This repository contains GeoJSON files for four (4) versions of Null Island:
- The original Null Island used in the GeoIQ Acetate basemap in 2010 (source) and the Stamen Toner and Terrain basemaps in 2011 (source).
- A 1-meter-square Null Island included in Natural Earth v1.3 in 2011 (source)
- A larger Null Island polygon created by Nicholas Furness in 2014 (source)
- A 1-kilometer-square Null Island included in Natural Earth since v4.1 in 2018 (source)
And also, a viewer to compare all four.
