Dear Michael, Thank you for your reply and the suggestions.
Ideally, I would like a raster from which I can extract elevation at 1° x 1° resolution. I do not have much experience with working with DEM but have work with data such as GPW. I will definitely look at the datasets. Could you kindly suggest one that I could convert to raster and extract? Hope that's not a silly question.
