I'd highly recommend this approach - no programming needed, only
editing a simple text file, then running the command.
A final attempt at making the generation of maps to my web-page
easier, I have an alternative approach to suggest:
1. Go looking for .osm (XML) map files
2. Convert XML to text files and run the output text-file through
GNUplot and output as PNG
To test, I threw in a snippet of a converted .gpx file into the latest
GNUplot:
33.900649900 35.483151600
33.900643300 35.483158300
33.900644900 35.483195000
...
... (lan/lot) and this is what came out:

This has been done before, but I think it is safe to say that it is
not a widely used approach:

http://wiki.openstreetmap.org/index.php/Print_OpenStreetMap_with_Gnuplot
This reduces this part of the project to a relatively basic character
conversion job done with some bare-bones unix conversion utilities.
And - given that plenty of OSM-data is out there - lets me stay away
from the binary shapefile-format.
As my thesis in general is going to discuss open formats and longevity
of data and software, this looks like more the kind of solution that
in sync with the rest of my theoretical discussion.
Has anyone got any strong opinions or warnings about this approach?
