Global islands

June 26, 2020

A new map of global islands at a high spatial resolution (30 m) has been produced from a semi-automated interpretation of 2014 satellite imagery. The data are available in the public domain. The islands were classified by size into continental mainlands (5), big islands > 1 km2 (21,818), and small islands ≤ 1 km2 (318,868). The new high-resolution islands data are intended to support coastal ecosystem mapping efforts and assessments of threatened island biodiversity, among other applications. This chapter summarizes the global island mapping approach and results.
