Influence of surface roughness measurement scale on radar backscattering in different agricultural soils
(IEEE, 2017)
Artículo / Artikulua,
Soil surface roughness strongly affects the scattering of microwaves on the soil surface and determines the backscattering coefficient (σ 0 ) observed by radar sensors. Previous studies have shown important scale issues ...
Influence of surface roughness sample size for C-band SAR backscatter applications on agricultural soils
(IEEE, 2017)
Artículo / Artikulua,
Soil surface roughness determines the backscatter coefficient observed by radar sensors. The objective of this letter was to determine the surface roughness sample size required in synthetic aperture radar applications and ...
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, ...
On the assimilation set-up of ASCAT soil moisture data for improving streamflow catchment simulation
(Elsevier, 2018)
Artículo / Artikulua,
Assimilation of remotely sensed surface soil moisture (SSM) data into hydrological catchment models has been identified as a means to improve stream flow simulations, but reported results vary markedly depending on the ...
Factors controlling sediment export in a small agricultural watershed in Navarre (Spain)
(Elsevier, 2012)
Artículo / Artikulua,
It is recognised that the hydrological and erosion processes in watersheds are very much conditioned by
the (inter)action of a number of variables. This paper covers a 15-year period of studying those factors
that have ...
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 ...
Synthetic images for evaluating topographic correction algorithm
(IEEE, 2013)
Artículo / Artikulua,
In the last years, many topographic correction (TOC) methods have been proposed to correct the illumination differences between the areas observed by optical remote sensors. Although the available number of TOC methods is ...
Multitemporal evaluation of topographic correction algorithms using synthetic images
(SPIE, 2012)
Contribución a congreso / Biltzarrerako ekarpena,
Land cover classification and quantitative analysis of multispectral data in mountainous regions is considerably hampered by the influence of topography on the spectral response pattern. In the last years, different ...
