Heard Island Map
Heard Island is an island in Australia in the Indian Ocean, covering about 368 km² (142 sq mi). This map shows the island on shaded relief, with its relief, rivers and towns.
How to read this map
The highest point is Mawson Peak, 2,745 m (9,006 ft) above sea level.
The map is centred on Heard Island.
Greens show lower elevations; tan and brown show higher land, with pale tones toward the highest terrain. Shadows emphasize the slopes, and vertical relief is exaggerated so landforms are easier to read. Dashed lines show country borders.
The relief uses Terrain Tiles (SRTM, GMTED2010 and ETOPO1 elevation data). Rivers, lakes, borders come from Natural Earth, and the figures on this page from Wikidata. These are small-scale educational maps, not navigation charts.
