Welcome

WinADCP is a software package for use with RDI Self-Contained Acoustic Doppler Current Profilers.  This software package supports both the Narrowband and the Broadband/Workhorse Binary Output Data Formats.

In general, WinADCP gives the user a visual sense of the entire set of data.  It also allows the user to zoom in on a portion of the data for closer analysis.

WinADCP has two main graphic display forms.  The form located in the upper right portion of the screen is called the Whole Set.  The form located across the bottom half of the display is called the Sub Set.  Each of these forms displays a portion of the entire data set as a color contour.  In addition to the color contour, Sub Set displays the user selected Profile, Series, and Ancillary data.

Help file revised April 16, 2003


System Requirements

WinADCP requires the following:

•	Windows 95, Windows 98, Windows NT 4.0 with Service Pack 4 installed, Windows 2000, Windows XP

•	Pentium class PC 233 MHz (350 MHz or higher recommended)

•	32 megabytes of RAM (64 MB RAM recommended)

•	6 MB Free Disk Space plus space for data files (A large, fast hard disk is recommended)

•	One Serial Port (two or more High Speed UART Serial Port recommended)

•	Minimum display resolution of 800 x 600, 256 color (1024 x 768 recommended)

•	CD-ROM Drive

•	Mouse or other pointing device


Overview

	NOTE.  Move your cursor over sections of the graphic and click to go to the description.


Whole Set

The Whole Set form is displayed in the upper right-hand portion of WinADCP.  When a file containing a Binary Output Data Format is opened, the entire set of the selected data type is displayed as a color contour located within the Whole Set form. Note: Only 256 ensembles are actually shown.  The data set is decimated (only every nth ensemble is used) before it is displayed and the statistics are calculated.

Mouse Control:

By holding down the SPACE bar and then pressing the LEFT mouse button, the user can drag the mouse to select a portion of the entire data set.  When the mouse button is released, the selected portion of the Whole set is marked by a blinking box outline.  The blinking box outlines a set of data called the Selected Set.  A second blinking box is also created when the mouse is released.  This second box is striped or solid depending on your graphics card.  The solid blinking box marks a region of data called the Sub Set.  The width of the Sub Set box may not be as wide as the Selected Set box.  The width of the Sub set is dependent upon the Options Ensembles setting selected from the main menu.

Shown below is an example of the Whole Set contour display.  The Sub Set contour display is identical except it does not show the Selected and Sub set ensemble numbers.

	NOTE.  Move your cursor over sections of the graphic and click to see a description.


Sub Set

The Sub Set form is displayed across the bottom half of the WINADCP window.  The Sub Set is broken up into three display sections:

Color Contour Chart

Profile Chart

Series and Ancillary Chart

Dragging the splitter lines with the mouse, while pressing the left button controls the size of the three display sections.

	NOTE.  Move your cursor over sections of the graphic and click to go to the description.


Subset Color Contour Chart

The Color Contour chart, located in the upper right hand portion of Sub Set, is basically identical to the Whole Set form.  The main difference is that it displays a selection from the entire data set.


Profile Chart

The Profile chart, located on the left side of the Sub Set form, displays a user selected ensemble in several two dimensional (2D) charts.  Each of these "sub charts" contains a different data type taken from the ensemble.  The user can select the profile ensemble by double clicking the left mouse button just above or just below the Sub Set color contour.

Tip

Use the left and right keyboard arrows to scroll through the ensembles.  Use the Animate menu to automatically scroll through the data file.  To quickly select an ensemble, double-click a point just above or below the Sub Set color contour plot.


Series Chart

The Series and Ancillary chart, located in the lower left-hand portion of Sub Set, displays user selected bins of user selected data types.  Also the user may select any of the ancillary data types for display in this chart.

The candle chart shows the statistical information about the series chart.  Use the Options, Chart Options menu to select the Averaging Interval.  The candle chart will be centered on the averaging interval.

•	The red line is the mean

•	The middle rectangle shape is the Standard Deviation

•	The long line shows the minimum and maximum values

Double-click the candle chart to display the Series Trend and Residuals chart.

