Satellite images Sentinel-2 Hamburg
Description
Within the Copernicus programme, the European Space Agency (ESA) provides satellite data from the Sentinel (the Guardian) missions free of charge. The LGV prepares the data for easier use on a quarterly basis.
Original satellite data can be obtained via the national platform
Code-DE (Copernicus Data and Exploitation Platform – Germany).
Data base:
— Sentinel @-@ 2 L2A: Multispectral, atmospheric corrected data
— Georeferenced mosaic
— Tile @-@ Number: 25
— Tile @-@ Size: 8 km x 8 km
— Tile @-@ Selection: Timeliness and degree of cloud cover
— Colour representation: RGB, CIR, NDVI
— Soil resolution: 10 m
— Colour depth: 8 bit
RGB (Red Green Blue):
The band combination of red (B4), green (B3) and blue (B2) mimics human color perception. Healthy vegetation becomes green, urban areas will be white/grey and water areas will be 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 shown reddish. Urban areas appear cyan-blue/grey and water areas dark blue.
NDVI (Normalised Difference Vegetation Index):
The NDVI is a commonly used index used to assess vegetation. It is calculated from the bands Near Infrared (B8) and Red (B4):
NDVI = (NIR-Red)/(NIR+Red)
