To Process the Least Squares Input File for a Survey Network

The program reads the input file, network.lsi. The adjustment is calculated, and the program creates a least squares network adjustment file (network.adj) and a least squares network output file (network.lso).

  1. In Toolspace, on the Survey tab, expand the Networks collection. Right-click a named network Least Squares AnalysisProcess Input File.
  2. Use the scroll bar to review the information in the file. You can also save the output file to a new filename, or print the file to your printer.

    The least squares network output file initially displays the Survey Least Squares calculations data, based on the processed network.lsi input file.

  3. Page down to display the observation data for the network.

    The measured observations and standard deviations are the values that existed before the Least Squares adjustment. The adjusted observations and residuals are the results of the Least Squares adjustment.

  4. Page down again to display the adjusted coordinates for the network. The point identifiers, northing, easting, northing standard deviation, and easting standard deviation for each unknown point are listed.
  5. Page down to the end of the file to display the error analysis for the network. The values of the semi-major and semi-minor axes, as well as the axis azimuth of the error ellipse for each unknown point are listed.
