The four operational modes offered by Sentinel-1 are: [11] [16] [17] Strip Map (SM) Mode, which features 5-by-5-metre (16 by 16 ft) spatial resolution and an 80 km (50 mi) swath. The sole uses of SM are to monitor small islands as well as emergency management for extraordinary events upon request.

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 ...
Sentinel-1A is a European radar imaging satellite launched in 2014. It is the first Sentinel-1 satellite launched as part of the European Union 's Copernicus programme . The satellite carries a C-band Synthetic Aperture Radar which will provide images in all light and weather conditions.
Spatial resolution is defined as the pixel size of an image representing the size of the surface area (i.e. m 2) ... Sentinel-1 (SAR imaging), Sentinel-2 ...
Sentinel-1B was a European radar imaging satellite launched on 25 April 2016. It is the second of two original satellites in the Sentinel-1 constellation, part of the European Union's Copernicus programme on Earth observation. The satellite carries a C-SAR sensor, capable of providing high-resolution imagery regardless of weather conditions.
Synthetic-aperture radar (SAR) is a form of radar that is used to create two-dimensional images or three-dimensional reconstructions of objects, such as landscapes. [1] SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional stationary beam
Sentinel-2 provides high-resolution optical imaging for land services (e.g. imagery of vegetation, soil and water cover, inland waterways and coastal areas). [21] Sentinel-2 will also provide information for emergency services. All satellites launched aboard Vega rockets from Centre Spatial Guyanais. Sentinel-2A, successfully launched on 23 ...
