Do you mean hdf5? I extensively used COGs (cloud optimised geotiffs) and NetCDF4 (based on hdf5) at work over the last 10 years. Both have their pros and cons.
The main limitation with geotiff is its pretty much only usable for layered 2D raster data.
NetCDF4 (hdf5) can set up frames of any dimensionality, you can have datetime axes, time series data, 100d ensemble data, etc.
I like FriendlyJordies, appreciate his humour and admire the work he is doing to expose corruption in Australian government. But man, I cannot stand his voice, and his affectation and his mannerisms. I can’t watch his videos anymore, it’s like nails on a chalkboard to me.
