On the influence of acquisition geometry in backscatter time series over wheat
(Elsevier, 2022)
Artículo / Artikulua,
Dense time series of Sentinel-1 imagery are an invaluable information source for agricultural applications. Multiple orbits can observe a specific area and their combination could improve the temporal resolution of the ...
A diachronic analysis of a changing landscape on the Duero river borderlands of Spain and Portugal combining remote sensing and ethnographic approaches
(MDPI, 2021)
Artículo / Artikulua,
The Arribes del Duero region spans the border of both Spain and Portugal along the Duero
River. On both sides of the border, the region boasts unique human‐influenced ecosystems. The
borderland landscape is dotted with ...
Assessment of atmospheric correction methods for Sentinel-2 images in Mediterranean landscapes
(Elsevier, 2018)
info:eu-repo/semantics/article,
Atmospheric correction of optical satellite imagery is an essential pre-processing for modelling biophysical variables, multi-temporal analysis, and digital classification processes. Sentinel-2 products available for users ...
Evaluation of terrestrial laser scanner and structure from motion photogrammetry techniques for quantifying soil surface roughness parameters over agricultural soils
(Wiley, 2020)
info:eu-repo/semantics/article,
The surface roughness of agricultural soils is mainly related to the type of tillage performed, typically consisting of oriented and random components. Traditionally, soil surface roughness (SSR) characterization has been ...
On the influence of spatial resolution in soil surface roughness characterization using Tls and Sfm techniques
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
Soil surface roughness strongly affects the scattering of microwaves and determines the backscattering coefficient observed by SAR (Synthetic Aperture Radar) sensors. The aim of this study is to analyze the influence of ...
Inter-comparison of atmospheric correction methods on Sentinel-2 images applied to croplands
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
Atmospheric correction of high resolution satellite scenery is a necessary preprocessing step for applications where bottom of atmosphere (BOA) reflectances are needed. The selection of the best atmospheric correction ...
Crop type mapping based on Sentinel-1 backscatter time series
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
The high revisit time of Sentinel-1 (S1) observations enables the design of crop type mapping approaches exploiting the backscatter time series observed for the different crops. The objective of this study is to propose a ...
Evaluation of soil moisture estimation techniques based on Sentinel-1 observations over wheat fields
(Elsevier, 2023)
Artículo / Artikulua,
Soil moisture (SM) is a key variable in agriculture and its monitoring is essential. SM determines the amount of
water available to plants, having a direct impact on the development of crops, on the forecasting of crop ...
Clasificación de usos y cubiertas del suelo y análisis de cambios en los alrededores de la Reserva Ecológica Manglares Churute (Ecuador) mediante una serie de imágenes Sentinel-1
(Universidad Politécnica de Valencia, 2020)
info:eu-repo/semantics/article,
La gestión de las áreas naturales protegidas frecuentemente obvia la importancia que tiene el territorio que rodea el perímetro del espacio protegido (zona de amortiguación). Estas zonas pueden ser el origen de impactos ...
New methodology for wheat attenuation correction at C-Band VV-polarized backscatter time series
(IEEE, 2022)
Artículo / Artikulua,
Wheat is one of the most important crops worldwide, and thus the use of remote sensing data for wheat monitoring has attracted much interest. Synthetic Aperture Radar (SAR) observations show that, at C-band and VV polarization, ...
