How do I convert a multiband raster to a NetCDF file with a time variable?

The netcdf format is new to me. I have created a multiband raster with 50 bands. Each band contains values for 1 day. My workflow looks like this:

 

imageThe sampler to the left is for testing only and lets 7 bands go through. The listbuilder creates a list of values for the 'days_since' variable. I want to use these values in the writer for the 'netcdf_band{}.coordinate_variable{}' port.

imageHow do I apply this as a list? At the moment I have to apply them individually day for day in the attribute manager before the writer.

imageThis works but is obviously not scalable. Any help in this matter would be much appreciated - I have thousands of bands to include! :)

Hi @dean.mcgowan​ ,

I think you can create the list attribute "netcdf_band{}.coordinate_variable{0}" with the RasterBandCombiner, if you rename "_day" to "coordinate_variable{0}" with AttributeRenmaer or AttributeManager before combining the raster bands.

Why not inspect features with Visual/Data Preview and Feature/Record Information before writing them into a destination dataset?

Cheers, That sorted the issue out for me!
