PMTiles/README.md

PMTiles

PMTiles is a single-file archive format for tiled data. A PMTiles archive can be hosted on a commodity storage platform such as S3, and enables low-cost, zero-maintenance map applications that are "serverless" - free of a custom tile backend or third party provider.

For those familiar with Cloud Optimized GeoTIFFs - PMTiles uses similar techniques, but is specific to Z/X/Y tiles and can store vector data.

Compatible Storage Providers

PMTiles files require servers to support HTTP byte serving as well as CORS. It's been tested with:

• Amazon Web Services S3
• Google Cloud Storage
• Microsoft Azure
• DigitalOcean Spaces
• Backblaze B2
• Your own HTTP server

Amazon Web Services

• ACL Level
• CORS Policy

Google Cloud

Azure

• HEAD requests for ranges return 200 instead of 206
• Configuration through Web Portal

DigitalOcean Spaces

Backblaze B2
