Re: how to run the polymer

Hi, It seems that the download of "auxdata/common/no2_climatology.hdf" has failed, could you try to remove this file and try again ? By the way, there was a letter "i" missing in the filename you mentioned. Concerning the processing of Landsat8 files : * You need to provide a directory name, not a t...

Re: What is Bitmask 2112

Dear Vishnu, Bitmask is coded in binary, where each bit represents a flag, as coded in bitmask's attributes, from LAND=1=2^0 to INCONSISTENCY=2048=2^11. Thus 2112 = 64+2048 = THICK_AEROSOL+INCONSISTENCY It is recommended to remove pixels where any of the first eleven bits is raised, thus where "bitm...

Re: Geo-coordinates of Sentinel-2 results

Great! Good to read that it solves the issue. I will integrate this modification in further Polymer releases. Just a minor comment: in python3 you would have to use XDIM//2 to stay with integers, XDIM/2 gives a float. But I don't expect that it should affect the results - maybe the performance ? But...

Re: Geo-coordinates of Sentinel-2 results

Hi Martin, Thanks for the detailed feedback ! You are right, it is clear Polymer is wrong in how it reads the lats/lons. As you say, the coordinates of the centre of the north east pixel should not be the same at different resolutions. Looking at the code (method init_latlon in level1_msi.py), it is...

Re: how to run the polymer

I doubt your command has succeeded, because the command should be "make", in the directory containing the makefile, not "make ./polymer4.13/".

Re: how to run the polymer

Dear Ding,
You need to compile the program first, using the command "make".
More information can be found in the file README.md.
Cheers,

Re: how to run the polymer

Hi,
I can not provide help about IDLE, but if you provide me with more information about your issue with polymer_cli.py, I would be happy to help.
Cheers,
