Assessment of factors affecting shrub volume estimations using airborne discrete-return LiDAR data in Mediterranean areas

Description: Shrub vegetation is a key element of Mediterranean forest areas and it is necessary to develop tools that allow a precise knowledge of this vegetation. This study aims to predict shrub volume and analyze the factors affecting the accuracy of these estimations in small stands using airborne discrete-...

Estimation of shrub biomass by airborne LiDAR data in small forest stands

Description: The presence of shrub vegetation is very significant in Mediterranean ecosystems. However, the difficulty involved in shrub management and the lack of information about behavior of this vegetation means that these areas are often left out of spatial planning projects. Airborne LiDAR (Light Detection...

Mechanized methods for harvesting residual biomass from Mediterranean fruit tree cultivations

Description: [EN] This study evaluates the technology and work systems used in order to harvest residual biomass from pruning in the specific conditions of Mediterranean fruit orchards (narrow distances between crop-rows). Harvesting has been divided into several types of operations pruning, biomass alignment be...

Residual biomass calculation from individual tree architecture using terrestrial laser scanner and ground-level measurements

Description: Large quantity of residual biomass with possible energy and industrial end can be obtained from management operations of urban forests. The profitability of exploiting this resource is conditioned by the amount of existing biomass within urban community ecosystems. Prior research pointed out that re...

Six decades of changes in the riparian corridor of a Mediterranean river: A synthetic analysis based on historical data sources

Description: Riparian corridors in semi-arid Mediterranean environments are ecosystems of high biodiversity and complexity. However, they are threatened because of high levels of human intervention. River damming and related flow manipulation is considered as one of the most prominent human impacts on riparian c...

Estimation of chlorophyll «A» on the Mediterranean coast using a QuickBird image

Description: Remote sensing has proved a useful tool for monitoring and assessing water quality. However, little research has been conducted using satellite images with high spatial resolution to analyze coastal areas with high variability near shore. The objective of this research was to develop a model for est...

Estimation of wood volume and height of olive tree plantations using airborne discrete-return LiDAR data

Description: The aim of this study is to analyze methodologies based on airborne LiDAR (light detection and ranging) technology of low pulse density points (0.5m(-2)) for height and volume quantification of olive trees in Viver (Spain). A total of 29 circular plots, each with a radius of 20m, were sampled and th...
