A broad-scale analysis of the main factors determining the current structure and understory composition of Catalonian sub-alpine (Pinus uncinata Ram.) forests
(Oxford University Press, 2011-12-13)A broad-scale analysis of the structure and understory composition of Pyrenean mountain pine (Pinus uncinata Ram.) stands was performed using data from the Spanish National Forest Inventory. Twelve structure-based forest ... -
A decision support tool for assessing the impact of climate change on multiple ecosystem services
(MDPI, 2019-05-21)In the climate change era, forest managers are challenged to use innovative tools to encourage a sustained provision of goods and services. Many decision support tools (DSTs), developed to address global changes in forest ... -
A fire modeling approach to assess wildfire exposure of valued resources in central Navarra, Spain
(Springer Verlag, 2015-10-27)Wildfires are a growing threat to socio-economic and natural resources in the wildland-rural-urban intermix in central Navarra (Spain), where recent fast-spreading and spotting short fire events have overwhelmed suppression ... -
A general method for the classification of forest stands using species composition and vertical and horizontal structure
(Springer Nature, 2019)Key message. We present a novel approach to define pure- and mixed-forest typologies from the comparison of pairs of forest plots in terms of species identity, diameter, and height of their trees. Context. Forest typologies ... -
A LiDAR-Based System to Assess Poplar Biomass
(Springer-Verlag, 2016-06-21)This study evaluated the capabilities of a LiDAR-based system to characterize poplar trees for biomass production. The precision of the system was assessed by analyzing the relationship between the distance records and ... -
A method to obtain orange crop geometry information using a mobile terrestrial laser scanner and 3D modeling
(MDPI, 2017)LiDAR (Light Detection and Ranging) technology has been used to obtain geometrical attributes of tree crops in small field plots, sometimes using manual steps in data processing. The objective of this study was to develop ... -
A novel tool to assess the effect of intraspecific spatial niche variation on species distribution shifts under climate change
(Wiley, 2019)Aim Niche‐based models often ignore spatial variation in the climatic niche of a species across its occupied range and the related variation in the response to changing climate conditions. This assumption may lead to ... -
A review of methods and applications of the geometric characterization of tree crops in agricultural activities
(Elsevier, 2012)This paper presents the foundations and applications in agriculture of the main systems used for the geometrical characterization of tree plantations, including systems based on ultrasound, digital photographic techniques, ... -
A tractor-mounted scanning LIDAR for the non-destructive measurement of vegetative volume and surface area of tree-row plantations: a comparison with conventional destructive measurements
(Elsevier, 2009)The use of a low-cost tractor-mounted scanning Light Detection and Ranging (LIDAR) system for capable of making non-destructive recordings of tree-row structure in orchards and vineyards is described. Field tests consisted ... -
Advanced Technologies for the Improvement of Spray Application Techniques in Spanish Viticulture: An Overview
(MDPI, 2014)Spraying techniques have been undergoing continuous evolution in recent decades. This paper presents part of the research work carried out in Spain in the field of sensors for characterizing vineyard canopies and monitoring ... -
Agricultura de Precisión

Agricultura de Precisión: ¿Qué se oculta detrás del nombre?
(New Ag International SARL, 2017-01-01)El término Agricultura de Precisión (AP) se ha discutido mucho durante los últimos años en exhibiciones y conferencias sobre agricultura, encuentros profesionales, revistas y cafés. Por otra parte también se usan expresiones ... -
Agricultura y distribución de los recursos hidráulicos
(Eumedia, 1995)La historia de las civilizaciones se escribe también como la de la lucha permanente por disponer del agua necesaria para satisfacer las necesidades presentes y futuras, siendo ello motivo de contficto frecuente entre ... -
Airborne spray drift measurement using passive collectors and lidar systems
(Society of Photo-optical Instrumentation Engineers (SPIE), 2011)Minimization of the risk associated with spray applications requires a proper understanding of the spray drift phenomenon. This fact has led to the development of several techniques to measure the deposition on horizontal ... -
Algebraic path tracking to aid the manual harvesting of olives using an automated service unit
(Elsevier, 2016)Service units used in precision agriculture are able to improve processes such as harvesting, sowing, agrochemical application, and manure spreading. This two-part work presents, a path tracking controller based on an ... -
An automated disc infiltrometer for infiltration rate measurements using a microflowmeter
(Wiley, 2012)This work presents a new design of disc infiltrometer, which, associated with a microflowmeter (MF) and a solenoid valve set, makes it possible to automate the infiltration rate (Q) measurements at different soil pressure ... -
An Electronic Control System for Pesticide Application Proportional to the Canopy Width of Tree Crops
(Elsevier, 2006)A prototype of an electronic control system based on ultrasonic sensors and proportional solenoid valves for a proportional application to the canopy width of tree crops was mounted on an air-assisted sprayer. The sprayer ... -
Analysis of factors influencing deployment of fire suppression resources in Spain using artificial neural networks
(Italian Society of Silviculture and Forest Ecology (SISEF), 2015)In Spain, the established fire control policy states that all fires must be controlled and put out as soon as possible. Though budgets have not restricted operations until recently, we still experience large fires and ... -
Analysis of vineyard differential management zones and relation to vine development, grape maturity and quality
