Equal-area world tile-grid layout

A statebins-style equal-area tile layout: one square per country, positioned on a row/col grid derived from country centroids. Used by tile_map().

Usage

world_tiles

Format

A tibble with columns iso3c, country, row, col; one row per country, with row/col unique across the grid.

Source

Derived from Natural Earth country centroids.

Details

The grid holds one row for each of the 247 countries in country_meta that has a bundled centroid; the 3 without one (BVT, GIB, UMI – see country_meta) have no tile and so cannot be drawn by tile_map().
