VARGAS, R. M. A. (2001). Analysis of Global Positioning System (GPS) applications in urban roads surveying. São Carlos, 2001. 139 p. Dissertação (Mestrado)Escola de Engenharia de São Carlos, Universidade de São Paulo. The surveying for development of urban roads are usually accomplished by using instruments and processes of classic Topography. The presence of obstacles (houses, buildings) along the course ít reduces the productívity of the work besídes contríbutíng for the ímprecísion of the results. This work analyzes the methodology of use of receivers of the GPS (Global Positioning System) for georeferring, ímplant of support bases and complementation to the surveying with Total Station. In the development of the project of a road, it is expected that centimetric deviations in the determination of the points coordinates of the reference bases cause small effects in the final results. Trying to verify the contríbution of these deviations, severa! surveys were accomplíshed with the Total Statíon and GPS along the axís of a road projected in the city of São Carlos. In the end of the work severa! aspects are analyzed about the execution of these surveys, concluding on the advantages and disadvantages of each method and of the integration GPS and Total Station.
