Properties

The properties in the table below can be used in these parts of fiboa documents:

• Collection
• Feature Properties

Property Name	Type	Description
admin:country_code	string	REQUIRED. ISO 3166-1 alpha-2 country code (aka admin0). Two-letter country code for the country that contains the field.
admin:subdivision_code	string	ISO 3166-2 codes for identifying the principal subdivisions (e.g., provinces or states) of a country (aka admin1) that contains the field. The feature only contains the second part of the ISO 3166-2 code to reduce redundancy.

The codes can be found at:

• Search for country codes at https://www.iso.org/obp/ui/#search via the Alpha-2 code column.
• The subdivision codes can then be accessed at https://www.iso.org/obp/ui/#iso:pub:PUB500001:en

Please note that for some countries subdivision codes are not available.

Examples

1. California, USA: admin:country_code = US and admin:subdivision_code = CA
2. Bavaria, Germany: admin:country_code = DE and admin:subdivision_code = BY
