Closed rkaiser0324 closed 1 year ago

Running the script yields this repeated error:

Yes, it might be because the warp crosses the anitmeridian. I haven't found GDAL to be particularly scrutible.

lanceberc commented 1 year ago

Also, the call to warp causes gdal to emit a "sidecar" file that is removed by paccup_overlay.py. Telling gdal to not emit sidecars causes warp to fail.

At one point reprojection was implemented with cartopy instead of gdal but it was much slower and used far more memory. See https://github.com/lanceberc/GOES/blob/master/GOES_Cartopy.ipynb.

If it doesn't have any practical effect this error should probably be caught and suppressed.

lanceberc commented 1 year ago

It sure would be nice if GDAL raised an exception, but it doesn't. It doesn't hurt anything and doesn't affect correctness.

Ok closing.
