Least Squares - Step 3 - Report Page

Overview : Step 1- Analyze -----> Step 2 - Solve -----> Step 3 - Report -----> Step 4 - Update

---------------------------

The Least Squares report dialog allows you to select the information you want to see about the solution. TPC creates a separate Least Squares Report view and places the requested information in it. You can edit or select any of the information in this report, print it, copy and paste it to another application or append it to the current Survey Report.

If you need to update your Least Squares adjustment, proceed to Step 4- Update.

Settings

Lists all the units and assumptions used in the analysis, including the A Priori values.

Unadjusted Data

Lists the unadjusted coordinates and observations in the order 1) fixed stations, 2) free stations, 3) observed angles, 4) observed distances, etc.

Residual / Corrected

Lists the corrected (adjusted) observations and their residuals. This information is important if you are looking for potential problems or blunders in your network.

Adjusted Coordinates

Lists the adjusted coordinates and their standard deviations. This is usually the first place you go in the report to see how good the analysis was.

Statistics

Lists the statistical information about the solution.

Ellipse Values

Lists each computed station along with it's error ellipse.

Blunders

If blunder detection was turned on when the network was solved, TPC reports any found blunders here.

Positional Tolerance

See Positional Tolerance.

Relative Positional Accuracy

See Relative Positional Accuracy.

Report

Add the points and observations in this analysis to the current Report View. You can also choose to include these in the report when you solve the network.
