El inventario forestal por métodos de masa con tecnología LiDAR está implantado operativamente en España. Una de sus principales limitaciones es el coste de adquisición de datos, que supone largos periodos entre campañas de captura, lo que, unido a la obsolescencia del mismo ante perturbaciones naturales o artificiales, especialmente en ecosistemas...
La caracterización de la cantidad y distribución espacial de la biomasa aérea en masas arboladas es clave para evaluar el riesgo de incendio y su severidad potencial, así como para planificar actuaciones preventivas orientadas a reducir su impacto. La tecnología LiDAR permite generar cartografía de variables descriptivas de la estructura de los com...
Three-dimensional (3D) data from airborne laser scanning (ALS) and, more recently, digital aerial photogrammetry (DAP) have been successfully used to model forest attributes. While multi-temporal, wall-to-wall ALS data is not usually available, aerial imagery is regularly acquired in many regions. Thus, the combination of ALS and DAP data provide a...
Objetivos ✓ Elaborar un inventario forestal regional de las ocho especies más representativas, que suponen más del 80% de los bosques riojanos. ✓ Desarrollar una metodología orientada a mejorar el Mapa Forestal Español mediante la integración de información multiespectral de Sentinel-2 y datos LiDAR. 1. Procesado LiDAR 2016 en celdas de 25x25 m: MD...
Introduction:
Airborne laser scanning (ALS) has been widely used for accurate characterization of vegetation structure, and it is frequently used as an operational technology in forest mapping. A complete ALS coverage of Spain is freely offered by the Spanish National Plan of Aerial Orthophotography with an expected updating time of six years. In...
Due to the increasing importance of mangroves in climate change mitigation projects, more accurate and cost-effective aboveground biomass (AGB) monitoring methods are required. However, field measurements of AGB may be a challenge because of their remote location and the difficulty to walk in these areas. This study is based on the Livelihoods Fund...

Vertical fuel structure is critical for fire hazard assessment in forest ecosystems. Forest stands with ladder fuels are more prone to crown fires because of canopy fuel continuity. However, characterization of ladder fuels is difficult in the field and few studies have developed explicit measurement procedures to account for these hazardous fuel s...
Airborne laser scanning (ALS) is commonly used in forest mapping. Full coverage of ALS is already available in some countries to provide high-detailed terrain elevation models. These kinds of data sets have been shown to offer great potential in forest mapping. However, it presents some drawbacks such as the resampling periods may be longer than re...
Resumen: La gestión forestal es una de las actividades de compensación de emisiones contempladas en el protocolo de Kioto, pero aún no está aplicándose en España por falta de metodologías y experiencias. El proyecto LIFE ForestCO2 pretende dar un importante impulso a los sumideros de carbono generados a través de actuaciones de Gestión Forestal Sos...
Gran parte de los montes españoles se encuentran en una situación de ausencia de gestión debido a
la baja rentabilidad de los productos tradicionales y a los limitados presupuestos de que disponen los
gestores para su mejora. La captación de inversión privada mediante la compensación de emisiones
de carbono en las estrategias de responsabilidad soc...
La tecnología LiDAR está modificando sustancialmente la forma de generar información útil para la
toma de decisiones en la planificación y la gestión forestal.
En el caso concreto de montes productores de corcho los métodos tradicionales de inventario se
basan en la medición de variables dendrométricas en muestreos sistemáticos de campo, para aplic...
In Spain, the National Geographic Institute (IGN) has full nationwide LiDAR coverage within the Spanish National Plan of Aerial Orthophotography (PNOA-LiDAR). LiDAR information captured within this program has a mean density of 0.5 points/m2 and vertical RMSE ≤ 0.20 m. Hence, the use of low density LiDAR data captured is the main option to signific...
Tropical forests play a key role in global carbon cycle. Reducing Emissions from Deforestation and forest Degradation (REDD +) program requires reliable mechanisms for Monitoring, Reporting and Verification (MRV). In this regard, new methods must be developed using updated technologies to assess carbon stocks. The combination of LiDAR technology an...
