Aggregates of floating materials detected in North Adriatic six Sentinel-2 scenes August 2020 have been investigated. Most the were identified by chlorophyll red edge and consisted vegetal materials, probably conveyed rivers exchanged with lagoons. Traces marine litter looked for spectral anomalies Red Edge bands, assuming changes pixels where was mixed materials. About half patches unclassifie...

Satellite remote sensing is a useful tool for estimating crop variables, particularly Leaf Area Index (LAI), which plays pivotal role in monitoring development. The goal of this study was to identify the optimal Sentinel-2 bands LAI estimation and derive Vegetation Indices (VI) that are well correlated with LAI. Linear regression models between time series imagery field-measured showed Band-8A—...

Cotton is an important economic crop, but large-scale field extraction and estimation can be difficult, particularly in areas where cotton fields are small discretely distributed. Moreover, soybean cultivated together some areas, further increasing the difficulty of extraction. In this paper, innovative method for area using Sentinel-2 images, land use status data (LUSD), survey proposed. Three...

Corn (Zea mays L.) nitrogen (N) management requires monitoring plant N concentration (Nc) with remote sensing tools to improve use, increasing both profitability and sustainability. This work aims predict the corn Nc during growing cycle from Sentinel-2 Sentinel-1 (C-SAR) sensor data fusion. Eleven experiments using five fertilizer rates (0, 60, 120, 180, 240 kg ha−1) were conducted in Pampas r...

This study investigated the utility of Sentinel-2 spectral data for estimating leaf area index (LAI), and canopy chlorophyll content maize at different growth stages. Vegetation indices based on visible-near infrared red-edge regions spectrum were computed from imagery acquired within one or two days field collection. Results showed that green (CIgreen) (CIred-edge), using variant centred 705 n...

Biomass burning is a global phenomenon and systematic burned area mapping is of increasing importance for science and applications. With high spatial resolution and novelty in band design, the recently launched Sentinel-2A satellite provides a new opportunity for moderate spatial resolution burned area mapping. This study examines the performance of the Sentinel-2A Multi Spectral Instrument (MS...

In the present study, temporal and spatial dynamics of post-fire recovery different Mediterranean vegetation types during three years after fire event were analyzed, according to severity categories, integrating use Synthetic Aperture Satellite Radar (SAR) (Sentinel-1) optical (Sentinel-2) image time series. The results showed that forest species shrub/herbaceous are adapted fire, with high eff...
