UTFGrid

UTFGrid is a specification for rasterized interaction data. As of version 1.2, it was removed from incubation in the MBTiles Specification and split into its own repository.

See CHANGELOG.md for per-version changes.

Examples

The Visible Map demo is an example of client-side interaction using UTFGrid encoded features.

Glower shows how to do feature highlighting.

Mapnik's grid_renderer is an example of code that can encode spatial features into UTFGrid.
