Analysis of ASAR/Envisat polarimetric backscattering characteristics of Doñana National Park wetlands
Martí Cardona, Belén; López Martínez, Carlos; Dolz Ripollès, Josep (IEEE Press. Institute of Electrical and Electronics Engineers, 2009)
Text en actes de congrés
Accés obertDoñana National Park wetlands, in southwest Spain, undergo yearly cycles of inundation and drying out. These cycles, together with great extensions of annual helophytes, make of Doñana a rapidly changing environment. 43 ... -
Envisat/ASAR images for the calibration of wind drag action in the Doñana wetlands 2D hydrodynamic model
Ramos Fuertes, Anaïs; Martí Cardona, Belén; Bladé i Castellet, Ernest; Dolz Ripollès, Josep (2014)
Article
Accés obertDoñana National Park wetlands are located in southwest Spain, on the right bank of the Guadalquivir River, near the Atlantic Ocean coast. The wetlands dry out completely every summer and progressively flood again throughout ... -
La teledetección como fuente de información para los modelos bidimensionales: aplicación al modelo Íber de las marismas de Doñana
Martí Cardona, Belén; Ramos, Anaïs; Bladé i Castellet, Ernest; Duc Tran, Thunh; Dolz Ripollès, Josep (2011)
Text en actes de congrés
Accés restringit per política de l'editorialLa modelación hidrodinámica en dos dimensiones plantea exigencias de hardware relativas a la capacidad computacional, pero también en lo referente a la dimensión espacial de los datos con los que se alimenten los modelos. ... -
Local isotropy indicator for SAR image filtering: application to Envisat/ASAR images of the Doñana Wetland
Martí Cardona, Belén; López Martínez, Carlos; Dolz Ripollès, Josep (2015-04)
Article
Accés obertThis paper explores a geometrical and computationally simple operator, named Ds, for local isotropy assessment on SAR images. It is assumed that isotropic intensity distributions in natural areas, either textured or ... -
Local texture stationarity indicator for filtering Doñana wetlands SAR images
Martí Cardona, Belén; López Martínez, Carlos; Dolz Ripollès, Josep (IEEE, 2012)
Text en actes de congrés
Accés obertThis paper defines a new operator, named Ds, for local texture stationarity assessment on SAR images. . The aim is to discriminate heterogeneous targets from land cover types of high normalized variance values, as those ... -
Modelación numérica (2D y 3D) de la hidrodinámica en el entorno de la confluencia Ebro-Segre

NRCS-CN estimation from onsite and remote sensing data for management of a reservoir in the eastern Pyrenees
Sanz Ramos, Marcos; Martí Cardona, Belén; Bladé i Castellet, Ernest; Seco, Raquel Irene; Amengual Pou, Arnau; Roux, Helene; Romero March, Romualdo (2020-09)
Article
Accés obertOnsite and Earth observation (EO) data are used for the calibration of the Natural Resources Conservation Service curve number (NRCS-CN) value in a hydrological simulation model. The model was developed for La Muga catchment ... -
On the synergistic use of Envisat/ASAR imagery and ancillary spatial data for monitoring Doñana wetlands
Martí Cardona, Belén; Dolz Ripollès, Josep (2013)
Comunicació de congrés
Accés obertA time series of Envisat/ASAR images was acquired for monitoring the inundation evolution in Doñana National Park wetlands. Flood mapping from the ASAR data alone was unfeasible due to the complex casuistic of Doñana’s ... -
Spaceborne SAR imagery for monitoring the inundation in the Doñana wetlands
Martí Cardona, Belén (Universitat Politècnica de Catalunya, 2014-05-14)
Tesi
Accés obertThe Doñana wetlands, in Southwest Spain, undergo yearly cycles of inundation in fall and drying out during the spring season. As any wetland ecosystem, Doñana depends critically on its water resources. Important monitoring ... -
Wetland inundation monitoring by the synergistic use of ENVISAT/ASAR imagery and ancilliary spatial data
Martí Cardona, Belén; Dolz Ripollès, Josep; López Martínez, Carlos (2013)
Article
Accés restringit per política de l'editorialon the water resources. In a scenario of climate change and increased anthropogenic pressure, detailedmonitoring of the water resources provides a fundamental tool to assess the ecosystem health and identify potential ...
