Every engineering surveying works require very precise and accurate measurement down to sub-millimetre. Considering this quality of measurements the highly developed survey instruments have been invented. In addition, there are numerous of measurements and adjustments methods have been proposed. The traversing is a very common method which is used to establish a high accurate control points and adjustment control networks. That is used where the control points are visible to each other, where there is enough space to setup instruments (Total Station), and where using GNSS (GPS) is available. However, in the case of having invisible control points, limited space to setup instruments (Total Station), and where using GPS is restricted or limited, it is not possible to use any traverse methods and adjustments. In order to address this problem this dissertation is proposed and examined a new method which is traversing by resection. For achieving the goal of the current dissertation ten trials have done with five main control stations. The data were collected within different observation that they are four, five, and six observations. Moreover, the tow different methods were used to calculate and analysis the data. Finally, the results achieved from the dissertation are precise and accurate, which all the results are in the confident level that they are in the range of ±σ and ± 2σ.
