I am trying to find out the highest and lowest elevation for these types of geographical areas:
- continent (lots of ways to get info)
- country (lots of ways to get info)
- state (for the US states no problem, but what about other countries' federal states?)
Perhaps there a web service that gives such kind of information. Especially state and city I have problems finding elevation info on.
If not, what is my alternatives? Maybe I need to do it "manually"? I found via Google SRTM 90m Digital Elevation Data, is this a good way to get the elevation data I need? But then how could I use this to find it for a state or city?
