Remote Sensing Applied to the Delimitation of Historical Centers

Purpose: This paper aims to propose the delimitation of historic center Feira de Santana from identification initial urban fabric, since some old hovels were demolished and others had their facades altered.
 
 Theoretical framework: with a theoretical framework I tried approximate geoprocessing practices studies centers. Since no work was found that studied centers these remote sensing techniques.
 Method/design/approach: To identify center, georeferencing map used as function SPOT 05 image, then object-oriented (OBIA) classification applied, spectral responses roofs differ newer buildings.
 Results conclusion: The statistical performance classifier excellent, in addition high spatial correlation historical map, based on this, it possible polygonal Feirense municipality, not only visual interpretation, but also parameters.
 Research implications: does seek exhaust discussions regarding this suggest first polygon for municipality Santana.
 Originality/value: It is intended new technique delimiting centers, emphasizing method valid all municipalities, those have sociocultural characteristics similar Santana.
