Satellite images Sentinel-2 Hamburg

The European Space Agency (ESA) provides free of charge satellite data from the Sentinel missions within the Copernicus programme. The LGV prepares the data on a quarterly basis for easier use.

Originally, the satellite data can be accessed via the national platform.
CODE-DE (Copernicus Data and Exploitation Platform – Germany).

Data basis:
Sentinel-2 L2A: Multispectral, atmospherically corrected data
Georeferenziertes Mosaik
Kachel-Anzahl: 25
Kachel-Größe: 8 km x 8 km
Kachel-Auswahl: Timeliness and degree of cloud cover
Farbdarstellung: RGB, CIR, NDVI
Bodenauflösung: 10m
Farbtiefe: 8 bit

RGB (Red Green Blue):
The band combination of red (B4), green (B3) and blue (B2) reproduces human color perception. Healthy vegetation becomes green, urban areas become white/grey and water areas become blue, depending on the turbidity.

CIR (Color Infrared):
The band combination of near infrared (B8), red (B4) and green (B3) highlights the vegetation. This reflects particularly strongly due to the chlorophyll content of the plants in the near infrared range and is reddish. Urban areas appear cyan blue/grey and water areas dark blue.

NDVI (Normalized Difference Vegetation Index):
The NDVI is a commonly used index used to estimate vegetation. It is calculated from the bands Near Infrared (B8) and Red (B4):
NDVI = (NIR-Red)/(NIR+Red)
