SYMBOLS.txt 7.9.7            APRS DISPLAY SYMBOLS

The character after the latitude "N" in an APRS position report is a TABLE
character and the character following the longitude "W" is the APRS symbol
character.  The TABLE character selects one of two symbol tables or may be
used as a numeric overlay over some symbols as follows:

        TABLE    RESULT            
         /       Primary   symbol Table  (Mostly stations)
         \       Alternate symbol table  (Mostly Objects)
         0-9     Alternate OVERLAY symbol with 0-9 overlayed
         A-J     Alternate OVERLAY symbol with A-J overlayed (!* also)
        
Press F1-S in APRSdos to see these symbols.  The numeral "3" is overlayed 
on the following symbols which accept the alphanumeric OVERLAYS.  THese 
will only show on APRS78 or later.

  CIRCLE, SQUARE, CAR, TRUCK, VAN, DIGIS, GATES
  Civil-Defense(RACES), NWS sites, WX stations, Triangle

SYMBOLS WITH STAND-ALONE GPS TRACKERS:  Stand-alone TNC trackers which
transmit raw GPS have two methods of selecting their symbol.  First, by
the following default SSIDs:

  SSID  SYMBOL               SSID  SYMBOL
  ----  -------------        ----  ------------------
  -0    Dot                  -8    Ship (power boats)
  -1    Ambulance            -9    Car
  -2    Bus                  -10   Motorcycle
  -3    FireTruck            -11   Balloons
  -4    Bike                 -12   Jeep
  -5    Yacht (sail)         -13   RV
  -6    HELO                 -14   Truck
  -7    Aircraft             -15   Van

Secondly, you may now specify the symbol in the TO address of your 
packet using the TO CALLSIGN of GPSxyz.  The X points to a subgrouping
and the Y is the actual symbol.  Z is an overlay character if used.
Notice that this method results in a one-for-one correspondence for all
numeric and alphabetic symbols of both upper and lower case.  The symbol
table has been expanded to include these XYZ letters for all symbols
even though only a very small number will be used for GPS trackers.

AREA SYMBOLS!  You can define BOX/CIRCLE/LINE or TRIANGLE areas in all
colors, either open or filled in, any size from 60 feet to 100 miles. 
Simply move the cursor to the location, press HOME, move the cursor to the
lower right corner of the AREA and hit INPUT-ADD-OBJECTS-AREA.  Enter
the type of area, and color.  NOTE that AREA shapes can only be defined
by selecting the upper left corner first, then the lower right second. 
The line is an exception.  It is still top to bottom, but the lower point
can be to the left of the beginning point.

   These AREAS are useful for real-time events such as for a search-and-
rescue, or adding a special ROAD or ROUTE for a special event.  Be cautious
in using the color fill option, since all other objects in that area that
occur earlier in your PLIST will be obscured.  AND you do NOT know the
order of other stations P-lists. 

AREAS FORMAT: The new format for specifying special areas uses the CSE/SPD
field to provide the additional information as follows:

$CSE/SPD...  Normal Field description
lTyy/Cxx...  Where:  l (lower case L) is the symbol for "LOCATION SHAPES"
                     T is the Type of shape:  0=circle, 1=line, 2=elipse
                                              3=triangle 4=box
                                              add 5 to these => color-in
                     C is the color from 0 to 15.  For colors geater than
                       9, the / is replaced with a 1.
                    yy is the sqroot of the latitude offset in 1/100ths
                    xx is the sqroot of the longitude offset
                       
These offsets are ALWAYS positive to the right and down, except for the
special case of a lower right quadrant line, these are given the Type of
6 and are drawn down and to the left.

HURRICANES, TROPICAL STORMS and DEPRESSIONS:  These symbols will be
differentiated by colors red, yellos, and blue.  Additionally a radius
of Huricane and also Tropical storm winds will also be shown if the
format detailed in WX.txt is used.

SYMBOLS ON MAPS!  APRS can also be permanently embedded in maps.  To embed
a symbol in a map, simply make the first four characters of the label be a
# followed by the dual symbol character, followed by a hex number from 1
to F that indicates the color for the symbol.  The remaining 8 characters
can be used for a conventional label at the same location.  An example are
the VORTAC nav-aids in Alaska.  The Anchorage VORTAC appears as ANC on all
maps below 128 miles. The label entry is #\VFANC,LAT,LONG,128.


VALUE SIGNPOSTS:  These used to be called MILEPOSTS but have been renamed
to avoid conflict with the MILE-MARKER function in APRSdos.  These VALUE
Signposts display as a yellow box with a 1 to 3 letter overlay on them.
You specify the 1-3 letter overlay by enclosing them in braces in the
comment field.  Thus a VALUE Signpost with {55} would appear as a sign
with 55 on it.  This was designed for posting the speed of traffic past
speed measuring devices.  They can be used for any purpose.  But to avoid
cluttering the map, they ONLY appear at 8 miles and below AND they do
not show any callsign or name.  Only the yellow box and the 3 letters.
Select them from the OBJECT menu under VALUE...
