Notes from the Maintainers

Source: southamerica (Lines 970 to 980)

Other Atlantic islands have no permanent settlement.
These include Trindade and Martim Vaz (administratively part of ES),
Rocas Atoll (RN), and the St Peter and St Paul Archipelago (PE).
Fernando de Noronha was a separate territory from 1942-09-02 to 1989-01-01;
it also included the Penedos.

Amapá (AP), east Pará (PA)
East Pará includes Belém, Marabá, Serra Norte, and São Félix do Xingu.
The division between east and west Pará is the river Xingu.
In the north a very small part from the river Javary (now Jari I guess,
the border with Amapá) to the Amazon, then to the Xingu.
