Metadata: GEON Field |
The GEON (geographic name) field usually represents the country, or for some large
countries, country and state or province. However, when there are large discontinuous
regions within political boundaries, we use other geographical categories. For Example,
Easter Island (Isla de Pascua) is part of the territory of Chile, however, because it
is far from the boundaries of the mainland of Chile, we have created a separate GEON
for Easter Island. Our field lists "Geographic Region, Country or U.S. State" and
discontinuous regions are not lumped with their political ownership.
Also note that although we are aware of the many political changes going on each day,
images are cataloged at a point in time. Current political boundaries and names may not
be reflected in all the database records for some locations.
