Carlson SurvNET: True Network Least Squares
This program, unlike other Network Least Squares program, automatically means all horizontal and vertical angles including slope distances. No need to manually mean and input all multiple direct or reverse or closed horizon pairs of angles and distances; SurvNET does this automatically.
SurvNET also automatically weights redundant angle and distances, it applies and reports these new standard errors after adjusting. SurvNET Network Least Squares reports include mean angle and distance splits prior to adjustment, error ellipse reports, and positional tolerance inversing for Alta Survey compliance.
