DETAILED HORIZONTAL GEODETIC CONTROL NETWORKS TAKING INTO ACCOUNT THE ACCURACY OF THE REFERENCE POINTS

Edward Preweda

Abstract

Regardless of the nature and type of geodetic control networks, their task is to create a base for determining the position of various objects on the surface of the Earth. In the whole globe there is a need to conduct detailed geodetic measurements and to develop their results in the binding spatial reference system. In Poland, three classes of accuracy of terrain details are designated. Of all the field details, the highest accuracy of position determination is required for border points. This results from the need to guarantee, with adequate accuracy, ownership rights within certain limits and to protect property interests of real estate parties. In practice, border points, in the case of classical measurement methods, are determined on the basis of detailed or measurement networks, which are aligned with the assumption that the connection points are flawless. At the same time, the current legal provisions relate to the accuracy of determining the location of the boundary point to the geodetic control network of the 1st class. Therefore, it is necessary to use a different approach to the problem of leveling horizontal geodetic control networks and determining the accuracy of terrain details, also taking into account the accuracy of the points of establishment. The paper presents the results of research and conclusions resulting from this approach to compaction of detailed networks.
