Overview
Streamline-SBP-SS (formerly named Bathy-2000W Shore Station')is designed to process
and perform technical analyses of Bathy 2000 and 2000P sub-bottom data
and to provide the user with easy-to-use visualization and archive management
tools. Streamline-SBP-SS operates as a "Shore Station"; providing post-processing
functionality and visualization of data previously collected by Bathy 2000/2000P
systems. The shore station version permits scientists to view the sub-bottom data after
it has been offloaded from the Bathy 2000P system. Streamline-SBP-RT is the expanded version of Streamline-SBP-SS that supports integrated real time operation with a Bathy 2000/2000P system.
Streamline-SBP-SS incorporates features commonly found
in a Windows environment including standard menus and toolbars, movable and resizable windows, clipboard compatibility, the
ability to save screen images to Bitmap (BMP) files, and graphic controls.
Streamline-SBP-SS also takes advantage of the increased graphic display resolution
and speed of Windows graphic display adapters to provide greater detail
when viewing sub-bottom data.
Streamline-SBP-SS supports printing images of any
data display window to Windows compatible
printers. Hardcopy is supported for all Windows printers including
grey scale and color. In addition, Streamline-SBP-SS includes a custom
parallel port interface to all models of Syqwest's Thermal Graphic Recorder
(TDU) product line and EPC 9800 Series printers allowing continuous grey scale hardcopy output of sub-bottom
records.

Overview
Streamline-SBP-SS includes five main display
and control utilities: The Tools Control, System Status Monitor, Remote
Control/Status, Sub-Bottom and Amplitude Display windows. At any
time you can rest the mouse cursor over any object within the graphic user
interface to get a "tool tip" that describes the content of the data field.
The main window and all child windows are fully resizable (with the exception
of the Remote Control/Status window) and may be moved freely about the
screen. A description of each follows:
I. System Status Monitor - The System
Status Monitor displays system status and general parameter information
for each data record. All information is updated in the System Status
Monitor for each acoustic data record stored in the Syqwest (ODEC) formatted SEGY
file.
The value displayed in any field on the System Status Monitor in Replay
Mode represent the values when the acoustic data record was archived.
Referring
to the figure of the Streamline-SBP application interface above, the parameters
shown in the System Status Monitor include the following:
| Sample Time |
Date and time stamp for
the current acoustic data record. |
| Geographic Position |
Geographic position of the
current acoustic data record. The display format of the longitude/latitude
parameters is user-selectable (e.g., Decimal Degrees, Degrees-Decimal Minutes
or Degrees-Minutes-Decimal Seconds). Click the arrowed buttons to
the right of the longitude/latitude display fields to select a display
format. |
| Ship Speed |
The ship speed is read from
the SEG-Y data file and represents the speed in knots. |
| Estimated Heading |
The estimated heading is
a calculated value based on the longitude/latitude information between
two successive acoustic data records. This value is only an estimate,
at best, and should not be used for navigation purposes. |
| Depth |
Digitized depth value in
current measurement units for the current acoustic data record. The
channel 2 display fields will be filled with zeroes unless the data file
contains dual channel information. |
| Noise |
Measured noise displayed
in units of decibels. |
| Echo |
Measured acoustic echo strength
displayed in units of decibels. |
| System Messages |
Displays any system or operator
messages. The System messages field also displays Streamline-SBP-SS system,
annotation and error messages. |
| Alarm Status |
Visual "Shallow Water" and
"Bottom Lost" status indicators with audio warning. The audio
warning is activated only if the system running Streamline-SBP-SS has a sound
card and speakers connected to the system. The status indicators
are displayed as follows:
a. Dull green – Idle Mode.
b. Bright Green – Status
is ok.
c. Red – Alarm condition
activated. |
II. System Control Center - The System
Control Center displays processing controls and transmit/receive values as they were set during data acquisition.
-
Display and processing controls include utilities
to modify data presentation in the sub-bottom and amplitude display windows.
Utilizing the Display and Processing Controls, the user may modify:
-
Depth range (increments of 10 measurement
units) and phase selection with auto phasing option;
-
Time-varied gain;
-
Specially designed contrast and intensity
gain filters that enhance data clarity and presentation;
-
When replaying archived data (playback mode), Streamline-SBP-SS
displays the values of operational parameters as set during acquisition.
The parameters include (Note not all of the parameters and/or selections
described here are available on every Bathy 2000 or 2000P system):
-
Operation Mode (FM or CW modes);
-
Power Level;
-
Transmit Mode (Single ping, dual channel,
pinger, multi-ping);
-
Transmit Rate;
-
Pulse Length;
-
Sweep Band;
-
System Gain;
-
Sound Speed.
III. Sub-Bottom Display - The Sub-Bottom
Display window provides an animated scrolling view of sub-bottom data.
The window is fully resizable allowing users to expand the view to obtain
better graphic resolution. The selected color palette is shown at
the top of the form with increasing intensity from left to right.
In addition, the Sub-Bottom Display window provides the user, while replaying
archived data files, the ability to quickly scroll either forward or backward
in time. A sliding control and date/time display fields are used
to control the quick scrolling feature. Scrolling forward in time
by 1/8 of a screen is accomplished by clicking on the right arrow of the
scroll bar or 1/4 of a screen by clicking in the scroll area of the scroll
bar anywhere to the right of the scroll button. Backward scrolling
in time is accomplished by clicking the left arrow or clicking in the scroll
area to the left of the scroll button. You can also drag the scroll
button (Note that the scroll button graphically details the relative position
of record being displayed with the start of the scroll bar representing
the start of the file and end of scroll bar being the end of file) in any
direction to go to a particular record. The date time fields will change
as you drag the scroll bar button indicating the record you will move to
when you finally let go of the button by unclicking. The user may
also control the visibility of bottom tracking gates, event and annotation
marks, and grid lines and even use the slope tool to determine seafloor
slope.
IV. Amplitude Display - The Amplitude
Display details the magnitude of each data sample for an individual acoustic
return. The Amplitude Display will resize to be the same height as
the Sub-Bottom Display whenever the Sub-Bottom Form is resized and will
also move with the Sub-Bottom Display whenever it is dragged. Depth
range and phase window selection is also matched between the Amplitude
Display and Sub-Bottom Display.
V. Tools Control - The Tools Control
includes functions to control the operational state of the Streamline-SBP-SS.
You can rest your cursor over any toolbar button to get a "tooltip" that
defines the function of that button. Available functions include:
-
Open File - Use the standard Windows "Open
File" dialog to select files for replay or remote monitoring;
-
Search Functions - Use the search function
(available in replay mode only) to locate any data record by entering the
desired date and time or location (specified by longitude and latitude).
Upon locating the specified data record, playback of the data is resumed
starting at that record.
-
Pause - Pause the current operation;
-
Fast Forward - Available in replay mode only
this function cause the system to replay the data as quickly as possible.
-
Play - Replays data at the same rate as
it was recorded.
-
Step - Step one data record at a time (available
in replay mode only).
