| Abstract | SUMMARY The cadastral database contains all important information about the cadastral unit or land parcel, both physical data and socioeconomic data. The Brazilian cities, in their great majority, don't get to maintain a building cadastre with trustworthy data, mainly in areas of great urban expansion. This fact causes a deficient outturn and in consequence a smaller volume of investments by municipal government in benefit to the local population. Although in Brazil there are mechanisms that allow to the municipal districts to obtain the federal government's resources to implant cadastral updating politics, the results aren’t efficient. In many cases, with the obtained resources, practically carry out a new cadastral surveying of the municipal district, that generate high costs and it contributes by updating in short periods of time not be accomplished. That also happens because a lot of cadastral updating methodologies don't make use of new technologies and approaches that can get a fast and effective result with low cost. It also contributes to that situation the fact that there is a lack of qualified professionals in the Brazilian municipal administrations to plan the actions of the cadastral politics. This work presents a new updating technique of building physical data, using the existent concepts in manipulation of images and database. With the use of change detection procedures in images of different times from two test areas of the city of Presidente Prudente, Sao Paulo estate, were evaluated the changes in the value of built area of each property in a semiautomatic way, because the value of built area is the factor of larger weight in the calculation of the urban tributes in Brazil. With the aid of the cadastral database it was possible to verify if the found change was relevant so that a cadastral updating of the property was executed. If the change was relevant, the cadastral inscription of property in subject was separated, so that together with other properties of the same area, they were ready to have their data updated. Experimental results from real data allowed observing that was obtained a significant reduction of the time spent in the cadastral updating at the used test areas, about 60 – 80 percent, consequently with reducing costs too. |
