What is MBTiles?
MBTiles is a SQLite-based tile archive format that stores tiled map content in one portable file for offline and packaged distribution workflows.
MBTiles became popular because it lets teams ship a tile dataset as one file instead of a directory of many small tiles, which is useful for mobile, desktop, and field deployments.
It works well when the objective is cached viewing or packaged delivery, but it is not the same thing as a canonical feature-editing dataset used for attribute cleanup and spatial QA.
