Tiered local storage: Working with aerial imagery comes with some very enjoyable technical problems around storage. I wrote a small blog post about the storage system of Mapterhorn. Read more here: https://oliverwipfli.ch/tiered-local-storage-2026-06-08/

Mapterhorn might grow over time to more than 5 TiB total size, i.e., larger than typical object store size limits, this is why the tile pyramid broken into a zoom 0 to 12 subpyramid plus some zoom 13+ subpyramids. Each such subpyramid is a pmtiles file and the size is expected to be around 1 TiB.

@behdad Thanks for that amazing demo. Text looks very nice on my phone. But on my computer screen which has 1x pixel density small text looks a little not so good. Are there any tricks to improve rendering on lower density screens?

@behdad@typo.social Do you think the Slug Library could be used to create a renderer for COLRv1 fonts like Google's Noto Color Emoji font?

@tdurand@mapstodon.space OK thanks for the feedback. Do RSS feeds usually include the content? Would that be a good addition from your point of view?
