The atmospheric correction is competed using Sen2COR, i selected 10m resolution. I tried to save as the output or even one band in Tiff format to can open it in arc and check the final resolution of the output, but I got this error.
Is this mean i need to resample the output to 10 m.
A bit but if you use nearest neighbour resampling you introduce no new artificial values as with interpolating resampling, like bilinear interpolation.
However, the difference should be small in both cases.
Switching to a format with more complete metadata support and capable of handling bands with different resolutions such as netcdf4-cf may be easier than resampling, and will use less storage space.
I resampled the image first as you recommended me but Sen2cor did not work for the resampled image.
So i applied Sen2Cor first then i resampled the image and it worked well.
I have three questions 1- Do i need to resample the image after run Sen2cor or not? 2- if we need to resample it , so in sen2cor process , i already select 10 m resolution, this resolution mean what? 3- How to check the resolution of the sen2cor outputs to make sure that all bands are 10 m?
Sen2cor outputs are all at 10m if you provide the --resolution 10 argument. Nut then you only have the 4 bands which are already in the L1C at 10m resolution.
