GO meaning in Regional ?

Goiás (Brazilian Portuguese: [ɡojˈjas] (listen)) is a state of Brazil, located in the Center-West region of the country. The name Goiás (formerly, Goyaz) comes from the name of an indigenous community. The original word seems to have been guaiá, a compound of gua e iá, meaning "the same person" or "people of the same origin." It borders the Federal District and the states of (from north clockwise) Tocantins, Bahia, Minas Gerais, Mato Grosso do Sul and Mato Grosso. The state has 3.3% of the Brazilian population and is responsible for 2.7% of the Brazilian GDP.

The most populous state of its region, Goiás is characterized by a landscape of chapadões (plateaus). In the height of the drought season, from June to September, the lack of rain makes the level of the Araguaia River go down and exposes almost 2 kilometres (1.2 mi) of beaches, making it the main attraction of the State. At the Emas National Park in the municipality of Mineiros, it is possible to observe the typical fauna and flora from the region. At the Chapada dos Veadeiros the attractions are the canyons, valleys, rapids and waterfalls. Other attractions are the historical city of Goiás (or Old Goiás), 132 km (82 mi) from Goiânia, established in the beginning of 18th Century, and Caldas Novas, with its hot water wells attracting more than one million tourists per year. In Brazil's geoeconomic division, Goiás belongs to the Centro-Sul (Center-South), being the northernmost state of the southern portion of Brazil.
