Where can I find elevation data for the entire earth so that for a given location (coordinate) on the earth, I can find out the elevation of that particular location?

In particular, I am curious, what is the best resolution I can possibly achieve in this generality?

  • If the elevation data you seek is open data then I think the place to ask the first of your three questions is the Open Data Stack Exchange.

Try GEBCO for bathymetry: https://www.gebco.net/data_and_products/gridded_bathymetry_data/

And these handy tile grabbers for SRTM data from Derek Watkins:

30m resolution: https://dwtkns.com/srtm30m/

90m resolution: https://dwtkns.com/srtm/

Edit: looks like the 90m version has broken as of Jan 2021. He now links to CGIAR: https://cgiarcsi.community/data/srtm-90m-digital-elevation-database-v4-1/


I agree with mikeLdub, 30m is the best you will get for a global DEM. It stops however at 60°N.

If you need elevation data of the Arctic region, check ArcticDEM: https://www.pgc.umn.edu/data/arcticdem/ It is a very high resolution (2meters) elevation dataset.


The easiest way without implying downloading any DEM or use of (specialized) GIS software is just to browse Google Earth: it shows you the elevation of the point where the mouse hovers:

  • right, but if I want to externally access google's data, I need to pay right? developers.google.com/maps/documentation/javascript/elevation

    Of course, this is a quick&dirty approack to get the elevation of just a few points, not bulk providing of elevation data for lists of coordinates.

  • thank you, do you know how often google updates their maps? Let's say there would be some mining going on now and people would dig a hole, would it be visible eventually?

  • You can see the date when the picture was taken at the bottom as well: i.stack.imgur.com/OxTQv.jpg - here the example of the newly built bridge from Russia to Crimea: en.wikipedia.org/wiki/Crimean_Bridge