Tip

Use the up and down keyboard arrows to scroll through the bins. Use the Animate menu to automatically scroll through the data file.  To quickly select multiple bins, double-click a point just to the left or right of the color contour plot on the Sub Set color contour plot.  Double clicking the same point will unselect the bin.


Series Trend and Residuals

The Series Trend and Residuals chart gives you a tabular statistic display of the selected data.  You can select a portion of the Time Series and apply a filter to sort the signal from the noise.  Use the Options menu, Chart Options, Series tab to select the averaging interval.


Information

The Information form contains useful data about the selected file and how the ADCP was setup when the data were collected.


Viewer

When the Mouse is positioned over a point within the Sub Set color contour charts, data associated with the bin and ensemble are shown on the Viewer form. If the Viewer is not visible, select the Window menu and click on Viewer.  A sample of the Viewer is shown below:

Most items are self-explanatory, however the ARRAY data in the center requires explanation. There are three rows of data:

1.  The top row contains Velocity data (V).  The first value is -462, this is the Eastward velocity component in millimeters per second.  The 95 is the Northward followed by the Vertical, error, Magnitude, and Direction of the velocity.

2.  The middle row contains Echo Intensity data in counts.  The 150 is Beam 1’s Echo Intensity followed by Beams 2, 3, and 4.  The last value (149) is the average of the four Echo Intensity values.

3.  The last row contains Correlation data if the ADCP is a Broadband or WorkHorse otherwise Spectral width for the Narrowband ADCP. If the data are not available then zeros are displayed.

Example Data Viewer with MicroCAT data.

	NOTE.  Lat/Lon and MicroCAT data will not be visable unless the data was collected.


Track Vector Time Series

The Track Vector Time Series window displays two current vectors: one along a selected track and the other orthogonal to it (90 degrees).  The user can select three different tracks: Navigation, Bottom, and Projected.  Navigation and Bottom use actual data contained within the ADCP ensemble.  The Projected angle is input by the user.

An application where this display is useful is in cable laying.  Ocean currents across the path of a ship tend to pull a cable off to the side.  Information about current magnitude and direction relative to the ship track helps to guide the ship for better cable placement.

	NOTE.  Clicking anywhere on the Track Vector Time Series display will display the Chart Options menu, Series tab.  Choose the bins to display by selecting the bin box on the list.   The  Track Vector Time Series display will only show data if in the Chart Options Series tab at least one bin has been selected.  If no bins are selected, then when you select Trend under the Utilities menu nothing will happen and in the Track Vector display there will be no data plotted.
The Track Vector Time Series window has its’ own menu.

Exit – Exits the Track Vector Time Series window.  To display the window again, click Window, Track Vector.

Animate – Choose Go to animate the chart.  Stop will stop the animation and Rewind will rewind the chart to the beginning of the file.

Projection – Choose between Bottom Track, Navigation Track, or Manual.  If you select Manual, you can select your own projection angle.

Reference – Clicking Reference will display the Chart Options menu, Processing tab.  Choose a reference from the list.

Display – Clicking Display will let you choose the Units, and Font for the display.  Selecting Time Origin on Left will toggle the time origin being displayed on the right to the left side of the display.

	NOTE.  The Animation and Reference menus are disabled on the Track Vector window when the Monitor mode is enabled.  All other menus are available.
	NOTE.  Negative range numbers are shown when the system is downward facing (bins are below transducer).  If the system is upward facing the range numbers are positive.


File Menu

Use the file menu to open binary output data format files.  The last four opened files will be listed at the end of the file menu.

MultiFile

File Open

File Save Selected Set

File Save Sub Set

Exit – exits WinADCP


MultiFile

Binary Data Files that have segmented consecutive file names (i.e. DEMO001r.000, DEMO001r.001, DEMO001r.002) will be read in as one file if MultiFile is enabled.  If MultiFile is disabled, then only the selected file will open (i.e. DEMO001r.000).

WinADCP is compatible with VmDas multi files.


