The Application of the Method of Least Squares to the Closing of Multiply-Connected Loops in Cave or Geological Surveys
V.A. Schmidt and J.H. Schelleng

In addition, constraints may be applied to any part of the survey. The method is well-suited to use with computer programs for the reduction of survey data.
