[Loadstone] describing and storing complex points

[Hasan Karahasan]

How could we store complex objects like borders of countries, rivers, seas, 
oceans and similar?

Surely this is not interesting when walking in our home town. But I often 
use ls in exploration mode to simply explore the world.
I think of storing such a complex object as a collection of points belonging 
together. The area within this edge points then could be recognized as 
probably being the atlantic ocean or what ever. I know that for example the 
border line of a country is never an exact straight line. So this would only 
be a approximation of the discussed area. Or think of a kind of "where am I" 
question. You need at least hundreds of points to say reliably that you are 
within the area  of a metropolitan city. If you are unlucky ls will claim 
that you are not in the city but in a suburb or village near by because its 
point is closer to you than those of your down-town. Storing areas with some 
edge coordinates would solve this with an acceptable acuracy. Of course, the 
more edge point you have the better the area is described.
