You don't really correct distortion - you change projection types
and/or the projection point.

What are your options for exporting the data from the program?
Given, for instance, lat/lon points such that connecting them
in the order given yields the desired coastline, I have programs
I've written to create a variety of projection types and turn them
into Postscript documents - although I can do other image formats
as well.
