Abstract
The advances of the microelectronics applied to the instruments used in Topography and Geodesy have led to the development of precise, light and easy handling equipments, as the Total Stations, which have enormously facilitated the field work. With such characteristics, an issue raises: the achievement of the precise difference in elevation when using the method of trigonometric leveling with total station. A research was carried out in order to find out the accuracy in the determination of elevation difference by trigonometric leveling using total stations classified by the Associacao Brasileira de Normas Tecnicas (ABNT) as of low, medium and high precision - in comparison with the elevation difference obtained by the method of the differential leveling established in accordance with the Especificacoes e Normas Gerais para Levantamentos Geodesicos do Instituto Brasileiro de Geografia e Estatistica (IBGE). The results present the expected accuracy and depend on the precision of the total station.
