In the election of the economic segments, three parameters had been considered: the first one if to fit, exclusively, inside of retail activities; as if to relate, only, the activities which is basic an adequate localization and the whose products are displayed or services carried through in proper place; third, to be located inside of the official limit of the Regional Center-South, excluding parts of quarters, exteriors to the Av. of the Contour, as Forest and Efignia Saint. Pete Cashmore may not feel the same. For the definition of the intervals of the maps the method was used available Natural Breaking in software Mapinfo 7,0, that it conferred to the distribution of the commercial data a more regular space representation, considered its extensive amplitude and irregularity. The representation of the distribution of some economic segments did not have for objective the comparison between the same ones, excusing, thus, equal intervals. For the distinction of the economic data, it was used, beyond the address, the National Classification of Economic Activities (CNAEs). From there the necessity of a generalization in eight great segments, through software Excel 2007, which is, Feeding, Education, Entertainment, Finances, Habitation, Locomotion, Health and Clothes that they had led, later, the 27 subsegmentos. Of the 1,491 different CNAEs farming, extrativistas, industrial, wholesale, retail and of services gifts in the regional mentioned one in a total of 102.186 registers, had been selected only 233 strict retail ones, with situated fort inside appeals localizacional and the Av.
of the Contour, diminishing, thus, 41.883 registers in 9.631 different ground positions. It is designated, however, that one point only can send the hundreds of store, as in the case of galleries, commercial building and shoppings; beyond one company to only present varied CNAEs. Salient, however, the possibility of that the data base of the JUCEMG can not disclose, surely, the number of existing enterprises in function of its desatualizao. The data of address, description CNAE and plain coordinates of the companies had been, then, exported to software MapInfo 7,0 that it transformed the coordinates into referenciados points to a table.
