1.5.1 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 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.
1.5.2 Map of the Project Mark Area
Similar to the manager’s and session web pages, the project mark web pages include a
Google Map
Services™ interactive map to help orient users within the project and its geographic region (Figure 1.52).
However, because its uses are different, the map looks different than those on the other web pages.
A legend appears above the map (Figure 1.52 & 1.53). Clicking an icon type symbol in the legend will
hide/display those mark types on the map. The mark ID is also given in the legend. This is a pull-down
menu, one of
several such menus on the page, used to navigate to other mark web pages.
Figure 1.53 - Mark display options
Within the map display to the upper-left, there are zoom controls (+/-) plus three
preset controls to zoom to see '
This Mark’s' immediate vicinity, '
All Marks' or all
'
Marks & CORS' in the project. At the upper-right corner of the map (Figure
1.5.2), the map background can be set as either Terrain (digital elevation model),
Satellite (satellite imagery if available), or Map (towns, streets & highways).
Clicking on the map and holding the mouse button down will drag (pan) the map
to view nearby areas as the cursor is moved across the web page. Holding the
cursor over an icon without clicking will reveal the mark’s ID (Figure 1.54).
As is described in the legend for the map, four types of marks may appear on the map:
-A yellow “pin” identifies the location of the mark to which this web page refers.
-Gray pins show the locations of other marks in this project. Initially, the map shows only a
small area so other marks in the project may not appear until the map is shifted or “zoomed
out”.
-The standard blue with yellow trim icon identifies CORS. Again, the map shows only a small
area so the CORS may not appear until the map is shifted or “zoomed out”.
-Black triangles appearing in the map indicate the locations of nearby marks for which published
NSRS information exists in the NGSIDB. These published marks are not necessarily part of the
project, but are shown because they help form the reference frame like the CORS. However, if
this project mark has a PID, the published mark's icon will still appear,
but as a yellow triangle
(
), thereby indicating this association. Clicking on one of these mark icons reveals a pop-up
window displaying the mark’s datasheet (Sections
1.5.2.1
and
1.5.2.2
). Recall that a PID can be
associated with a project mark either when its data files were uploaded or by using the controls
on the projects mark's web page.

1.5.2.1 Standard Datasheet Pop-up Window
The banner for this window provides the mark’s
Permanent Identifier or
PID. Typical pop-up window
controls are located just below the banner: '
Help' and '
Refresh' buttons on the left; a '
Close' button on
the right. Below the controls, the datasheet is given.

1.5.2.2 Project Manager’s Datasheet Pop-up Window
If the project manager accesses a record mark page and views a published mark datasheet, then
in that window’s controls are included three special function buttons (Figure 1.55):
'Use Description' applies information from the datasheet to the
empty description elements
for this project mark. Restating, the published description can be applied to this mark,
but it will not supplant/replace information previously entered at upload or by the
project manager.
'Use Coordinates' replaces the a priori coordinates for this project mark (based
on the OPUS
solution) with the record mark’s datasheet coordinates.
Be aware that changing the a
priori coordinates for a project mark invalidates all existing project processing.
Changing the a priori coordinates for a mark should be done cautiously before any
processing is completed. If you choose to change the a priori coordinate you have
decided that the mark coordinate from the datasheet is BETTER than the coordinate
created when you uploaded your mark data to the project through OPUS. This would
be a very rare occurrence. USE WITH CAUTION!
'Use Description & Coordinates' is a simple convenience activating both the other controls
simultaneously.

1.5.3 Controls
The web page’s controls appear to the left of the map. Standard controls, Section
1.5.3.1
, are always
available, but additional controls are provided for the project manager, Section 1.5.3.2.
1.5.3.1 Standard Controls
Figure 1.52 shows the basic controls for an individual project mark’s web page.
1.5.3.1.1
Help, Back and Refresh
Help,
Back, and
Refresh buttons at the top of the controls. The
Help button is under development and
may ultimately provide the same resource as this document. The
Back button “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 session web page to be reloaded. Its action is
usually stronger than the browsers refresh button which may only bring up a previously cached version.
1.5.3.1.2
Show File
The
Show File button reveals a pop-up window for displaying solution reports. Across the top of the
window are controls (Figure 1.49 and 1.56). Standard pop-up window controls
appear at the top, but
instead of a single button at the top-center to initiate an action, this window offer a choice of available
reports: OPUS, session processing, or network adjustments. Below the controls is a header providing
the report’s name, its creation and download (current) times. Then the report is displayed.
Some browsers offer a print option by right-clicking (right mouse button) anywhere in the report. All
browsers should allow the report’s text to be copied and pasted into another file using the method
typical of the operating system. See
Appendix B for more information.
