Exporting .nc using to_netdcf with open_rasterio() failes exporting all Attributes #3776
Description
MCVE Code Sample
image = '/home/user/Desktop/LE07_L1TP_192028_20100208_20161217_01_T1_AOI_ITA_LS_TILE_192028.tif'
data = xr.open_rasterio(image)
data.to_netcdf('/home/elisavet/Desktop/LE07_L1TP_192028_20100208_20161217_01_T1_AOI_ITA_LS_TILE_19202.nc')Expected Output
The output should keep all attributes from the original file which are the following:
<xarray.DataArray (band: 4, y: 409, x: 645)>
[1055220 values with dtype=float64]
Coordinates:
* band (band) int64 1 2 3 4
* y (y) float64 46.95 46.94 46.94 46.93 ... 45.13 45.12 45.12 45.12
* x (x) float64 10.59 10.6 10.6 10.61 10.61 ... 13.47 13.48 13.48 13.49
Attributes:
