Resumo

Goiânia, capital of Goiás State, is a relatively young city, but it has experienced an intense process of urban growth. Although it was planned, nowadays its space reflects decades of failure in land management. With the aim of highlighting the city‟s expansion and land use management, we analyzed legal documents governing land use in Goiânia, as well as the academic studies that investigated this phenomenon since the city‟s foundation in the 1930s. For the period between the 1980s and 2010, we elaborated cartographic material based on satellite images Landsat 5. A simplified legend was defined with only four classes of land use (urban, agricultural, vegetation and water bodies) to enable a comparative evaluation between the various periods and thus to highlight the changes that have occurred. It was found that master plans had a significant role in defining the directions of urban expansion of Goiânia. However, these instruments have been neglected in many periods, resulting in uncontrolled growth phases, as evidenced by the presence of urban voids and unplanned vertical densification.
