SUMMARY:

Urban expansion is a very important phenomenon that occurs more significantly from
the 1950s, when there was a large growth of cities due to migration caused by rural exodus and
technological advances, especially in industries, which reflected in a greaterconcentration of
people living in an increasingly smaller space in cities. In Maceió, this dynamic occurs similarly
to other capitals in the northeast and Brazil, that is, accelerated and often disordered. However,
the capital of Alagoas has two situations that directly harm the urban space and its proper
planning: the subsidence process of the neighborhoods of Pinheiro, Bebedouro, Bom Parto,
Farol, and Mutange, as a result of salt extraction activities, causing the extinction of the last
listed neighborhood; and the delay of 8 (eight) years in the revision of the Municipal Master
Plan, directly harming the management of the municipal territory. The proper use of the
municipalterritorydependsonknowledgeofbothitsphysicalcharacteristicsand
socioeconomic conditions, therefore, this work contributes to solving this demand together with
others developed in the municipality, and that at an opportune moment, such information will
be used by the responsible agencies for the management of the municipal territory, as well as
in the elaboration of normative instruments that assist in its proper ordering. Tools and
techniques related to Remote Sensing and Geoprocessing were used for the elaboration of this
study, using GIS, where information plans were used/generated/improved at a scale of 1:25.000,
with the aim of identifying potential and legal areas for urban expansion. For this, a multicriteria
analysis was used through the AHP method (Analytic Hierarchy Process) and map algebra
performed with the application of weighted average. As researchresults, it was verified that in
Maceió there is a total of 19.955,02 hectares with high or very high potential, which represents
19,75% of the total area ofthe municipality, while the low and very low potential classes
represent 9,10%, which implies that the capital still has areas that are receptive to urban
expansion and are suitable for use at an opportune moment, since there are still empty areas
(urban voids) in the urban zone of Maceió that can be occupied, with the proper use of the land,
so thatthe urban sprawl is not carried out without proper planning, making this phenomenon
increasingly burdensome for the state, considering the need for infrastructure and services in
areas where they do not exist.
