Castra Oresbi: um assentamento militar romano na Serra do Marão?
(CITCEM – Centro de Investigação Transdisciplinar «Cultura, Espaço e Memória», 2017)Lino Tavares Dias e António Baptista Lopes referem a existência de um acampamento militar romano no alto da Serra do Marão, de nido por um recinto rectangular, ao qual estaria associado uma torre de planta quadrangular. ... -
Del oppidum indígena a la ciudad romana. Evolución del paisaje de Segisamo (Sasamón, Burgos, España) a través de la fotografía aérea. Datos de la prospección aérea de 2019
(Universitat d'Alacant, 2020)Desde 2008 hemos desarrollado un amplio programa de investigación en la comarca del Odra-Pisuerga y tierras de Amaya que tiene como objetivo ahondar en los procesos fundamentales que nos permitan conocer el cambio cultural, ... -
Efficient multitemporal change detection techniques for hyperspectral images on GPU
(2018)Hyperspectral images contain hundreds of reflectance values for each pixel. Detecting regions of change in multiple hyperspectral images of the same scene taken at different times is of widespread interest for a large ... -
Estimación del área basimétrica en masas maduras de Pinus sylvestris en base a una única medición del escáner láser terrestre (TLS)
(Sociedad Española de Ciencias Forestales (SECF), 2019)El láser escáner terrestre (TLS) ha surgido como un nuevo dispositivo de tecnología LiDAR con un gran potencial para ser implementado en inventarios forestales (IIFF). En este trabajo se ha desarrollado un algoritmo con ... -
Estimating biomass of mixed and uneven-aged forests using spectral data and a hybrid model combining regression trees and linear models
(Italian Society of Silviculture and Forest Ecology (SISEF), 2015)The Sierra Madre Occidental mountain range (Durango, Mexico) is of great ecological interest because of the high degree of environmental heterogeneity in the area. The objective of the present study was to estimate the ... -
Evaluation of Radiometric and Atmospheric Correction Algorithms for Aboveground Forest Biomass Estimation Using Landsat 5 TM Data
(MDPI, 2016-04-29)Solar radiation is affected by absorption and emission phenomena during its downward trajectory from the Sun to the Earth’s surface and during the upward trajectory detected by satellite sensors. This leads to distortion ... -
Exploring the Registration of Remote Sensing Images using HSI-KAZE in Graphical Units
(2019)Registration of hyperspectral remote sensing images is a common task in many image processing applications such as land use classification, environmental monitoring and change detection. The images to be registered present ... -
Extended Anisotropic Diffusion Profiles in GPU for Hyperspectral Imagery
(IEEE, 2019)Morphological profiles are a common approach for extracting spatial information from remote sensing hyperspectral images by extracting structural features. Other profiles can be built based on different approaches such as, ... -
Extreme wave height events in NW Spain: a combined multi-sensor and model approach
(MDPI, 2018)The Galician coast (NW Spain) is a region that is strongly influenced by the presence of low pressure systems in the mid-Atlantic Ocean and the periodic passage of storms that give rise to severe sea states. Since its ... -
Following the Roman Army between the Southern Foothills of the Cantabrian Mountains and the Northern Plains of Castile and León (North of Spain): Archaeological Applications of Remote Sensing and Geospatial Tools
(MDPI, 2020)Sixty-six new archaeological sites have been discovered thanks to the combined use of different remote sensing techniques and open access geospatial datasets (mainly aerial photography, satellite imagery, and airborne ... -
FORTLS: An R Package for Processing TLS Data and Estimating Stand Variables in Forest Inventories
(MDPI, 2021)Terrestrial Laser Scanning (TLS) enables rapid, automatic, and detailed 3D representation of surfaces with an easily handled scanner device. TLS, therefore, shows great potential for use in Forest Inventories (FIs). However, ... -
Fourier–Mellin registration of two hyperspectral images
(Taylor & Francis, 2017-03-21)Hyperspectral images contain a great amount of information which can be used to more robustly register such images. In this article, we present a phase correlation method to register two hyperspectral images that takes ... -
From Land Cover to Land Use: A Methodology to Assess Land Use from Remote Sensing Data
