1.3.4 MARK and CORS lists
To the right of the map are lists of project marks and included CORS. Like the map icons, holding the
cursor over a mark’s ID in the list will cause the icon to brighten, and clicking (typical left mouse button)
a mark ID in the list causes that project mark's information bubble to appear on the map identifying its
location.
1.3.4.1 Adding additional marks to the project
Below the project marks list to the right of the map is the ' Add MARKS' button (Figure 1.13). This
button acts as a link and re-direction to the OPUS Upload web page where more GNSS observations on
passive geodetic control marks may be added.
Figure 1.14 - Add CORS
1.3.4.2 Adding additional CORS to the project
Below the CORS list, at the bottom right of the map, is the ' Add CORS' button
(Figure 1.14). Clicking this button opens a new window with controls to add
additional CORS to this session (Figure 1.15).
Click the ‘ Add MARKS’ button to be
directed back to the OPUS upload page
Click the ‘ Add CORS’ button and a pop-up
CORS window will display.

Figure 1.15 - The 'Add CORS' popup window
The map appearing in the Add CORS window (Figure 1.15) is similar to the map on the primary web
page. You may zoom in and out and drag the map to other areas. Notice the CORS icons are color
coded to reflect how long they have existed as a CORS. As you zoom in to the map notice that the sites
that have been operational for shorter periods of time begin to appear. This a subtle way of encouraging
the Manager to add CORS that have existed longer, have more years of archived data, and which may
overlap the session timelines for projects with older observations.
Always use CORS that are at least three years old as this ensures that they will have computed
velocities for OP to use. CORS can be added to the entire project from the manager’s web pages after
all project data has been entered. This insures that the CORS data will overlap the timeline of all of
the mark data in the project.
When in the Add CORS window, move the cursor over the CORS icon to see the CORS ID. Clicking on the
CORS icon gives you the option (within the information bubble) to add it to a list on the left. When you
have completed adding CORS to that list, click the Add CORS button at the top of the web page to
populate your current session with those additional CORS.
Remember that if you add CORS after the session has been processed you will have to go back
and process that session again as you have now added data which should generate additional
baselines for processing.
1.3.5 Controls
Controls for common manager tasks appear on the left side of the map (Figure 1.11).
1.3.5.1 Help, Back and Refresh
Help, Back, and Refresh buttons appear at the top of the controls. The Help button is under
development and may ultimately provide the same resource as this document. The Back “moves back”
to the previous web page in the browser’s history. Its action is identical to the browser’s back control.
The Refresh button forces the project to be scanned and the manager’s web page to be reloaded. Use
this OP refresh button rather than the one for the browser.

1.3.5.2 Preferences
By carefully setting the preferences for a project, the project manager can control the automated
grouping of data files, guide data processing, and more easily identify potential problems. Some
logistical items are also controlled through the preferences. Each section within the preferences web
page will be described individually. Across the top of the window, and typical of all pop-up windows
available in OP, are controls (Figure 1.16). The two buttons on the top-left are for Help with and to
Refresh the window. The Save Changes and Close button at the top-center of this window is self-
explanatory. The (X) button on the top-right closes the window without saving.

1.3.5.2.1
Project Title, ID and Keywords
The Project Title, ID and Keyword enable a project manager to change the project title as well as the
project ID and keywords. Some find the automatically generated, random project ID and keyword
strings challenging to work with and prefer something more specific to a project or more memorable.
One may make the ID and keywords all the same or, perhaps, make the project ID and session keyword
the same, but make the manager keyword different thereby limiting access to the manager’s web page.
Changing these will cause an updated copy of the email introducing the project to be sent to the project
manager.
Project IDs are unique among all projects currently in existence. The manager's email address
is associated with the project at creation and they are associated together for the life of the project.
Manager and session keywords exist only inside the project and so might be duplicated in other
projects.
Just as when the project was created, it is strongly recommended that this information be
saved in your own project records.
Note the rules for the ID and keywords (Figure 1.17).

Manager Emails
Network adjustment results and, occasionally, other reports and notices will be sent to the project
manager's email address. The manager can have copies of these emails automatically copied (CC) to
others using the Manager Emails control. Please be courteous - only add email addresses for folks that
really want to see them.

Data and Solution Quality Thresholds
These thresholds are used to help identify project mark processing results that do not meet the
project’s preferences. Data files whose processing results exceed a threshold are not automatically
excluded. They are, however, visually identified by their icon style and color and in the
background/foreground in table entries on the web pages. Note that the initial (default) threshold