File Open

When Open is selected from the File menu, a file directory dialog box is displayed. The operator is expected to select a file that has a Binary Output Data Format.

TIP

To quickly open a data file, you can "pass" a file name to WinADCP by dragging the file onto the WinADCP desktop icon (you must first create the desktop icon).  Another way to quickly open a data file is to click Start, Run.  At the open prompt, type WinADCP.exe "Filename.ext".


File Save Selected Set

When Save Selected Set is selected from the File Menu, a file directory box is displayed. Enter a unique file name and then click the save button.

Caution

If the file name already exists then the file will be written over.

Note

If the file name is the same as the currently open file then the Selected Set of data is not written to the file.


File Save Sub Set

When Save Sub Set is selected from the File Menu, a file directory box is displayed. Enter a unique file name and then click the save button.

Caution

If the file name already exists then the file will be written over.

Note

If the file name is the same as the currently open file then the Sub Set of data is not written to the file.


Edit Menu

The Edit menu has the following selections.

Max Ensembles

Max Ensembles, under the Options menu, is used to set the maximum number of ensembles shown in both the Sub Set, Color Contour and Series charts.


Animate Menu

WINADCP animation of ADCP data is the process of moving through a data set one ensembles or bin at a time while updating the various charts. When the end of the data set is reached the animation stops.

There are three types of animation in WINADCP:

1. Contour - The Sub Set, Color Contour is continually stepped half of it’s width. In other words, the first and last ensembles of the Sub Set are increased by (LastEnsemble-FirstEnsemble)/2. The data from the ensembles are read in, from the disk file, and the screen is updated. This "stepping" continues until the end of the data set is reached.

2. Profile - The Profile ensemble is incremented by one, the data are read in, and the screen updated. When the profile ensemble number is equal to the last ensemble of the Sub Set the animation stops.

3. Series - The Series selected bin(s) are incremented by one and the screen is updated. When the last selected bin is equal to the last bin of the data set, the animation stops.


Export Menu

Clicking the main menu item "Export" brings up the WINADCP Export Options dialog box. There are three styles of export:

1. Contour - Allows the selection of one data type, the first/last ensembles, the first/last bins, and the file format.

2. Profile - Allows the selection of many data types, one ensemble, the first/last bins, and the file format.

3. Series/Ancillary - Allows the selection of many data types, the first/last ensembles, the first/last bins (of the series data), and the file format.

The MAT file output has a MATLAB compatible binary format. From MATLAB type "load filename.mat" then type "who".  Column = Bin and Row = Ensemble. A list of variables for each output format is shown.

	NOTE.  If you are exporting navigation data form a data file collected with WinRiver, make sure to check the WinRiver box.  This lets WinADCP know where to look for the navigation data.
Tip

To quickly select bins, use the All or None buttons.

When the file size increases (due to real-time data collection in another program such as VmDas) Monitor will automatically reread the file at selected intervals and display the contents.  When Monitor is enabled and the file size is changing, all menu items except Monitor will be unavailable.  You can change the interval by clicking Monitor, Interval.  Enter the monitor interval in seconds.

	NOTE.  You can have multiple copies of WinADCP running on one computer.  If you want to Export while in the Monitor mode, simply load another copy of WinADCP.


Binary Output Data Format

A compact data structure that is output from an ADCP. Two formats are supported in WINADCP, the older Narrowband and the more recent Broadband/Workhorse. Refer to the respective user manual for a detailed description.


Whole Set

The form located in the upper right portion of the screen that displays the entire set of data for a user selected data type.


Selected Set

A subset of the Whole Set. The first and last ensembles of the selected set are shown in the upper right hand corner of the Whole Set color contour. The Selected Set position within the entire data set is graphically shown with a blinking line box that outlines the region.


Standard Deviation (S.D.)

The positive square root of the variance.

