The history of census in Brazil shows that the worry with the territorial component in statistical surveys appeared in the 1940 Census. For the first time the Brazilian Institute for Geography and Statistics (IBGE) tried to describe aspects of the geographic reality, of interest for the assembling operation in cartographic basis a complex task due to the great extension of the Brazilian territory and mainly in relation to the quality of the cartographic material available at that time. Nowadays in our country the demands for more detailed and geographically positioned data grow governors and majors, planning institutes at municipal and state levels, owners of more autonomy and new responsibilities after the 1988 Constitution depend today as never before on the census to define their public policies based on up-dated data on the population under their jurisdictions.Nevertheless the demands for date linked to the position come also from other areas which range from the non-governmental and private sector of the Federal Government increasing the importance of census and by consequence the results of the researches. To respond to the great demand, the IBGE continuously implement the so-called Territorial Base, which is an integrated data system of geographical nature and alfa-numerical and it is the main requisite for the warrant of the adequate cover of the census operations. Due to this new scenery, IBGE started the elaboration of maps of the territorial base through digital means during the preparation actions for the 2000 Census, facing difficulties concerning the integration of urban and rural areas and the low quality of mapping data in cadastral scale, available in less developed areas once the institution does not produce in a cadastral scale.The methodology proposed aims at improving the quality of Urban Sectors Maps MSU, using the Google Earth images, from the software Micro Station 95, peripheric and applicative of conversion available at IBGE, with the establishment of a new routine of work for the production and replacement of the maps of the urban sectors, in order to guarantee a greater territorial representativeness of statistical data for dissemination.
