MBTiles 1.0
Abstract
MBTiles is a specification for storing tiled map data in SQLite databases for immediate
usage and for transfer. MBTiles files, known as tilesets, must implement the
specification below to ensure compatibility with devices.
Database Specifications
Tilesets are expected to be valid SQLite databases of version 3.0.0 or higher. Only core
SQLite features are permitted; tilesets cannot require extensions.
Database
Note: the schemas outlined are meant to be followed as interfaces. SQLite views that
produce compatible results are equally valid. For convenience, this specification refers
to tables and virtual tables (views) as tables.
