The Marcotte Enhancement for the DMD Time Height Trend is and
implementation of a proposal from Mike Marcotte at the Lake Charles
Weather Service Forecast Offie.
The enhancement allows the user to draw ellipses proportional to the
major axis of a detected freature on the DMD Time Height Trend graph,
connect all values for the same tilt, connect all values of the same
volume scan, and add a legend for the ellipses. In oreder to give
flexibility to the user, the enhancement is implemented with a toggles
buttons for the following:
- Diameter Overlay
- Elevation Angles
- Volume Scan Poles
- Legend
The legend can be viewed only when the Diam overlay button is active.
Ther use can activate all four buttons for any DMD attribute that has a
time height trend.
Meeting notes:
- Ama started the UIWG by going throught the presentation
materials.
- The Marcotte Enhancement is accessed from the SCAN menu,
selecting Storm DMD Icons & Table:
- For a given attribute, place cursor over the value on the table
for the desired feature and click the right mouse button. The time
height trend plot appears. The new features of the enhancement allows
the user to draw ellipses whose big axis is proportional to the
diameter value in nautical miles, of the detected freature, connect all
values/ellipses of the same elevation angle, connect all
values/ellipses of the same volume scan, and add legend of ellipses to
help the user to aestimate the diameter size when viewing attributes
other than the diamter attribute.
- The DMD Time-Height Trend is displayed. Note the four toggle
buttons: Diam Overlay, Elev Angles, Vol Scan Poles, Legend. These
toggles be toggled on one at time, all toggles on, or in any
combination.
- This enhancement does not currently support sampling.
- When the legend toggle is enabled, the resulting legend
potentially can block some of the displayed data. The legend should be
repositioned elsewhere on the display. Remember though that this
information can be toggled off. When the user is familiar with the
tool, they will recognise the different sizes of the ellipses.
Currently, the legend is displayed near the oldest data. It was
suggested that the legend would be in a black box so as the overlaying
of information does not happen.
- Much discussion regarding the Volume scan poles in regard to the
time tick marks on the bottom of the display. The time tick marks need
to be more meaningful to the user. Should the Volume scan poles
extended to the time line? Group decided this was give misleading
information. Decided that one tick mark in time per Volume Scan, with
the beginning of the Volume Scan from the data base will be plotted
along the x-axis.
Action Items:
Here are the actions items from the UIWG meeting:
- Label elevation angles on both the right and left sides when the
evelation angles toggle is enabled.
- Need to label the other "Y" axis. Currently the axis is only
labeled on the left.
- Legend needs to be displayed in a black box so that
when overlaying other parts of the display there is
no confusion.
- "x" axis (time) shall have one tick mark in time per
Volume Scan, with the time displayed being the start of the
Volume Scan.
- User configuration will be saved so that when closing and then
reopening the applications, the user will not
need to reselect his/her options.
