STEP 10 (OP5): Running an Adjustment and Viewing Results

1. First complete all session processing of the static data in the project as per step 9 above and as explained in the User Guide.

2. Next, run the “preliminary” adjustment as instructed in the OPUS-Projects User Guide. Include all sessions in the adjustment.

3. You will receive an email with the preliminary adjustment results. This adjustment will only include the baselines derived from the static survey. Next, refresh the project in OPUS-Projects 5 and click on the “Set up Adjustment” button again.

4. A new window will open for running a network adjustment. The next step will be to run the “Horizontal free” adjustment. Highlight the names of the GVX file(s) in the right column of Available Solutions as well as the name of the final network for the preliminary adjustment (in the example below, this is “network-final”).

5. Next, click on the arrow pointing left to move these file(s) to the left column labeled “Included Solutions”. This instructs OPUS-Projects to use both the vectors in the GVX file(s) as well as the vectors from static session processing. Ensure that you select a mark to constrain so as to apply minimal constraints for the network (the horizontal free adjustment is a minimally constrained adjustment; we recommend constraining the hub station in 3-D).

6. At the top of the adjustment window, click on the blue button labeled “Perform Adjustment”. A new window will appear, summarizing the setup of the adjustment. Hit the close button to close the window.

7. Wait a few minutes, then hit the refresh button. If nothing changes, try waiting a little bit longer, then hit the refresh button again. The map should change so that it shows green lines (indicating that the baselines in the GVX file(s) have been adjusted). See below for an example of expected results. You should also receive an email with the adjustment results attached.

8. You may view the results of the adjustment. One way to do this is to click on one of the points (diamonds) on the map. A popup window will appear for the point. Click on the point’s 4-character name in the upper left corner of this popup window.

9. By clicking on a point’s name, a new webpage will appear, known as the “mark webpage”. This page presents lots of information about a selected mark in the project, including all data collected on the mark and its coordinates. Scroll down to view the final adjusted coordinates in NAD 83(2011)(2010.0000) for the selected mark. Scroll down to the bottom of the page, and you can see scatter plots. Each plot should have a green point with error bars, indicating the adjusted coordinates of the mark.

10. Another method for viewing adjustment results is to return to the manager’s webpage. This can be done by clicking on the button labeled “Manager’s page” on the left-side menu. Then, click on the button labeled “Show File”. A new window will appear, allowing the user to choose a file for viewing. Change the dropdown boxes to present the “Network Solution” for the “network-GVX-only-horizontal-free” adjustment and “Summary”. Then click the Show File button next to the last dropdown box. A text report will appear, presenting a summary of the adjustment results. Other files can also be viewed using the dropdown boxes in the “Show File” window.

11. Complete the other adjustments in a similar manner. The User Guide is up-to-date for guiding you through the horizontal constrained, vertical free, and vertical constrained adjustments.
