[R-sig-Geo] Elevation data

[Michael Sumner]

Passed through? Maybe you want ?raster::extract

There are a few versions of global elevation on CRAN, necessarily at low
resolution but no overall summary afaik (someone should do this :).

This is one: https://cloud.r-project.org/web/packages/GEOmap/index.html

If you have the stomach for development versions of packages see elevatr:
https://github.com/jhollist/elevatr

I tend to have the high-resolution files at hand because we use them
constantly, the main ones are Gebco14/Gebco08 and Etopo1/Etopo2 (from
Smith-Sandwell).

There's a reasonable overview here, you probably should find a specific
data set that is at the resolution you are after already, and you can cite
its derivation for your work:

Cheers, Mike.
