Viewing Inverse, Mapcheck, and Output Data
In the final steps of this tutorial, you will review inverse data for the road, mapcheck data for the property lines, and the overall output data for the project.
First, check the road inverse data.
From the Analysis/Figures menu, choose Figure Inquiry
Inverse.Select figure: (pick a point on the road)
The road inverse data is displayed in the AutoCAD text window.
When you have finished reviewing the road inverse data, switch back to the AutoCAD graphics screen.
Press any key: (press ENTER)
Select figure: (press ENTER)Next, run a mapcheck on the property line.
From the Analysis/Figures menu, choose Figure Inquiry
Mapcheck.Select figure: (pick a point on the property line)
The property line mapcheck data is displayed in the AutoCAD text window.
When you have finished reviewing the property line mapcheck data, switch back to the AutoCAD graphics screen.
Press any key: (press ENTER)
Select figure: (press ENTER)Finally, view the output file in your ASCII text editor.
From the Data Collection/Input menu, choose Output File
View File.The output file contains all the information entered and displayed in the Survey program since you started this project. You can toggle this file on and off at any time using the On/Off command. You can also print it as a report for inverses, mapchecks, point coordinates, or any information displayed by Survey commands.
Scroll down to the mapcheck information at the bottom of the file. You can also view or edit this file in any ASCII text editor.
When you have finished reviewing the output file information, select File
Exit to exit your ASCII text editor.From the File menu, choose Save to save the drawing.
Adjusting a Traverse LoopThe first method of reducing survey data is the conventional Compass Rule method. Begin by defining a traverse loop.
From the Analysis/Figures menu, choose Traverse Loops
Type SURVEY TUTOR as the Traverse name.
Accept the default loop number, initial backsight point number, occupied points, and final foresight point number.
Click OK to save the traverse loop and return to the drawing.
Check the initial adjustment and make sure there are no field or typographical errors in the traverse data.
From the Analysis/Figures menu, choose Traverse Loops
Enter loop number <1>: (press ENTER)
The Traverse Loop Adjustment Settings dialog box is displayed.
Select Equal Distribution as the Vertical Adjustment.
Select Compass Rule as the Horizontal Adjustment.
Click OK to continue.
The horizontal traverse analysis data file, an1.trv, is displayed in your ASCII text editor.
Note If the traverse does not meet the closure limits set in the User Specified Limits section of the Traverse Loop Adjustment dialog box, then a warning dialog box will be displayed. If this occurs, click OK to continue.
Any angle or distance errors are reported at the end of the data along with their associated point numbers.
When you have finished reviewing the horizontal traverse analysis data, select File
Next, the horizontal traverse adjustment data file, 1.lso, is displayed in your ASCII text editor.
When you have finished reviewing the horizontal traverse adjustment data, select File
Next, the vertical traverse adjustment data file, fv1.trv, is displayed in your ASCII text editor.
When you have finished reviewing the vertical traverse adjustment data, select File
Next, the Adjustment Results dialog box is displayed.
Click OK to return to the drawing.
At this point, you can adjust the traverse and sideshots by using the Adjust Loop command, or by using the least squares adjustment method which is covered in the next section.
