Comparative analysis of the accuracy and reliability parameters for models of classical leveling traverse and that of modular one is the main goal of the paper. Accuracy studies were done on the basis of the preliminary accuracy analysis. The height mean error and the global reliability parameter were assumed as the comparative criteria. Redundancy of observation set was considered as well. A suggestion of numerical working out the height modular traverse is presented. The method shown here can be useful to inventory and setting out measurements for linear objects (e.g. transport routes, water races).
