The Project Manager's Web Page
At the bottom of the Manager, Session and Project Mark web pages, an email link to the OPUS Projects
Team always appears providing a convenient method to ask questions or make comments. The
manager may receive more than one reply from NGS staff depending on the subject of the email.
1.3.1 Notices
Notices about OP and, very rarely, a message specific to a project (no other project will see these
specific messages) may appear at the
top of the Manager, Session and Project Mark web pages. An
email link to the OPUS Projects Team will appear with any notices and messages so that follow-up
questions can be asked if needed.
1.3.2 Results Selection Menu
Below the web page’s banner (and any notices) is a pull down menu to select from a list of the solution
results available (Figure 1.7). Broadly, there are three categories: network adjustment, session
solutions, and OPUS-S solutions. As work in a project progresses, displaying all types of results
simultaneously becomes confusing. This menu provides a simple “filter” to help emphasize the results
of most interest.
1.3.3 Project Map
Figure 1.7 - Types of Solution Results Available
The manager, session and project mark web pages are built around a Google Map Services™ interactive
map to help orient users within the project and its geographic region. As project members upload
observation data to the project through OPUS, icons representing the project marks will appear on the
map. CORS stations used by OPUS during its processing of the project data will
be added to the project
at upload or can be added to the project later. Different icons are used to reflect a mark’s status in the
project.

icon action
A legend defining each icon type is shown just above the map (Figure 1.8).

For Project Marks:
A
green, open circle icon means the preferences set by the project manager have been met.
The project mark icon may be green immediately based on the OPUS-S
solution, or become green based
on the session solution, or network solution.
An
orange, barred circle icon (with a line through it) means that the preferences set by the
manager have not been met in processing using this projects mark data. This most often occurs with the
initial OPUS solution submission; less commonly from session processing. This condition does not
prevent the project mark’s data from being used in the project.
A
grey, crossed circle icon means that the project mark was not included
in the processing
results being displayed.
A
red, crossed circle icon notes an error with the project mark. This condition is seldom seen
but signifies a more serious problem with the project mark’s data or solution.
For CORS:
A
blue with
yellow trim icon means that the CORS data have met the preferences set by the
manager.
A
yellow with
blue trim icon means that the CORS solution result does not meet the preferences
set by the manager. This condition does not prevent the CORS data from being used in the project.
A
grey icon means that the CORS was not available or not included in the results being
displayed.
For Baselines:
Once a session solution completes, the baselines defined in the processing appear on the map. Each
session processed will automatically be assigned a different color. This
provides the Manager with an
intuitive view of multiple sessions presented on the map display. Similarly, after a network adjustment,
the baselines defined in the constituent session solutions of that adjustment will be shown as blue lines
on the map.
Within the map display to the upper-left, there are typical zoom controls (+/-)
and controls to zoom specifically to the project’s 'Marks' or 'Marks & CORS'. At
the upper-right corner of the map (Figure 1.7) you may set the map background
as either Terrain (digital elevation model), Satellite (satellite imagery if available),
or Map (towns, streets & highways). You also have the option to click
and drag
(pan) the map to view nearby areas.
Holding the cursor over a project mark icon will cause the icon to “brighten”
(lighten in color) and the project mark’s ID to appear (Figure 1.9). Clicking
(typical left mouse button) a mark icon on the map will cause information about the data files associated

with that project mark to appear in an information 'bubble'.
At the top of the bubble, the mark ID is
given. If the mark is a project mark, the ID acts as a convenience link to navigate to the summary web
page of that mark. A table listing all of the uploaded data files for a particular project mark is also shown
in the bubble (Figure 1.10 , 1.11). More than one file for a mark means data observed
at the mark is in
multiple sessions. Note that the antenna name and ARP height associated with each file are also shown
for the record. The project team member who uploaded the files is assigned as the ‘OBSERVER’. Their
name is a convenience link to send them an email message.
