- Style via TileMill
- Export to .mbtiles (2 things included: raster images and UTFGrid teaser)
- 3 Implementation Options
- Expensive if very large
- Upload .mbtiles to MapBox and a TileJSON is created for you (bundles raster images and UTFGrid teaser together)
- MBTiles server implementation like TileStream (Tested: Mac OS X 10.6, Ubuntu 10.04, Ubuntu 11.04, Dependency: node 0.8.x, At least 613MB memory, Ubuntu install guide or here or VM or gotchas)
- Server needed
- Would need to examine options within this
- Potentially not dealing with splitting mbtiles (raster images and UTFGrid teaser)
- I believe you have to make a TileJSON yourself
- Thematic Mapping Blog Tutorial - uses mbtiles-php
- Server needed
- Last hack resort help
- Deal with splitting mbtiles (raster images and UTFGrid teaser)
- handle
gzipencoding viagzipormbutillibraries, usewax, make sure grid coordinates are like OSM
- handle
- Tiles on disk are notoriously difficult to manage.
- Requires installing
Git,Python >= 2.6 - I believe you have to make both a TileJSON and gridLayer yourself

- Build Site (HTML / CSS / JavaScript)
- Upload Site
UTFGrid example and docs - is how Internews Afghanistan map created JSON objects based on mouseover. Baked into TileMill as the teaser interactivity.
- Use create_utfgrids as the mbutil built-into TileMill hasn't been updated to the current Mapbox.js library
- If using mbutil to create UTFGrids, must use 0.2.0 version and add
--grid_callback=""
MBTiles - SQLite spec to query individual rendered map tiles exported from TileMill, has 2 elements: raster tile imagery and UTFGrid interactivity. Mapbox.js automates display of teaser interactivity using tooltips via L.mapbox.gridLayer(). But MBTiles is just a SQLite specification not actually storing the imagery but a string reference to it. Read more here...
- If Option 2 or 3, what how does
L.mapbox.gridLayer()in Mapbox.js work? Is it a big JSON that returns little JSONs (i.e. what I saw from Internews)? How are they divided?
- I'm under the impression that it would be possible to pull out the UTFGrid info and have it appear wherever you want it to, not appearing in the status quo tooltip...
- gridLayer question and spec
2 Sources of Interactivity (GeoJSON and TileJSON) in 1 Panel will be very difficult to do.
