Sentinel-2 is an Earth observation mission from the Copernicus Programme that acquires optical imagery at high spatial resolution (10 m to 60 m) over land and coastal waters. The mission's Sentinel-2A and Sentinel-2B satellites were joined in orbit in 2024 by a third, Sentinel-2C, and in the future by Sentinel-2D, eventually replacing the A and ...
An ecological study used 16 ortho-rectified Landsat images to generate a land cover map of Mozambique's mangrove forest. The main objective was to measure the mangrove cover and above ground biomass on this zone that until now could only be estimated, the cover was found with 93% accuracy to be 2909 square kilometers (27% lower than previous ...
A composite of Ireland's land cover derived from Sentinel-1A data. There are a wide range of applications for the data collected via the Sentinel-1 mission, including marine and land monitoring, emergency response to environmental disasters, and economic applications. A major goal of the mission was to provide C-Band SAR data. [14]
The remainder of the area has a mixed hardwood-softwood cover with some small pockets of white pine between ledges near the northern boundary. Good views may be obtained from the top of Sentinel and Pitchoff Mountains, but forest cover restricts the view of Kelburn Mountain, Stewart Mountain, Slide Mountain and Black Mountain. There is an ...
A supervised classification is a system of classification in which the user builds a series of randomly generated training datasets or spectral signatures representing different land-use and land-cover (LULC) classes and applies these datasets in machine learning models to predict and spatially classify LULC patterns and evaluate classification accuracies.

A Sentinel-3 image shows true colour (left) and land temperature (right) during the 2021 Eurasia winter heat wave. SLSTR (Sea and Land Surface Temperature Radiometer) determines global sea-surface temperatures to an accuracy of better than 0.3 K (0.3 °C; 0.5 °F). It measures in nine spectral channels and two additional bands optimised for ...
Copernicus is the Earth observation component of the European Union Space Programme, managed by the European Commission and implemented in partnership with the EU member states, the European Space Agency (ESA), the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), the European Centre for Medium-Range Weather Forecasts (ECMWF), the Joint Research Centre (JRC ...
