As a node in a geodesic is surveying point or any other measurement point designated in which a plurality of measurement paths converge from different directions. Using suitable conditional equations or a mediating adjustment , the accuracy can be increased noticeably because the individual measuring sections
- correspond to a repeated calibration
- and small systematic errors act in different directions and therefore largely cancel each other out.
Junctions are used among other things
- in some national surveying methods , such as the formation of nodal networks from trusses (large-scale polygonal lines) using the Bowie method
- with exact height networks (see also precision leveling )
- with GPS leveling and with quasi-difference GPS
- for coordinate transformations at national borders.
