In the 80, the emergence of computer programs more friendly to users and producers of information and technological developments have made international institutions, public and private, to further improve on studies of cartographic production systems supported by computer, to implement Geographical Information System (GIS). A little concurrence of forces between bodies concerned, resulted in a large amount of digital files with the need for standardization. In 2007, the National Commission of Cartography (CONCAR) approved the structure of Geospatial Data Vector (EDGV) in order to minimize the problem of lack of standardization of cartographic databases. This dissertation focuses on developing a methodology of work for the process of converting existing digital cartographic databases in the standard of Digital Topographic Map Collection, the Brazilian Institute of Geography and Statistics (IBGE) for the standard EDGV and their potential and limitations for integration and standardization of digital cartographic databases. Was made an application of the methodology using a topographic map of Saquarema, on the scale of 1:50,000, vectored in the Cartographic of Coordination of IBGE and available on the Internet. As EDGV was elaborated in accordance with modeling techniques object-oriented, it was necessary a mapping for relational database, as it is still used by most users and producers of geographic information. One of the specific objectives is to develop a schema of the database, that is, an empty database containing all classes of objects, attributes and their domains in the EDGV so it can be used in the production process mapping of IBGE. This scheme will contain all the descriptions of objects and their attributes, as well as allow the user select the domain of a particular attribute in a predefined list, preventing them from occurring error in fulfilling of the data. This metodology of working will be of great importance to the process of conversion of database existing cartographical of IBGE and, thereby, generate and make available database cartographic in the standard EDGV.
