Subject: [ggl] map to cartesian

Hi Barend, all,
regarding transformations from one coordinate system to another, I can see
that the example below mentions Map projectons.
http://geometrylibrary.geodan.nl/06__transformation__example_8cpp-example.html
Is there a way to transform GIS positions into simple cartesian x,y
positions.
If you were to draw a country loaded from a kml file or shapefile, how would
you proceed?
I guess you need to transform the lat/long vertex positions into x,y and
apply the polygon geometry for each set of x,y pairs.
How ggl can help in this context?
I guess it's also possible to use the simplification functions provided with
ggl in this context, right?
Thanks,
Fausto
