This dataset is sourced from the International Organization for Standardization (ISO) and Natural Earth Data. This list states the ISO 3166-1-alpha-2 code elements for 250 countries (two-letter abbreviations in English) in alphabetical order.
This list is updated whenever a change to the official code list in ISO 3166-1 is effected by the ISO 3166/MA (Maintenance Agency).
ISO 3166 is the International Standard for country codes and codes for their subdivisions. The purpose of ISO 3166 is to define internationally recognized codes of letters and/or numbers that can be used to refer to different countries and subdivisions. However, it does not define the names of countries (Source: Terminology Bulletin Country Names and the Country and Region Codes for Statistical Use maintained by the United Nations Statistics Divisions).
This dataset also consists of the geographical information for different countries which involves the list of neighboring countries, centroid latitude, centroid longitude and Universal Transverse Mercator (UTM) Grid points. Each country is under one or more cells of the UTM-grid, that is the main standard to describe country territory in a local-planar projection.
