Damaged Road Sentinel-1
SENTINEL-1 SLC

Sentinel-1 SLC

Level-1 Single Look Complex (SLC) products consist of focused SAR data, geo-referenced using orbit and attitude data from the satellite, and provided in slant-range geometry. Slant range is the natural radar range observation coordinate, defined as the line-of-sight from the radar to each reflecting object. The products are in zero-Doppler orientation where each row of pixels represents points along a line perpendicular to the sub-satellite track. Read more

Water Flood Sentinel-1
SENTINEL-1 GRD

Sentinel-1 GRD

Level-1 Ground Range Detected (GRD) products consist of focused SAR data that has been detected, multi-looked and projected to ground range using the Earth ellipsoid model WGS84. The ellipsoid projection of the GRD products is corrected using the terrain height specified in the product general annotation. The terrain height used varies in azimuth but is constant in range (but can be different for each IW/EW sub-swath). Read more

SENTINEL-2 LAI

Sentinel-2 LAI

The Leaf Area Index is defined as half the total area of green elements of the canopy per unit horizontal ghoeken area. The satellite-derived value corresponds to the total green LAI of all the canopy layers, including the understory which may represent a very significant contribution, particularly for forests. Practically, the LAI quantifies the thickness of the vegetation cover. Read more

SENTINEL-2 fAPAR

Sentinel-2 fAPAR

The Fraction of Absorbed Photosynthetically Active Radiation quantifies the fraction of the solar radiation absorbed by live leaves for the photosynthesis activity. Then, it refers only to the green and alive elements of the canopy. The FAPAR depends on the canopy structure, vegetation element optical properties, atmospheric conditions, and angular configuration. To overcome this latter dependency, a daily integrated FAPAR value is assessed. Read more

SENTINEL-2 FCOVER

Sentinel-2 FCOVER

The Fraction of Vegetation Cover corresponds to the fraction of ground covered by green vegetation. Practically, it quantifies the spatial extent of the vegetation. Because it is independent from the illumination direction and it is sensitive to the vegetation amount, fCover is a very good candidate for the replacement of classical vegetation indices for the monitoring of ecosystems.

Sentinel2 NDVI
SENTINEL-2 NDVI

Sentinel-2 NDVI

The Normalized Difference Vegetation Index is a simple and effective vegetation index to quantify the vegetation amount. It is an indicator of the greenness of the biomes, little scale dependant and is closely linked to the FAPAR. Read more

SENTINEL-3 SYN

Sentinel-3 SYN

The combination of the OLCI and SLSTR instruments yields SYN products, providing continuity with SPOT VEGETATION. The primary objective of the SYN products is land monitoring, providing information related to worldwide vegetation status and contributing to the study of climate change. Read more

This application contains a simple classification of your municipality based on recent images taken by the Sentinel-2 satellites. It is an example of how Sentinel data can be used in an application. As mentioned it is only an example, it does not concern an official classification.
