Effective roughness modelling as a tool for soil moisture retrieval from C-and L-band SAR
(Copernicus Publications, 2011)
Artículo / Artikulua,
Soil moisture retrieval from Synthetic Aperture Radar (SAR) using state-of-the-art backscatter models is not fully operational at present, mainly due to difficulties involved in the parameterisation of soil surface ...
On the added value of quad-pol data in a multi-temporal crop classification framework based on RADARSAT-2 imagery
(MDPI, 2016)
Artículo / Artikulua,
Polarimetric SAR images are a rich data source for crop mapping. However, quad-pol
sensors have some limitations due to their complexity, increased data rate, and reduced coverage
and revisit time. The main objective of ...
Clasificación de cultivos en la zona media de Navarra mediante imágenes radar polarimétricas
(Universidad Politécnica de Valencia, 2010)
Artículo / Artikulua,
Navarra lleva años empleando la técnica de clasificación
supervisada de imágenes multiespectrales
de satélite para la realización de la estadística
agraria. La cubierta nubosa, muy
habitual en esta zona, limita e incluso ...
Evaluation of TOPLATS on three Mediterranean catchments
(Elsevier, 2016)
Artículo / Artikulua,
Physically based hydrological models are complex tools that provide a complete description of the different processes occurring on a catchment. The TOPMODEL-based Land-Atmosphere Transfer Scheme (TOPLATS) simulates water ...
Evaluation of surface roughness parameters in agricultural soils with different tillage conditions using a laser profile meter
(Elsevier, 2016)
Artículo / Artikulua,
Surface roughness crucially affects the hydrological and erosive behaviours of soils. In agricultural areas surface roughness is directly related to tillage, whose action strongly affects the key physical properties of ...
Automatic detection of uprooted orchards based on orthophoto texture analysis
(MDPI, 2017)
Artículo / Artikulua,
Permanent crops, such as olive groves, vineyards and fruit trees, are important in European agriculture because of their spatial and economic relevance. Agricultural geographical databases (AGDBs) are commonly used by ...
The added value of stratified topographic correction of multispectral images
(MDPI, 2016)
Artículo / Artikulua,
Satellite images in mountainous areas are strongly affected by topography. Different studies demonstrated that the results of semi-empirical topographic correction algorithms improved when a stratification of land covers ...
Effects of spatial sampling interval on roughness parameters and microwave backscatter over agricultural soil surfaces
(MDPI, 2016)
Artículo / Artikulua,
The spatial sampling interval, as related to the ability to digitize a soil profile with a certain number of features per unit length, depends on the profiling technique itself. From a variety of profiling techniques, ...
Validation of a simplified model to generate multispectral synthetic images
(MDPI, 2015)
Artículo / Artikulua,
A new procedure to assess the quality of topographic correction (TOC) algorithms applied to remote sensing imagery was previously proposed by the authors. This procedure was based on a model that simulated synthetic scenes, ...
Multi-criteria evaluation of topographic correction methods
(Elsevier, 2016)
Artículo / Artikulua,
In the last decades, several topographic correction methods (TOC) have been proposed, but there is not an agreement on the best method. Furthermore, different evaluation criteria have been used in the past, and there is ...
