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.
Thank you so much
Yes, you need to resample before.
Thank you so much Peter, if I resampled after applying Sen2cor , there will be different in results?
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.
Is this mean, it is better to change neighbour resampling method to bilinear?
thank you so much
Sorry, this I can’t tell you. You have to decide on your own. This depends on the application.
Try both and select what works better for you.
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?
Thank you so much
Oh, sorry my answer was misleading. I only looked at the error message when replying and haven’t noticed that it is about processing with sen2cor.
Regarding you question:
- This depends on what you want to do afterwards. But in most cases, it is easier to work with a resampled product.
- Sen2cor does not provide resampled outputdata. What the resolution argument means is well explained here: Sen2Cor output resolution - #6 by bdpg
- 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.
