3. Select a custom Color Scale.
Custom scales are defined by the system operator in the Color Setup utility. There are
up to 8 scales for each data type. These scales include the choice of color set, number
of colors, and data levels for each color.
The existing color scales remain intact in the software upgrades.
When installing fresh software, a default color scale and the choice Uniform are
available for each data type. In addition, the color scales Winter and Everything are
pre-configured for the reflectivity data types, for the purpose of matching varied
seasonal and application needs.
The Default color scale of the HClass data corresponds to the class set of the legacy
HydroClass. The HClass data type includes additional color scales PRECIP, CELLS,
METEO, and METEO-CELLS, which correspond to the multiple Classifier methods (and
their meaningful mergings) available in IRIS/RDA.
The choice of Uniform has a special meaning: you can interactively select the color set,
number of colors, and start and step levels. This is convenient for simple thresholding
out low and/or high data values, as well as for the simplest mergings of echo classes of
HydroClass.
4. If you are in uniform mode:
a. Select a Color Set.
Up to 4 named color sets are available. The color sets are defined by the system
operator in the Color Setup utility.
Typically you would define a Default set for positive valued data such as reflectivity;
rainfall rate, TOPS, VIL, and so on. You would also define a Velocity set to be used
for data that can be positive or negative such as velocity, ZDR or SHEAR.
b. Type the number of colors to place in the scale (range 2 ... 16) in Levels.
c. Type the start and step values in First Level/Step.
The start value is placed in the upper edge of the first color. Control over saturation
of the first and last color is taken from the Default color scale for the data type as
configured in the Color Setup utility.
5. To highlight a data interval to see if that data is on your display, select Highlight >
Enable and then Edit .
The Highlight Tool starts. See Highlight Tool (page 213).
6. Select File > Save to save your results.
The results are saved for only the window where you are working. You cannot aect
other windows. You may want to go to the other windows and make similar changes
and save them.
