Reproject Sentinel-3 OLCI images

[vebjorn....@gmail.com]

Hi

Im fairly new to python, and would like to process remote sensing data. I came across satpy, which seems to be the perfect package for that. I would like to reproject a Sentinel-3 OLCI image with the crs epsg:3575. Its for sea ice montioring in artic regions. If anyone could provide an example script and workflow that would be great. 

Thanks,

Vebjørn

Hej Vebjørn,

Welcome on board!

There is an example on how to process OLCI data with satpy here:

https://github.com/pytroll/pytroll-examples/blob/master/satpy/OLCI%20L1B.ipynb

The reprojection is not provided in this example, but look at other examples in the repo for that.

As for the workflow, if you mean continuous processing of the data as it comes in, the trollflow and trollflow-sat packages can be helpful.

Best regards,

Martin

Hi

I have seen the example, but as you say the reprojection is not included. I would like to know exactly how to do the reprojection, as this is what Im having trouble with. By workflow I mean the exact code, line by line preferably with explanation/comments. 

Best,

Vebjørn

Hi,

I updated the olci example with resampling and a little more text. Feel free to complement this tutorial!

Hi

Thank you. It would also be nice if you added the final step where you save/write the file.

Regards,

Vebjørn

Before the example is updated (might not be, as there are other examples
that already show this):

fname = "/path/to/somewhere/image.tif"
newscn.save_dataset(composite, filename=fname)
