The file is part of my old cartography package. There are some tools there to project these and other data from cylindrical equidistant to a sphere and 2d projections through warping (http://www.research.ibm.com/dx/proceedings/cart/index.htm). The networks, data and macros referenced by the tutorial there is at http://www.research.ibm.com/dx/bonuspak/applications/cartography/
You can use Slab twice (once in each dimension) to subset the data from global coverage.

Making an image you see the the topography of the whole world in a plan presentation (that means not as a sphere) beginning at 0 deg longitude and ending at 360 deg longitude. Does someone of you know how I can make a plot, that doesn't start at 0 deg but at an arbitrary value, maybe 100 deg longitude? How can I choose an arbitrary area of the world in order to zoom on it? Is it possible to convert this plan presentation to a sphere?
