We are creating cog files using our code that takes as input any raster, tiles it add overviews and rearrange the tif to be a cog.
For doing so we are using rasetio shutils copy and rasterio build_overview.
The source rasters that we are working on have nodata
We did a variant of code in which we prior for creating the overviews we also created Band Mask
