for viewing a cross section plot in ISIS Mapper.
You will see Select Shapefile window offering you to select any of the shapefiles currently loaded in
the TOC. After the cross section file has been specified you will see the Cross Section Plot window in
which you need to specify the ISIS 2D results variable for plotting. As a result, a graph diagram as
shown on Figure 6 should be on your screen.
Figure 6: Cross section plot window. The available data to load can be selected using the tick boxes in
the left column.
If the cross section graph is not needed to be permanent then the user can obtain a quicker result
using the Measure tool, located under the View tab towards the top left of the Mapper interface. The
measure tool allows the user to draw a line using a similar functionality to the shapefile editor.
On selecting the Measure button, the cursor will change. The user should then left click to start the
line and double left click to complete the line. The X-Section tool can then be accessed immediately,
as described above. The user will not be asked to identify a shapefile, as the measure line will act as a
substitute.
More details about how to perform these operations and the tools used is contained in the ISIS
Mapper manual.
4. Animation of the 2D Model Results in ISIS Mapper
The 2D model results can be animated in ISIS Mapper. For this you need to make sure that the 2D
Model Results are loaded into ISIS Mapper and are highlighted in the TOC. To launch the Animation
Toolbar the user should right click the appropriate layer in the TOC and select Animate from the
menu.
In order to start the animation, you need to click on Run Animation button and in order to finish
the animation you need to click on Stop Animation button . It is possible to have only either of the
scalar results (Water Level or Depth) or vector results (Flow or Velocity) animated at the same time.
Scalar results are normally shown using a layer changing its dimensions and vector results are shown
by arrows.
It is also possible to record the animation into a video file, which can be played on a video player (.avi
file).
