Hi Janosch, Sorry for the delay in answering... The philosophy of the procedure is the same: you need to have the geographic lat/lon coordinates of the lower-left and upper-right corners of your map. You can plot your original map with -Jx and without boundary annotations, and then overlay the geographic information of the axis using psbasemap, -Ju (using the same scale), -R (defined with the lat/long of the two corners) and -B with the desired annotation interval.

This script seems to be for adding UTM data to a stereographic projection. I want to add WGS lat/lon instead of UTM.

I currently have a map of a section of Antarctica. The data I am plotting is in the Antarctic stereographic projection.
