Super-resolving multiresolution images with band-independant geometry of multispectral pixels [PDF]

open access: yes, 2016
A new resolution enhancement method is presented for multispectral and multi-resolution images, such as these provided by the Sentinel-2 satellites. Starting from the highest resolution bands, band-dependent information (reflectance) is separated from ...

Tropical Forest Top Height by GEDI: From Sparse Coverage to Continuous Data

open access: yesRemote Sensing, 2023
Estimating consistent large-scale tropical forest height using remote sensing is essential for understanding forest-related carbon cycles. The Global Ecosystem Dynamics Investigation (GEDI) light detection and ranging (LiDAR) instrument employed on the ...

A combination of Sentinel-1 RADAR and Sentinel-2 multispectral data improves classification of morphologically similar savanna woody plants

open access: yesEuropean Journal of Remote Sensing, 2022
The co-existence of diverse plant forms in densely vegetated savanna environments presents a challenge when mapping species diversity using single remotely sensed data type that carries either optical or structural information.

Benchmark of machine learning methods for classification of a Sentinel-2 image [PDF]

open access: yes, 2016
Thanks to mainly ESA and USGS, a large bulk of free images of the Earth is readily available nowadays. One of the main goals of remote sensing is to label images according to a set of semantic categories, i.e. image classification.

Fusion of Sentinel-1 data with Sentinel-2 products to overcome non-favourable atmospheric conditions for the delineation of inundation maps

open access: yesEuropean Journal of Remote Sensing, 2020
729Sentinel-1 data are an alternative for monitoring flooded inland surfaces during cloudy periods. Supervised classification approaches with a single-trained model for the entire image demonstrate poor accuracy due to confusing backscatter conditions of

Mapping Mediterranean seagrasses with Sentinel-2 imagery [PDF]

open access: yesMarine Pollution Bulletin, 2018
Mediterranean seagrasses have been hailed for their numerous ecosystem services, yet they are undergoing a decline in their coverage. The major complication with resolving this tendency is the sparsity of data on their overall distribution. This study addresses the suitability of the recently launched Sentinel-2 satellite for mapping the distribution ...

Oil Spill Detection Analyzing “Sentinel 2“ Satellite Images: A Persian Gulf Case Study [PDF]

open access: yes, 2018
Oil spills near exploitation areas and oil loading ports are often related to the ambitions of governments to get more oil market share and the negligence at the time of the loading in large tankers or ships.
