Interpolated Contours
from Radial Field Values
Q: Once I have run a radial field study how can I get
an interpolated contour from the field strength values?
A: A data base of radial field strength values is created when you
execute a radial or
contour study from
HDCoverage. You can use the
results in that data base to compute additional interpolated
field strength contours. The contour distances are computed from the
field strength values computed along the radials as described in the
Contour
Interpolation Calculation article.
From the TAP Area menu, select the "Contour from
Computed Field" option:
For TAP5 and earlier, from the TAP Coverage menu, select the "Contour from
Computed Field" option:
A list of the existing results data bases will
be displayed. Click on the selection button at the left of the
row to highlight the task with the radial field values:
In the "Results section, be sure the radial
field study is selected. (If other contours have been computed,
they will also be contained in the task results.)
Click the "Continue" button.
When the task is selected, the Interpolate Contour
form is displayed:
The "Source Task" section summarizes
the selected task, including any contours already contained in
the data base:
Enter the value (in dBu) of the new contour you
want to interpolate:
Select the level of detail (if any) you want to
save in a text file. The text file will be located in the WORK
subdirectory located below your TAP directory (such as C:\SWTAP\WORK)
and will be named Tnnnnnnn.TXT, where nnnnnnn is the task ID:
Click the "Continue" button to start
the contour interpolation.
When the interpolation is completed, a message
box is displayed. Click the "OK" button.
