toasty

toasty is a Python library that helps you create “tile pyramids” from astronomical image data as used in the TOAST format. These multi-resolution maps can be viewed in software such as the AAS WorldWide Telescope.

toasty was originally written by Chris Beaumont, benefited from contributions by Clara Brasseur (Space Telescope Science Institute), and is currently maintained as part of the AAS WorldWide Telescope project.