Variance = [ ∑x^2 -  (∑x)^2 / n ] / (n-1)

where:

∑x  = sum of all the data in the set

∑x^2 = sum of all the data squared in the set

n = number data points in the set


Sub Set

The form located across the bottom of the display screen displays the sub set data. This data is a portion of the data displayed on the Whole Set form. The first and last ensembles of the sub set are shown in the upper right hand corner of the Whole Set form. The Sub Set position within the entire data set is graphically shown by a blinking box that covers a portion of the Whole Set color contour.


Color Contour

A three dimensional (3D) display of ADCP data. The ‘x’ axis is time/ensemble. The ‘y’ axis is bin/range from the ADCP transducer. The ‘z’ axis is displayed as a unique color for each value from the data set.


Profile

A group of regular spaced data separated into bins. The bins are separated in space vertically from the face of the ADCP transducer.


Series

A bin or sample of data from multiple ensembles, which, when linked together, form a series. A single series might have 200 data points e.g.: Bin 2’s Velocity Magnitude starting at Ensemble 1000 to Ensemble 1199.


Ancillary

Ancillary data shows other sensors that the ADCP may sample and/or average over the duration of the ensemble. e.g.: Pitch, Roll, Heading, Temperature, etc.


Ensemble

A set of data that represents the average over an interval of time. Each ensemble has a unique number and a time stamp that corresponds to the time of the first sample. The data set contained within the ensemble has other information about the ensemble, a set of  profile data, and data from other attached sensors.


Bin

A position at a fixed range in front of the ADCP transducer where a measurement is taken.


ADCP

Acoustic Doppler Current Profiler


Data Type

One of many types of data stored in an ADCP ensemble. e.g. Velocity Magnitude, Echo Amplitude, Correlation, etc.


Data Type Title

In this example VELOCITY MAGNITUDE is the selected data type.


Average Value

The average the all the data shown plus it’s standard deviation.


Y-Axis Scale

The left side scale is in meters. For an upward facing ADCP the range values are positive, the range nearest the ADCP is at the bottom of the chart. For a downward facing ADCP the range values are negative, the range nearest the ADCP is at the top of the chart. The right side scale is in BinsBin. Bin 1 is always nearest the ADCP. The Grid is aligned with range scale.


Z-Axis Scale

The complete range of colors is shown in the small box located above the color contour. Three numbers are directly below it. The leftmost number is the minimum and the rightmost number is the maximum. A color directly above a number represents that number. In the example shown above: Blue is 0 mm/s, Red is 1824 mm/s, and Green is 912 mm/s.  Data whose value is less than the minimum is shown as Dark Gray. Data whose value is greater than the maximum is shown as White. Black is reserved for Bad data values.


X-Axis Scale

The bottom scale is Ensemble number increasing from left to right. The top scale is time from the first shown ensemble, increasing from left to right. The Grid is aligned with the time scale.


Selected Set Ensembles

The two numbers following Sel: are the Ensemble numbers that bound the Selected Set.  The Selected Set is outlined in a blinking solid box on the contour graph.


Sub Set Ensembles

The two numbers following Sub: are the Ensemble numbers that bound the Sub Set.  The Sub Set is outlined in a striped (or reverse video on some monitors) blinking box on the contour graph.


First Ensemble Information

Three lines of information about the ensemble are shown. The topmost line contains the first ensemble number of the data set, in this case ensemble 1. The second line contains the date of the ensemble. The third line contains the time of the ensemble. The date and time are the moment at which the first sample of the ensemble was taken.


Last Ensemble Information

Three lines of information about the ensemble are shown. The topmost line contains the last ensemble number of the data set, in this case ensemble 3556. The second line contains the date of the ensemble. The third line contains the time of the ensemble. The date and time is the moment at which the first sample of the ensemble was taken.


Change the Size of a Chart

There are several ways to change the size of a form.

1.	Drag the splitter lines with the mouse, while pressing the left mouse button to stretch the size of the three display sections.

2.	Use the Minimize, Maximize, and Close window control box located in the upper right corner of each form.

3.	Use the Window, Align Forms menu to make all forms visible.  This will turn on all closed windows and return the forms back to the default settings.


