The orthometric height determination for points located in areas of difficult access, for example, in mountainous regions, is one of Geodesy challenges, because the transposition of great cliffs and valleys is necessary, often without access roads, which makes unfeasible the use the geometric leveling. Modern height determination techniques from trigonometric leveling are being studied, seeking equivalent accuracy to geometric leveling and to make easy this task for these regions. In this paper is accomplished the height determination to the peak Camapuã, on Serra do Mar in the Paraná State. The methodology is based on the Leap-Frog trigonometric leveling, involving single sight lengths of about 6000m with height differences of almost 1000m. The results and an evaluation of method are presented.
