Dear Ani, Package 'raster' has a function called getData(), which can download SRTM tiles. Then you can simply plot() them. Or you can use package 'elevatr'. But I'm sure there are many other alternative solutions. HTH, Ákos Bede-Fazekas Centre for Ecological Research, Hungary 2021.11.16.

[R-sig-Geo] simple topography in r

2021-11-15 Thread ani jaya
Dear r-sig-geo, I need to plot a spatial map that shows a topography/elevation. It is just to show a basic information so I do not need a high-resolution map. I already googled and most of them use ggplot. Is there a straightforward way to do this in base r? Any lead is appreciated. Thank you so
