3.27 XSECT: Cross Section
Figure 40 XSECT Configuration Example
XSECT is a volume scan product that shows the height cross-section along a user-definable
line.
The XSECT product is similar to an RHI in that it shows a range-height representation or
vertical "slice" of a radar parameter.
For XSECT, the cross section is constructed from a PPI volume scan. This means that if you
are running a standard volume scan at regular intervals, an XSECT can be constructed
without scheduling an RHI task.
Unlike RHI products, which are typically composed of about 100 elevation angles, the
resolution in an XSECT is limited by the number of elevation angles in the volume scan,
typically 10 ... 20. However, the 3-D interpolation used by the XSECT algorithm yields an
excellent representation of the height distribution of radar parameters. The algorithm also
corrects for earth curvature eects so that the height scale corresponds to the actual height
above your product reference height (usually sea level).
You can use the XSECT product in the following ways:
• For regions of interest, such as a watershed area or air terminal, you may configure an
XSECT as a standard product to slice through the area.
