With the objective geographically to locate the situated archaeological sites in the city of the Brejo da Madre de Deus, Pernambuco state, the Geographic Information Systems (SIG) was applied, in an eminently archaeological work.
Based upon SC. 24-X-B-III Belo Jardim and SB. 24-Z-D-Vi Santa Cruz do Capibaribe, the city of the Brejo da Madre de Deus encloses an area of approximately 845 Km2 of surface, being fit in the microregion of the Valley of Ipojuca, intermediate area between the humid bush and semi-arid hinterland.
Having knowlwdge of expressive amount of archaeological sites in this city, a bank of coordinate was confectioned of these sites, in order to get greater accuracy for the position and/or plotation.The tracking of the topographical points (sites) was assisted with the use of the Global Positioning System (GPS).
In each locative point, ambient informations on the proximity of the sites duly had been catalogued in specific fiches for a confrontation with the data observed after the plotation of sites in digitalized maps.
The analysis of this pilot area (Brejo da Madre de Deus), still that in small scale, it was complemented with images of satellite, digital letters and air photographs, searching to visualize the points located under some perspectives (archaeology, geology and vegetation).
Systemize this data set under an archaeological perspective, it was possible to raise information how much to the exploitation of the spaces used for prehistoric groups, identifying the areas of bigger anthropic activity in function of the available features in the identified ecological environments; visualized, in set, through digitalized maps.
