The added value of stratified topographic correction of multispectral images
Satellite images in mountainous areas are strongly affected by topography. Different studies demonstrated that the results of semi-empirical topographic correction algorithms improved when a stratification of land covers ... -
Assessment of atmospheric correction methods for Sentinel-2 images in Mediterranean landscapes
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 ... -
Automatic detection of uprooted orchards based on orthophoto texture analysis
Permanent crops, such as olive groves, vineyards and fruit trees, are important in European agriculture because of their spatial and economic relevance. Agricultural geographical databases (AGDBs) are commonly used by ... -
Desarrollo de productos avanzados para la misión SEOSAT/Ingenio
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 ... -
Estrategia para la verificación de declaraciones PAC a partir de imágenes Sentinel-2 en Navarra
En junio de 2018, la Comisión Europea aprobó una modificación de la Política Agraria Común (PAC) que, entre otros aspectos, plantea el uso de imágenes del programa Copernicus para verificar que las declaraciones presentadas ... -
Evaluación multitemporal de métodos de corrección topográfica mediante el uso de imágenes sintéticas multiespectrales
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 ... -
Evaluation of topographic correction algorithms on satellite images
Este trabajo contribuye al previamente limitado conocimiento acerca del rendimiento de los métodos de corrección topográfica proponiendo una nueva metodología de evaluación basada en imágenes sintéticas. Esta nueva metodología ... -
Inter-comparison of atmospheric correction methods on Sentinel-2 images applied to croplands
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 ... -
Multi-criteria evaluation of topographic correction methods
In the last decades, several topographic correction methods (TOC) have been proposed, but there is not an agreement on the best method. Furthermore, different evaluation criteria have been used in the past, and there is ... -
Multitemporal evaluation of topographic correction algorithms using synthetic images
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 ... -
Synthetic images for evaluating topographic correction algorithm
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 ... -
Validation of a simplified model to generate multispectral synthetic images
A new procedure to assess the quality of topographic correction (TOC) algorithms applied to remote sensing imagery was previously proposed by the authors. This procedure was based on a model that simulated synthetic scenes, ...
