SAŽETAK / ABSTRACT:

In today’s globalised society, where more and more of the goods and services are being routed automatically, there is a growing necessity to use a global location coding system.  The longitude and the latitude are global indicators of dimensionless points on the sphere, but, in reality, most locations of practical interest could be considered as areas covering a definite surface.  It may be argued that a point within that surface may be used as a location indicator, but this indicator is not unique.  The other issue with the geographical coordinates is that to the coordinate of any particular point of interest a tolerance interval need be included.  Thus, location indication through area codes is natural and more useful.  In this work, the authors propose a global system for indicating geographic areas through limited sequences of decimal digits.  Each such sequence of a certain length indicate in a unique manner a definite geographic area. Sequences of increasing lengths indicate the smaller areas, i.e. with a narrower tolerance.  This method for location coding is achieved by dividing recursively the surface of the Earth in sections, and then recursively into smaller and smaller subsections, with each new division encoded by a single digit.  E.g. a twelve digit sequence indicates an area of about 50 m in diameter.  Using such global coding system for geographic locations may substantially simplify the delivery of goods and services, direct and focus a remedial effort in emergencies, or be used advantageously for planning and improvement of city management.
