Which is the best JP2 image for Sentinel 2?
You can simply use the TCI.jp2 file that its included in the SAFE.zip files. Note that these files are not available in S2 files before October 2016 -scale 0 4096 is a reasonable value for Sentinel-2 scenes and afaik also used for the TCI.jp2 images.
How to convert raw Sentinel 2 to 8bit?
There are 2 parts of the problem. The first is that you want to convert from 16 bits to 8bit, and the -scale option of gdal_translate does it, as mentioned in the previous answer.
How to create RGB images from L1C data?
I want to create “visually appealing” RGB images from Sentinel-2 L1C data in a standardized manner. Obviously, this starts with extracting the bands 4, 3, and 2, which correspond to the Red, Green, and Blue channels of the electromagnetic spectrum.
How to visualize Sentinel 2 data in snap?
Finally, one of the interesting gems in SNAP is the “Spectrum View” tool, found under the “Optical” tab, which builds spectral plots of the image at the location of the mouse pointer: Spectrum View tool in SNAP. Dimensionless “dl” units (thanks Jens for the information on this!). Happy working with Sentinel 2 data!
Which is the best JP2 file for GeoTIFF?
With stats from a subset where there are no “NoData” (top left of your image), this give the final result. You can see that the range is about half of the “safe” range, which means that you have twice as much contrast: You can simply use the TCI.jp2 file that its included in the SAFE.zip files.
How to train inception-v3 with raw Sentinel?
A scene image will be cut into smaller patches (maybe 64×64) and will be classified by CNN ( crop or non-crop ). I use this dataset to train Inception-v3 model. The dataset contains 64×64 RGB images with 10m spatial resolution. More info about merged.tif There are 2 parts of the problem.
Which is the best scale for Sentinel 2?
-scale 0 4096 is a reasonable value for Sentinel-2 scenes and afaik also used for the TCI.jp2 images. Lower the 4096 if you want to receive a lighter result.
Is it possible to layer stack all 13 Sentinel 2 bands?
Is it possible to layer stack all 13 Sentinel 2 bands or can I only layer stack those that are the same resolution (so for example the blue, green red and NIR bands). I have a very large area of interest so will have many sentinel images.

Is there any way to open Sentinel 2 JPEG2000 file?
Is there any way I can open Sentinel 2 JPEG2000 file ( .jp2) using R? Or more specifically with the {raster} package in R? I keep getting the Error message that .jp2 is: not recognised as a supported file format.
Is there a way to read Sentinel 2 data?
The latest version of GDAL (2.1) has the ability to read Sentinel 2 data (see http://gdal.org/frmt_sentinel2.html) in the SAFE file structure. It reads as sub-datasets so you need to run gdalinfo first on the main XML file to show all subdatasets (one for each resolution and UTM zone) then to select the one you want.
What is the purpose of the Sentinel 2 mission?
Sentinel-2 is an observation mission developed by the European Space Agency to monitor the surface of the Earth official website . Sets of images are taken of the surface where each image corresponds to a specific wavelength.
