I am looking for gridded population data and elevation data on the same grid. I saw on your website that you have compiled a population dataset - is there an elevation dataset that can go with this, and can you help me obtain it?

There are two global elevation data sets that I know of, both are at 30 arc-seconds (0.5 arc-minutes) in resolution (GPW is 2.5 arc-minutes). You can get them on the web at:



To get these to match to the GPW grid you just need to resample them by a factor of 5, I’d recommend either cubic convolution or bilinear as the interpolation method.

There is also detailed elevation data for different parts of the world from NASA’s SRTM but it is too much detail in comparison to our GPW data.
