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.

About the author

Rajinder has more than 16 years of experience in GIS and Remote Sensing. He came to Esri about 12 years ago and has worked with various teams in different capacities. In his current role, he leads the community elevation program at Esri and has wide experience in cartographic visualization, image processing, databases and geo-processing. By virtue of his strong research interest in terrain visualization, Rajinder has developed a multi-directional hillshade (esriurl.com/NextGenHillshade) algorithm to improve terrain visualization in Esri basemaps, which is also available as part of world elevation layers. He has also developed a fusion technique (esriurl.com/NAGIfusion) which maintains details and colors when integrating colored rasters with hillshades. Rajinder holds a Master of Science degree in Geoinformatics from the International Institute for Geo-Information Science and Earth Observation (ITC), The Netherlands, and a Bachelor of Science degree in Urban & Regional Planning from GND University, Amritsar, India.
