Maximal precision increment method utilization for underground geodetic height network optimization

Popis výsledku v původním jazyce

Nowadays, optimization of the measurements is an important theme of the geodesy and especially engineering surveying. The optimization can be categorized into orders, from the zero to the third order. The zero order design is the coordinate system selection; the first order is the configuration optimization; the second order is the optimization of the number of the repetitions; the third order is the improvement of the existing network by adding point and/or observations. In the engineering surveying, the second order design needs to be addressed. Thus, there are known possible locations of network points, the desired accuracy, possible measurements within the existing situation, and it is necessary to choose such measurements and their numbers of repetition so that their number was minimal (resp. used energy on their implementation) and yet the required accuracy was met. There were many attempts to meet this objective, but usually by the deployment of general mathematical optimization methods that do not respect the character of geodetic measurements and rational optimization results demands. There was designed a new method which, in our opinion, meets these requirements and is based on a gradual selection of the most beneficial measurement to meet the accuracy requirements. The method was successfully tested on the leveling network optimization. The method is very suitable for use in mining and tunnel surveying, wherein it allows economic planning of the accuracy of the measurement, which is important both in economic terms and in terms of safety. The economic aspect is important not only in terms of money spent on the measurement, but also in terms of minimizing downtime of a mine operation and equipment.
