What is the purpose of the Sentinel-2 global mosaic?
The Sentinel-2 Global Mosaic (S2GM) service is a component of the Copernicus Global Land Service providing analysis-ready composites from time-series of Sentinel-2 surface reflectance observations for a variety of land applications.
How many tiles are in the Sentinel 2?
For the processing of the 2019 data, a total of 3513 Sentinel-2 MGRS tiles (10’000 km² each) have been processed, each tile containing multiple observations (roughly every 3 to 5 days) in several spectral channels (6 spectral bands blue to short-wave infrared region). The data for the year 2020 covered 1415 tiles.
Where are the red pixels in the s2gm mosaic?
Shown is a region close to the city of Ptuj in the eastern part of Slovenia. Red pixels in the S2GM product (left) indicate regions with “no data” values. Figure 4: Subset of Figure 3 with (a) S2GM standard mosaic product and (b) the ArtCom mosaic. Red pixels in the S2GM product (left) indicate regions with “no data” values.
How big are the bands of Sentinel 2?
There are 13 Sentinel 2 bands in total. Each band is 10, 20 or 60 meters in pixel size. Sentinel 2 consists of 2 satellites. First came Sentinel 2A which was launched in 2015. Next came Sentinel 2b in 2017. Two additional satellites (Sentinel 2C and 2D) are planned to launch in 2020 and 2021. This will make a total of four Sentinel-2 satellites.
What are the names of the Sentinel 2 satellites?
Sentinel 2 consists of 2 satellites. First came Sentinel 2A which was launched in 2015. Next came Sentinel 2b in 2017. Two additional satellites (Sentinel 2C and 2D) are planned to launch in 2020 and 2021. This will make a total of four Sentinel-2 satellites.
Is the Daily Mosaic the same as the filtered mosaic?
However, I was expecting that the resulting imageCollection (daily) would have less images than the original filtered collection (s2), as these are mosaicked together by date and orbit, but the number of images in each collection is the same.
How to make a daily Mosaic in Earth Engine?
I’m following the answer on Filter out “incomplete” Sentinel-2 images in Earth Engine to make daily mosaics of Sentinel 2 images.
