With Digital Atmosphere you are not stuck having to use one set of map
colors, line styles, and fonts for everything. Obviously when you want to use a
different color set, this means spending a lot of time making tedious changes.
Digital Atmosphere allows you to manage sets of colors, fonts, and line
settings. These sets are known as styles. A style is
identified by a plaintext name and a filename (all styles are stored in the
\styles directory under Digital Atmosphere, without exception). To change the
color settings, use the Preferences > Styles panel. Advanced users
may edit the files directly; this will not hurt anything if a plaintext editor
such as Notepad or MS-DOS Edit is used.
Listed here are the various codes that appear in the edit window. Above all,
be sure you pick Save when you are done, or your changes will be
- This is a predefined code that marks the
parameter type for internal use. It cannot be modified.
Parameter - This is a predefined code that
is used to provide a plain language explanation of the parameter for that row.
It cannot be modified.
R, G, B - These are color codes, which must be a whole number between 0 and 255. The R
column is for red, G is for green, and B is for blue. To pick orange, for
example, you would set R to 255, G to 128, and B to 0. You do not need to use
these columns. A vastly simpler input is available simply by clicking on the
color swatch to the right of the R, G, and B columns. If you do wish to enter R, G, and B
values, the following resource may help:
http://www.cloford.com/resources/colours/namedcol.htm . Do not enter hex
(hexadecimal) values; they will not be recognized.
Color swatch - Click on the color swatch to
select a different color. In the popup window, a crosshair will show the
current color value. Move it around or change the values to pick a new color.
The value of R, G, and B will be filled in automatically for you.
Contour type - Indicates the purpose of this
contour. It cannot be modified.
Unit - Proper entries are as follows. Do not mixmatch units or the
program will ignore the setting and use a default unit. Units marked with *
cannot be changed.
Temperature . . .
. . . deg f, deg c, deg k
Moisture . . . . . . . .
Relative Humidity . . . percent
Horizontal Velocity . . knots, mph, m/s
Velocity . . . ub/s (microbars per second)
Height . . .

Pressure . . . . . . . . mb, hpa, kpa,
Precipitation Totals . . inches, mm
Base - Determines the base value that the
intervals are based off of. For example, if you use an interval of 5 degrees,
a base of zero will give 0, 5, 10, 15, 20, 25.. degrees. If you use a base of
2 degrees, you'll get 2, 7, 12, 27, etc. Always reduce the base to the lowest
common denominator (as close to zero as possible).
Interval - Represents the contour step interval
(the numerical difference between each contour).
AI - Automated interval. If y is entered, Digital
Atmosphere will override the base and interval settings and choose the ones
that will give the clearest view of the data field.
Style - Indicates the linestyle that will be used
to draw the contour. Acceptable values are solid, dash, or dot. Radar echoes
must be either solid, clear, bdiag, fdiag, cross, crdiag, horiz, or vert.
MAKING A NEW
At some point you may not be happy with just editing the default styles. When
you want to create a new style, click the New... button. You will see a panel
- Enter a plaintext name. Choose any phrase that
will readily identify the map to you. A brief phrase without any brackets
should be used.
- Filename for this map style. The file shown here
is what the filename will be on your hard drive. This will be filled in
automatically when you choose a plaintext name. However the edit box gives you
the opportunity to override the filename. Only alphanumeric characters and
dashes are allowed.
- Style template filename (optional). Normally the
new color settings will be extracted from the \styles\master.stx file. If
you'd like to clone a different file, choose it here.
- CREATING STYLE FILES MANULLY: You can create your
own style files manually in a text editor, as long as the filename ends with
*.sty, resides in the \styles directory, and conforms to the style formats
shipped with Digital Atmosphere in this directory. Incorrect configurations
may produce an error in Digital Atmosphere and prevent fields from being
Clever use of styles can allow for interesting
maps like this one.
