Network Adjustment

Axis3D NET - Network Adjustment

Network adjustment for demanding engineering surveys

network adjustment Precise results: Tested calculation routines for reliable results.

Complex networks: Individual computation of weighting, scale factors, and refraction coefficients allow using heterogeneous data.

Easy error detection: Comprehensive routines find errors, even in complex networks.

Efficient workflows: Intuitive user interface guides the user through the project and speeds work up considerably.

Measurement Data and Network Datum


Network Graphics

Network Datum Checking and cleanup of measurement data is simplified by proven routines, eliminating gross errors and mixed targets before the adjustment. Efforts for the definition of network datum are minimized due to automatic calculation of approximate coordinates.
Adjustment Robust adjustment routines, including the calculation of additional parameters such as scale factors, refraction coefficients, or gyroscope constants, ensure highest accuracy results. The individual weighting of measurement data includes distance-related measurement and reference point accuracies, as well as centering errors. These sophisticated features, combined with an intuitive user interface, enable a professional analysis of measurement data.
Network Graphics The graphic presentation of sightings and points, including error ellipses and height errors, gives a comprehensive overview of the network. As point IDs are shifted automatically to blank areas, the graphics stay clear, ensuring a good overview to judge the network design and quality at a glance. Export to scale as DXF or PDF files.
