Qimera Profile Dock

Profile Dock

The Profile Dock allows you to view a profile line over one to many surfaces in order to get detailed or comparative information along the line.  To entire profiling mode, click the  button.  Then left-click points on a surface to define your line segments.  End your profile by defining a final point using right-click.  You can also bring up a profile by performing a right-click-drag as you would in Fledermaus.  This will create a single segment profile from any currently active cursor mode.  If you start your profile off a surface, it will start once you are over a surface and will end if you extend the profile off a surface.  In order to create more than one segment, you must be in Profiling Mode.

Qimera will generate a unique color-coded profile for every visible Dynamic or Static surface in the current project.  If you don't want to see a profile plot, simply uncheck the surface in the Layers View.  In the example above, the same surface was gridded twice, where one surface had the line data shifted down by 2 meters. 

The plot surface displays the locations and spans the distance between each point using a vertical dashed line in the plot.  The vertical axis is the profile depth and the X-axis is the 2D distance along the profile.  As you move your cursor along the profile plot, you will also see several properties about that point displayed below the plot, including the 2D distance along the profile, the delta Z between the two surfaces (if exactly to surfaces are present), the 3D distance along the surface currently selected in the table (if any), and the KP value at the cursor position (if the project has an active route). As you move the cursor over the plot, the Depth  and Slope columns of the table will update to show the values for each surface at that point.

In the 4D View, the profile draws as a draped line on the topmost surface with a vertical curtain that extends up to the minimum depth.  White markers are also drawn at each segment endpoint.  A single red marker appears along the plot correlating to the location of the cursor in the plot area of the Profile Dock.

Profile Dock Toolbar

This button will change the color of the currently selected profile plot.

  Line Pattern Button

This button will change the line pattern of the currently selected surface.  If you click and hold the button, you will see a drop down list of the choices.  If you simply click, it will cycle to the next line pattern.  The choices are dots, dashed line, dot-dash line, dot-dot-dash line,  and solid line.  For more information, please see the section on the Time Series Multiplot.

  Delta Button

This button will compute the difference between 2 selected surfaces in the table view.  Once you select the 2 surfaces, click on this button to generate a "Difference" plot.  When you select the "Difference" entry from the table view, the Y scale will change for the plot showing you the vertical extents of the data. The difference scale can be set relative to the source data by selecting the newly created "Difference" profile and unchecking the 'Use Exaggerated Scale for Differences' profile menu item.  

  Zoom Out Button

If you have zoomed into an area of the plot, this button will zoom out to the extents of the currently viewed attributes.  All attributes share the same time axis.

 Explore Mode

This is the primary exploration mode of the tool.  As you move your cursor over the plot, the label in the lower left of the window will update to show the current time and value of the selected attributes.  A tracking ball will follow the location in time along the currently selected track in the 4D View.  If you click/drag the plot surface, you can pan around the data.  The mouse-wheel will zoom in/out of the plot. 

  Zoom Mode

When in zoom mode, simply click and drag an area of the plot to zoom into.  Click the Home button to return to the full extents of the data.  At any time, you can shift-click to drag the plot to a new location.  For more information on plotting surface navigation, see the appendix section found here.

  Measure Mode

This mode will allow you to measure along a profile.  First, you must select a surface from the table view.  Then left-click and drag in the plot area to measure between 2 points on the profile.  As you drag, you will see corresponding red markers indicating the start and end of your measure in the plot and 4D View.  Below the plot you will see specific details about the measurement.  These include 2D Distance, Surface Distance, Line-of-Sight Distance Line-of-Sight slope, and Delta Z.

  Point Size

This button will allow you to change the size of the plotted points and lines.  Sizes range from Small to XX-Large.  Clicking on the button will cycle to the next size.  Click and hold to get a drop down menu of sizes to choose.

  Profile Menu

Show Statistics

This setting turns on the statistics view for the currently selection profile.  It will show the minimum and maximum as solid lines, the +/- 1-Sigma as dashed lines and the average as a dotted line.  Value labels will appear on the right side of the tool.

Show Color Map

This will turn the color map fill of the currently selected profile on or off.

Export to ASCII

This will export to an ASCII file with data about the profile.  The default folder is the ~myproject/Export folder.  The ASCII file will contain Sample Point, 2D Distance, Easting, Northing, Depth and Surface Distance for each surface in the Profile Dock.  If the project has a route, the KP value of each point will be included as well.

A sample export is shown below.

Save Plot to Image

This will save the current Profile Plot to an image file.  The file type by default is PNG.  The default folder is the ~myproject/Export folder.  The first image below is the configuration of the Plot before export.  The next image is the exported image.  Notice that Qimera includes the color and line pattern legend.

Show Gridlines

This option will show/hide the grid lines in the plot area.

Lock Depth Scale

This will lock the current Y plot range (Depth) so that when you create a new profile over flatter terrain, it doesn't overly exaggerate small details.  This allows you to more easily see areas of high depth range.  If the new profile contains depths above or below your currently "locked" range, the range will be extended to encompass these new depths so that you don't have to zoom out to see them.

Clear Differences

This will clear the current difference plots from the Surface Table.  If you create a new profile, difference plots will be automatically cleared.

Use Exaggerate Scale Difference

With the box checked an exaggerated scale will be used causing the selected difference plot data to extend to the bounds of the plot. With the box unchecked the difference series will use the same scale as the two source items used to create the difference series. This item will only be enabled if there is a difference series created.
