Carotenoid content estimation in a heterogeneous conifer forest using narrow-band indices and PROSPECT + DART simulations
(Science Direct, 2012)
The present study explored the use of narrow-band indices formulated in the visible spectral region at leaf and canopy levels to estimate carotenoid content. The research area was a pine forest affected by decline processes. ...
Estimating leaf carotenoid content in vineyards using high resolution hyperspectral imagery acquired from an unmanned aerial vehicle (UAV)
(Science Direct, 2013)
Chlorophyll a+b (Ca+b) and carotenoids (Cx+c) are leaf pigments associated with photosynthesis, participation in light harvesting and energy transfer, quenching and photoprotection. This manuscript makes progress on ...
Assessing structural effects on PRI for stress detection in conifer forests
(Science Direct, 2011)
The retrieval of indicators of vegetation stress from remote sensing imagery is an important issue for the accurate assessment of forest decline. The Photochemical Reflectance Index (PRI) has been demonstrated as a ...
Global monitoring of soil multifunctionality in drylands using satellite imagery and field data
(Zoological Society of London, 2023)
Models derived from satellite image data are needed to monitor the status of terrestrial ecosystems across large spatial scales. However, a remote sensing-based approach to quantify soil multifunctionality at the global ...
Evaluating models to assess the distribution of Buxus balearica in southern Spain
(Wiley, 2010)
uestion: Which is the best model to predict the habitat distribution of Buxus balearica Lam. in southern Spain?
Location: Málaga and Granada, Spain, across an area of 38 180 km2.
Methods: Prediction models based on ...
Monitoring post-fire regeneration in Mediterranean ecosystems by employing multitemporal satellite imagery
(CSIRO PUBLISHING, 2009)
Fire-damaged ecosystems have often been monitored by applying a combination of field survey information and vegetation indices derived from remotely sensed data. Furthermore, it has been demonstrated that remotely sensed ...
An automatic trunk-detection system for intensive olive harvesting with trunk shaker.
(Elsevier, 2018)
Trunk shakers are widely used for olive harvesting, being the main detachment system for
fruit harvesting. In recent decades, the components of trunk shakers have evolved at
mechanical, hydraulic and control levels. ...
Assessing the effects of forest health on sun-induced chlorophyll fluorescence using the FluorFLIGHT 3-D radiative transfer model to account for forest structure
(Science Direct, 2017)
Sun-induced fluorescence (SIF) has been proven to serve as a proxy of photosynthesis activity and therefore, as an early indicator of physiological alterations for global monitoring of vegetation. However, the interpretation ...
Hyperspectral and multispectral satellite sensors for mapping chlorophyll content in a Mediterranean Pinus sylvestris L. plantation
(Science Direct, 2014)
A new generation of narrow-band hyperspectral remote sensing data offers an alternative to broad-band multispectral data for the estimation of vegetation chlorophyll content. This paper examines the potential of some of ...
Semi-automated stand delineation in Mediterranean Pinus sylvestris plantations through segmentation of LiDAR data: the influence of pulse density
(Science Direct, 2017)
Traditionally, forest-stand delineation has been assessed based on orthophotography. The application of LiDAR has improved forest management by providing high-spatial-resolution data on the vertical structure of the forest. ...
