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 ...
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 ...
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 ...
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 ...
Evaluation of 2D models for the prediction of surface depression storage using realistic reference values
(Wiley, 2016)
Artículo / Artikulua,
Depression storage (DS) is the maximum storage of precipitation and runoff in the soil surface at a given slope. The DS is determined by soil roughness that in agricultural soils is largely affected by tillage. The direct ...
Evaluación multitemporal de métodos de corrección topográfica mediante el uso de imágenes sintéticas multiespectrales
(Asociación Española de Teledetección, 2014)
Artículo / Artikulua,
En este trabajo se presentan los resultados de la evaluación multitemporal de varios métodos de corrección topográfica (TOC), cuya bondad se determina de forma cuantitativa mediante el uso de imágenes sintéticas multiespectrales ...
Desarrollo de productos avanzados para la misión SEOSAT/Ingenio
(Universitat Politecnica de Valencia, 2016)
info:eu-repo/semantics/article,
SEOSAT/Ingenio es la futura misión española de observación de la Tierra en el óptico en alta resolución espacial. Mientras que los productos de imagen a Nivel 1, radiancias geo-referenciadas a nivel de sensor, se encuentran ...
