To generate an MBTiles file with PNG image map tiles from the Humanitarian Data Model style, follow this steps (on Mac OS X).

Part 1:

Use this workflow to generate a vector tile based map in Mapbox Studio from an osm.pbf file. https://gist.github.com/aaronpdennis/a53f9afb8ef24d499e96

Part 2:

Install tl.

Building and Updating a Global HDM Vector Tile Source from OSM Data

The Mapbox Studio style hdm-style.tm2 is a humanitarian map design that relies on three vector tile sources, two of which are hosted and served by Mapbox:

1. Mapbox Streets
2. Mapbox Terrain
3. Humanitarian Data Model vector tiles

The third source is the focus of this writeup. Currently, hdm-style.tm2 uses a hand-processed, non-updating snapshot of HDM vector tiles for small subregions of the world. This gist explains in rough psuedocode and theory how you could set up a HDM vector tiles source that would update hourly (or minutely or daily) from the OSM database and cover the entire planet.
