<p><a NAME="DrawFreehandEditArea"></a><font color="#3333FF"><font size=+2>Draw
|
|
a Freehand Edit Area</font></font>
|
|
<p><font color="#000000">Use the Select Points tool to define an Edit Area
|
|
by hand. For more information see the section <a href="GFETrainingSpatialEditor.html#DefineEditAreabyHand">Define
|
|
an EditArea by Hand</a> in the GFE Training Guide.</font>
|
|
<p><a NAME="SelectFourZones"></a><font color="#3333FF"><font size=+2>Select
|
|
an Edit Area that includes four different forecast zones of your
|
|
choice.</font></font>
|
|
<p><font color="#000000">There are several way to accomplish this, but
|
|
the easiest is to select it from one of the cascading menus found in the
|
|
Main Menu bar, </font><font color="#FF0000">EditAreas->Zones->[zone name]</font><font color="#000000">.
|
|
Note that to accumulate the edit areas, you will need to put the Spatial
|
|
Editor into UNION mode by selecting the "+" from the button labelled "=".
|
|
For more detailed information, see the section <a href="GFETrainingSpatialEditor.html#LoadingNamedEditAreas">Loading
|
|
Named Edit Areas</a> in the GFE Training Guide.</font>
|
|
<p><a NAME="SelectElevationArea"></a><font color="#3333FF"><font size=+2>Select
|
|
an Edit Area based on a given elevation.</font></font>
|
|
<p><font color="#000000">Unless your site manager has already set up edit
|
|
areas based on elevation, you will need to do this from the Edit Area Query
|
|
Dialog. Select the button labelled "</font><font color="#FF0000">?</font><font color="#000000">"
|
|
on the tool bar. The Edit Area Query Dialog will appear. Next enter
|
|
your query using the buttons such as, "</font><font color="#FF0000">Topo
|
|
> 4000</font><font color="#000000">" (adjust the value based on your topography).
|
|
Once you have defined the query select "Submit". The query will execute
|
|
and a new edit area will be selected that matches the query you entered.
|
|
For more information on queries, see the section, <a href="GFETrainingSpatialEditor.html#EditAreaQueries">Edit
|
|
Area Queries</a> in the GFE Training Guide. For more infomation on the
|
|
dialog, see the section, <a href="ButtonBarDialogs.html#EditAreaQueryDialog">EditArea
|
|
and Query Dialog</a> in the Button Bar Dialogs document.</font>
|
|
<p><a NAME="SelectBasedOnDewpoint"></a><font color="#3333FF"><font size=+2>Select
|
|
an Edit Area that includes locations where the dew point is above a value
|
|
that you specifiy.</font></font>
|
|
<p><font color="#000000">This task is similar to the one above except that
|
|
this time you are using a different element to define the area.</font>
|
|
<br><font color="#000000">Make sure that the dew point weather element
|
|
is loaded into the GFE. Open the query dialog (by selecting the button
|
|
labelled "?") and define your query such as, "</font><font color="#FF0000">Td
|
|
> 45</font><font color="#000000">". Then select "Submit". You
|
|
should see a new edit area displayed in the Spatial Editor that corresponds
|
|
to your query. Note that when you animate or step frames the query
|
|
is re-run so that the edit area always reflects the currently displayed
|
|
grid. For more information on queries, see the section, <a href="GFETrainingSpatialEditor.html#EditAreaQueries">Edit
|
|
Area Queries</a> in the GFE Training Guide. For more infomation on the
|
|
dialog, see the section, <a href="ButtonBarDialogs.html#EditAreaQueryDialog">EditArea
|
|
and Query Dialog</a> in the Button Bar Dialogs document.</font>
|
|
<p><a NAME="SelectBasedOnWeather"></a><font color="#3333FF"><font size=+2>Select
|
|
an Edit Area that covers locations with a certain type of weather</font>.</font>
|
|
<p><font color="#000000">For this task, load the "Wx" weather element and
|
|
open the query dialog by selecting the button labelled "</font><font color="#FF0000">?</font><font color="#000000">".
|
|
Next define your query such as </font><font color="#FF0000">mask(Wx, ":RW:")</font><font color="#000000">
|
|
and click the submit button. The new edit area should match your
|
|
query. For more information on queries, see the section, <a href="GFETrainingSpatialEditor.html#EditAreaQueries">Edit
|
|
Area Queries</a> in the GFE Training Guide. For more infomation on the
|
|
dialog, see the section, <a href="ButtonBarDialogs.html#EditAreaQueryDialog">EditArea
|
|
and Query Dialog</a> in the Button Bar Dialogs document.</font>
|
|
<p><font color="#000000">Another way to select areas of the same weather
|
|
is to use the option available from the MB3 pop-up menu, "</font><font color="#FF0000">Select
|
|
Homogeneous Area</font><font color="#000000">". Selecting this option
|
|
will create a new edit area defined by the type, coverage and intensity
|
|
of whatever weather value the cursor is over when you execute "Select Homogeneous
|
|
Area". For more information, see the section, <a href="GFETrainingSpatialEditor.html#SelectHomogeneousAreabasedonValue">Select
|
|
Homogeneous Area based on Value</a> in the GFE Training Guide.</font>
|
|
<p><a NAME="MakeNewQucikset"></a><font color="#3333FF"><font size=+2>Save
|
|
an Edit Area in a Quick Set button, clear the Edit Area and restore it
|
|
with the same Quick Set button.</font></font>
|
|
<p><font color="#000000">For this task you use the Quickset buttons located
|
|
in the far right section of the button bar. Create an edit area either
|
|
by hand, from the Main Menu or a query. Then select "</font><font color="#FF0000">Q</font><font color="#000000">"
|
|
followed by any one of the numbers. Now clear the edit area by pressing
|
|
the button labelled "</font><font color="#FF0000">C</font><font color="#000000">"
|
|
and then select the same number button that you did earlier. Note
|
|
that the edit area that you just cleared has been redisplayed. This
|
|
operation works for edit area queries as well. Saving a query under
|
|
a QuickSet entry returns as a query when it is recalled. When an
|
|
edit area query is loaded and executed it always runs on the currently
|
|
displayed grid. See the section in the GFE Training Guide, <a href="GFETrainingSpatialEditor.html#SavingEditAreasasQuickSets">Saving
|
|
Edit Areas as QuickSets</a> for more information</font>

|
<p><a NAME="ZoomSpatialEditor"></a><font color="#3333FF"><font size=+2>Zoom
|
|
the Spatial Editor so that only a portion of your CWA is displayed.</font></font>
|
|
<p><font color="#000000">There are two different ways to zoom the Spatial
|
|
Editor display. One is to MB3 press and select the "</font><font color="#FF0000">Zoom
|
|
to</font><font color="#000000">" cascade menu and select one of the numbered
|
|
options. These numbers represent the final width of the display (in
|
|
kilometers) after the display zooms.</font>
|
|
<p><font color="#000000">A short cut allows you to zoom in and out using
|
|
the mouse buttons. Press and hold the SHIFT key on the keyboard and
|
|
click MB2 anywhere in the Spatial Editor display. Note that the display
|
|
zooms in one level. Zoom in further by clicking MB2 a few more times.
|
|
Now zoom back ou by again holding the SHIFT key and clicking MB1.</font>
|
|
<p><font color="#000000">For more information on zooming the Spatial Editor
|
|
display see the section, <a href="GFETrainingSpatialEditor.html#ZoomingtheSpatialDisplay">Zooming
