This study investigates the process of urban growth in Altamira (Pará State) in the period 2000 – 2010 and the effectiveness of planning tools to regulate the growth of the city. The city of Altamira, located in SE Pará State, underwent major territorial changes starting in the 1970s, with the acceleration of the agricultural frontier expansion in the Brazilian Amazon. New forms of occupation were juxtaposed to urban structures inherited from previous periods concomitantly with the city expansion. During the 1970s, its urban population grew at a rate of 16% per year. In subsequent decades, growth rates decreased, reaching an average of 3% per year between 2000 and 2010. In recent years, the construction of the Belo Monte hydroelectric power plant can be associated with new transformations in the city.
Data integration - satellite imagery, orthophotos, field data and census data - is performed for the identification and analysis of the city structure and its expansion between 2000 and 2010. The main elements of urban structure are the regional roads and access corridors with industrial plants, high-income neighborhoods and natural attraction (Xingu River). Secondary elements of the urban structure are the central and sub-central district for commerce and services, and the majority of residential neighborhoods.
