How to read this map
The Grand Erg Occidental is about 75,000 km² (29,000 sq mi) in area. Its typical elevation is about 500 m (1,640 ft).
The dashed outline marks the Grand Erg Occidental as mapped by Natural Earth. Towns and cities on the map include Errachidia, Ouargla, Béchar, Ghardaia and Aïn Séfra.
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 and the outline of the Grand Erg Occidental come from Natural Earth, and the figures on this page from Wikidata. Natural Earth draws features at a small scale, so the outline is a guide to where the Grand Erg Occidental is, not a surveyed boundary.
