Homepage Terrain Maps

The contour maps behind the homepage headline show the first island chain, Guam and the Northern Mariana Islands, and the main Hawaiian Islands. The contours are drawn from elevation and bathymetry in the Terrain Tiles dataset on the Registry of Open Data on AWS, produced by the Tilezen project (formerly Mapzen). The script that builds the maps is scripts/hero-terrain.py in the site's source.
