Descrizione dettagliata
This module defines objects describing georeferenced sparse points possibly with topology and projection information.
This module defines two classes, georef_coord, which represents a single georeferenced point on the Earth, and georef_coord_array which defines a set of points with a topological relation.
Both classes have PRIVATE members, so that they cannot be manipulated directly, but only through the proper methods.
It is also possible to dafine a dynamically extendible array of georef_coord_array objects, of type arrayof_georef_coord_array, suitable for importing/exporting data from/to a shapefile.
