[EN] This paper presents a new methodological process for detecting the instantaneous land-water border at sub-pixel level from mid-resolution satellite images (30 m/pixel) that are freely available worldwide. The new ...
In this article, a technique towards the generation of hybrid raster-attributes map for use in mobile devices is described. Our solution is based on coding the map attributes within an image using RGB values. The designed ...
[EN] Satellite images may constitute a useful source of information for coastal monitoring as long as it is possible to manage them in an efficient way and to derive precise indicators of the state of the beaches. In the ...

[EN] Beaches are spaces of paramount importance for coastal societies currently threatened by coastal erosion. Their preservation requires accurate quantification of their changes in order to understand their behavior and ...
[EN] A statistical analysis of the results obtained by the tool SELI (Shoreline Extraction from Landsat Imagery) is made in order to characterise the medium and long term period changes occurring on beaches. The analysis ...
[ES] El artículo presenta un análisis de la evolución de la línea de costa entre Alcossebre y Orpesa, a partir de fotografías aéreas y ortofotografías, entre 1956 y 2015. La digitialización de 12 líneas de costa ha
permitido ...

[ES] La disposición de múltiples posiciones de la orilla obtenidas de sucesivas imágenes de
satélite de resolución media (como las Sentinel 2), y el reconocimiento de que su
variabilidad está claramente relacionada con ...
[EN] The accuracy and robustness of the shoreline definition from satellite imagery on different coastal types are crucial to adequately characterising beach morphology and dynamics. However, the generic and widespread ...
[EN] This paper evaluates the accuracy of shoreline positions obtained from the infrared (IR) bands of Landsat 7, Landsat 8, and Sentinel-2 imagery on natural beaches. A workflow for sub-pixel shoreline extraction, already ...
[EN] Beach management follows a homogeneous and rigid decision-making process that tries to fulfill expectations assumed from mass tourism without really getting to know the real users' perception. Decisions are usually ...
[EN] The definition of the shoreline position from satellite imagery is of great interest among coastal monitoring techniques. Understanding the reality mapped by the resulting shorelines and defining their accuracy is of ...
[EN] Crop classification based on satellite and aerial imagery is a recurrent application in remote sensing. It has been used as input for
creating and updating agricultural inventories, yield prediction and land management. ...
A high precision geometric method for automated shoreline detection from Landsat TM and ETM+ imagery is presented. The methodology is based on the application of an algorithm that ensures accurate image geometric registration ...

[ES] Las playas son espacios costeros que desarrollan numerosas funciones ambientales. Éstas proporcionan importantes beneficios a la sociedad y a las comunidades costeras, entre las que destacan la función ecológica, el ...
[EN] This paper describes a methodological protocol to project a terrestrial photograph of a coastal area or whatever indicator is contained on it in a georeferenced plane taking advantage of the terrestrial horizon ...
Vaquero Cáceres, Jesús(Universitat Politècnica de València, 2015-05-26)
[ES] El presente estudio tiene dos propósitos claramente diferenciados uno de otro y, a su vez, relacionados entre sí. Uno de ellos está enfocado al estudio de la dinámica de la zona de playa y otro al estudio de la posición ...
[EN] Due to their oceanographic and climatic ecological characteristics, the coastal areas of the Valparaíso Region of Chile are
of great importance for the country's tourist, economic, and environmental development. The ...

[ES] Se presenta un análisis de la evolución reciente de la línea de costa de
los términos municipales de Sagunt y de Canet d’en Berenguer. La principal
novedad es el empleo de imágenes Landsat –con una resolución espacial ...
Tárraga Martínez, Gema(Universitat Politècnica de València, 2015-07-20)
[ES] Durante estas últimas décadas se ha producido una gran explotación urbanística de la zona
costera mediterránea, creando, en algunas áreas un gran deterioro en la misma, sobretodo el los
ecosistemas dunares que existen ...
[EN] Shoreline position can be efficiently extracted with subpixel accuracy frommid-resolution satellite imagery using tools as SHOREX. However, it is necessary to develop procedures for deriving descriptors of the beach ...
