I'm getting interested in making some maps for some of my personal research in Central Asia. I started using QGIS today, and I feel like I have a pretty good handle on some of the basics, but I want to go ahead and work with a real dataset in my area of interest.
I've been looking around for datasets involving central asia, china, mongolia. However, I'm not entirely sure what I need. I see maps like this one on wikipedia:
and I want to make something similar. Ideally, I would like to make maps of a small region between several towns (perhaps with a map of 50km x 50 km). What resolution of topographical/elevation data would I need for that size of map?
Thanks for your time, if I am asking something too vague or asking the wrong sort of question I would appreciate any guidance.