Compare Two Data Files

1.	Start WinADCP.

2.	Open the first data file.

3.	Open another session of WinADCP.

4.	Open the second data file.  You can arrange the windows as needed to compare the data.


Export Data

1.	Click Export.  The Export Options control box will display.

2.	Click on the Contour, Profile, or Series/Ancillary tab to select the type of graph to export.

3.	Select the file type (TXT = text, MAT = MatLab).

4.	Select what bins, ensembles, and data types to export.

5.	Click OK.

Note

To quickly select bins, use the All or None buttons.


Open a File

1.	On the File menu, click Open.

2.	Select the data file to be opened.  You can open BroadBand, NarrowBand, or WorkHorse raw binary data files.

3.	Click Open.

Note

Binary Data Files that have segmented consecutive file names (i.e. DEMO001r.000, DEMO001r.001, DEMO001r.002) will be read in as one file if MultiFile is enabled.  When you save the Subset or Selected set, it will be saved as one file.  Make sure you use a unique name to avoid overwriting a data file.

TIP

To quickly open a data file, you can "pass" a file name to WinADCP by dragging the file onto the WinADCP desktop icon (you must first create the desktop icon).  Another way to quickly open a data file is to click Start, Run.  At the open prompt, type WinADCP.exe "Filename.ext".


Print a Chart

1.	On the Edit menu, click Copy.

2.	Select either the Whole Set or the Sub Set.

3.	The chart will be placed on the Windows clipboard.

4.	Open the graphic program (or Word) and select Edit, Paste.

5.	Use the graphic program (or Word) to print the chart.

Tip

If you use the Edit, MSPAINT menu the Whole Set or Sub Set will be placed as a Bit Map image on the Windows clipboard and will open the Microsoft Paint program.  In Paint, select Edit, Paste to display the Bit Map.

Note

The shortcut to the Microsoft Paint program expects the program to be in the default directory C:\Windows.


Save a Subset File

1.	On the Whole Set color contour plot, use the Zoom feature to select the portion of the Whole set to be displayed in the Sub Set color contour plot.  You can use the zoom feature on the Sub Set color contour plot to further zoom in on the data.

2.	On the File menu, click Save Sub Set.

3.	Give the file a unique name.  WinADCP does not add an extension type to the file.  To organize data files, you may want to add the .000 extension.

4.	Click Save.

Caution

If the file name already exists as a closed data file, then the file will be written over. You will be prompted if it is OK to overwrite the file.

Note

If the file name you select is the same as the currently open file then the Sub Set of data is not written to the file.

The Sub Set has a limit of 8,192 ensembles.

If the Binary Data File that was opened had segmented consecutive file names (i.e. DEMO001r.000, DEMO001r.001, DEMO001r.002) when you save the Sub Set, it will be saved as one file.  Make sure you use a unique name to avoid overwriting a data file.

The format of the Sub Set file is the same as the raw ADCP Binary Data File format.  Sub Set files may be opened with other RDI Software.


Save the Selected Set

1.	On the Whole Set color contour plot, use the Zoom feature to select the Selected Set.

2.	On the File menu, click Save Selected Set.

3.	Give the file a unique name.  WinADCP does not add an extension type to the file.  To organize data files, you may want to add the .000 extension.

4.	Click Save.

Caution

If the file name already exists as a closed data file, then the file will be written over. You will be prompted if it is OK to overwrite the file.

Note

If the file name you select is the same as the currently open file then the Sub Set of data is not written to the file.

The Selected Set does not have a limit on the number of ensembles.

If the Binary Data File that was opened had segmented consecutive file names (i.e. DEMO001r.000, DEMO001r.001, DEMO001r.002) when you save the Selected Set, it will be saved as one file.  Make sure you use a unique name to avoid overwriting a data file.

The format of the Selected Set file is the same as the raw ADCP Binary Data File format.  Selected Set files may be opened with other RDI Software.


Turn Off the Locator Boxes

1.	On the Options menu, click Chart Options.

2.	Click on the Contour tab.

3.	On the Appearance box, remove the check box by Locators.
