[gdal-dev] Geostationary Projection with microradians

[Zachary Flamig]

Hi all,

The GOES-16 satellite has started delivering full disk netcdf files that conform to a new portion of the CF standard: https://cf-trac.llnl.gov/trac/ticket/72 <https://cf-trac.llnl.gov/trac/ticket/72>
Unfortunately, they choose to use units of micro-radians instead of meters so it doesn’t appear the files are immediately compatible with GDAL.

It is rather straight forward to convert from the radians to meters given the height of the satellite (which is included in the projection information). Would this be something appropriate for GDAL to convert or is it more of a PROJ4 problem?

I’ve uploaded some example netcdfs here: https://www.dropbox.com/s/ell4iy0hiwzquqy/fulldisk_wv.zip?dl=0 <https://www.dropbox.com/s/ell4iy0hiwzquqy/fulldisk_wv.zip?dl=0>
The data is tiled into 4 separate netcdfs that can be combine for the full disk image.

Cheers,
Zac
