; Pereira, Gonzalo; Prieto, Pablo; Ramos, Iván Alexis; Rey Brina, Juan Carlos; Rivera, Rafael; Rodríguez-Rodríguez, Javier; Roopnarine, Ronald; Rosales Ibarra, Albán; Rosales Riveiro, Kenset Amaury; Schulz, Guillermo Andres; Spence, Adrián; Vargas, Ronald R.; Vargas, Rodrigo; Vasques, Gustavo M. (2018-08)
      Country-specific soil organic carbon (SOC) estimates are the baseline for the Global SOC Map of the Global Soil Partnership (GSOCmap-GSP). This endeavor is key to explaining the uncertainty of global SOC estimates but ...
    • Soil mapping based on landscape classification in the semiarid Chaco, Argentina 

      Angueira, Maria Cristina; Cruzate, Gustavo Adolfo; Zamora, Eduardo Maximo; Olmedo, Guillermo Federico; Sayago, J.M.; Castillejo González, Isabel Luisa (2016)
      The semiarid Chaco is an ecosystem shared by Argentina, Paraguay, Bolivia, and Brazil where land use changes from forest to commercial agriculture and social conflicts have been intensive during the last decade. These ...
    • Spatial distribution of soil carbon storage in desert shrubland ecosystems of northwest Mexico 

      Ayala-Niño, Fernando; Maya-Delgado, Yolanda; García-Calderón, Norma E.; Olmedo, Guillermo Federico; Guevara, Mario; Troyo-Diéguez, Enrique (Elsevier, 2020-12)
      The scarce information about soil carbon (C) storage in water-stressed ecosystems limits our understanding on soil contribution to the C cycle in arid zones. This study, performed in arid NW México: (i) estimated soil ...
    • Spatial prediction of soil organic carbon stocks in Ghana using legacy data 

      Owusu, Stephen; Yigini, Yusuf; Olmedo, Guillermo Federico; Omuto, Christian Thine (Elsevier, 2019-11)
      Soil organic carbon (SOC) is a major driver of the multiple functions of soils in the delivery of ecosystem services. While the spatial prediction and mapping of SOC stocks are of key importance for land managers to ...
    • Water: tools and functions to estimate actual evapotranspiración using Land Surface Energy Balance Models in R 

      Olmedo, Guillermo Federico; Ortega Farias, Samuel; Fuente Saiz, Daniel de la; Fonseca Luengo, David; Fuentes Peñailillo, Fernando (2016-12)
      The crop water requirement is a key factor in the agricultural process. It is usually estimated throughout actual evapotranspiration (ETa). This parameter is the key to develop irrigation strategies, to improve water use ...
