South America & Western Europe SRTM 30 m in Esri World Elevation Services

Esri World Elevation Layers  are enhanced with more detailed void-free 1 arc-second (~ 30 meters) SRTM data (Version 3.0) from NASA for South America, Western Europe, Central America and Caribbean Islands. With this update, there is now 3 times more detail in these areas.

AconcaguaArgentina_SRTM90_30Aconcagua, Argentina—the highest peak in South America at 6,962 m (22,841 ft) above sea level (SRTM 90m vs SRTM 30m) 

OjosdelSalado_SRTM90_30_55kOjos del Salado—the highest active volcano in the world at 6,893 m (22,615 ft) on the Argentina–Chile border (SRTM 90m vs SRTM 30m) 

ChimborazoEcuador_SRTM90_30Chimborazo, Ecuador—an inactive stratovolcano and highest peak in Ecuador at 6,268 m (20,564 ft) above sea level (SRTM 90m vs SRTM 30m) 

MontBlanc_SRTM90_30_72kMont Blanc—the highest peak in the Alps, Europe, at 4,810 m (15,781 ft) above sea level (SRTM 90m vs SRTM 30m) 

Our dynamic world elevation image services (Terrain and TopoBathy) are not just for visualization (such as multi-directional hillshadetinted hillshade) but provide access to raw elevation values and derivatives (such as slopeaspect) for analysis. Access to these global layers is free and does not consume any credits; all you need is an ArcGIS Organizational account. It’s that easy!

Previously released Africa is also refreshed with void-free SRTM 30m (Version 3.0) from NASA in this update. Stay tuned for updates on Asia and Australia.
