How to specify BLOCKSIZE in to_raster()?

[rsignell-usgs]

I have an xarray dataarray, and I can write to COG using rioxarray using the default 512x512, but then I tried to specify the blocks to be 1024 instead of 512. I thought this would just be:

da.rio.to_raster(raster_path=cog, driver="COG", profile_kwargs={'BLOCKSIZE':1024})

but it just seems to ignore it and generates 512x512 again, so what did I do wrong?

The full notebook is here (which is supposed to demonstrate how to work with big geotiff using Dask):

profile_kwargs are keyword arguments. So, you would input them like so:

da.rio.to_raster(raster_path=cog, driver="COG", blocksize=1024)

Here's the updated notebook! Please let me know if you see any improvements that could be made!
