Re: How to add land overlay map to POLYMER processed OLCI Image

Hi Vishnu,
The issue seems to relate to how you are locating your in-situ points in the image, and what you mean by applying CRS projection.
The easiest way to locate a point in the image should be to find the point with the closest lat/lon.
Cheers,
François

Re: MODIS Processing with 250m

Hello, It should be possible to generate 250m L1C products, and then process these with Polymer. I have not tried myself though. I suggest you pass the option "resolution=250" to l2gen in the make_L1C.py script (in the make_L1C function), and try to process the resulting L1C with Polymer. Please let...

Re: How to add land overlay map to POLYMER processed OLCI Image

Hi Vishnu,
I you want to compare Polymer results with a binned image, you should also bin Polymer results, in order to compare the two images in the same grid.
A library such as https://pyresample.readthedocs.io/ may help.
Cheers,
François

Re: OSError: [Errno 24] Too many open files:

Hi Guillaume, It seems that a file is not closed, maybe due to a garbage reference ? If you are doing your processing in a python loop, I would suggest defining a function which processes a single file, if it is not the case already. This can help to avoid garbage references. I hope this helps, chee...

Re: How to run polyner

Hello,
It seems that you tried to attach an image, but it was not attached correctly. Can you try to re-attach your image ?
Thanks,

Re: MSI Inland waters

Hello,

I think this is because you have called your script file "polymer.py", which causes a conflict with the module "polymer". Can you try to rename your script to something else ?
Cheers,

Re: OLCI inland waters

Hello, This is due to the fact that inland waters are flagged in OLCI level1. You can pass options to the Level1_OLCI object, as follows : - Level1_OLCI(..., landmask=None) # disactivate land mask entirely - Level1_OLCI(..., landmask=GSW(agg=8)) where GSW is imported from gsw.py. This will use the G...

Re: Error Processing Landsat-8

Hello, Indeed you need to generate the angles file. The documentation in level1_landsat8.py is a bit succinct, so here it is with some more details : The command to run to generate the angles file is : l8_angles LC08_..._ANG.txt BOTH 1 -b 1 l8_angles is available at: https://www.usgs.gov/land-resour...
