One location on the globe, in any coordinate system. geo::point tries to hide the maths and the coordinate system in which the point is represented.

one of the most confusing things when handling geometrical data, is that sometimes latlong, sometimes xy are used: horizontal and vertical organization reversed. this package tries to hide this from your program by providing abstract accessors latlong(), longlat(), xy(), and yx().

this package provides the following modules:
* geo::line - a sequence of connected points
* geo::point - a point on the globe
* geo::proj - simplified wrapper for geo::proj4
* geo::shape - base class for 2-dimensional points on the earth
surface
* geo::space - a collection of various items
* geo::surface - a surface description
