- APRS DISPLAY SYMBOLS
-
-
- As of version 1.16, APRS supports 28 or more different display symbols
- for differentiating objects on the map. An additional dozen WX symbols
- were further added in version 3.07. The obvious advantages of such
- symbols are to show at a glance what type of packet stations are represented
- by the various callsigns shown on the maps. Another improvement is the
- addition of two large symbols, one for thunderstorms and one for hurricanes
- that cover a much larger geographical area. Although these symbols are still
- placed on the map at a very precise location, their large symbol areas are
- much more representative of the very large objects that they represent! The
- maps are therefore much more realistic when used in the SKYWARN application.
-
- To make these symbols backward compatible with earlier versions of APRS,
- the delimiter after the Longitude in the standard APRS POSITION report was
- changed from the fixed (/) character to a variable SPECIAL character to
- represent the different symbols available. Printable ASCII punctuation
- characters are mostly used to represent each of the display symbols.
- Although these special characters are automatically inserted into the APRS
- position reports, they are specified here for manual TNC stations. Remember
- that any TNC can still show up on APRS maps and displays as long as a
- properly formatted APRS position report is placed in the TNC BText. By
- placing one of these special characters as the delimiter after the LONGITUDE
- field, a station with only a dumb terminal can control his appearance on
- other APRS displays. For more information on manually formating APRS reports
- using only a dumb terminal, see the README.DUM file. The following table
- describes the symbols available and the special characters used to represent
- them. Notice that there are several generic shapes without designated
- descriptions, so that users can tailor their symbology to the particular APRS
- net application. If you have any suggestions for other symbols, please send
- them in...

-
- Note that Weather stations will always show up as blue. This overides all
- other APRS colors. Weather stations will also not be dead reckoned since
- their course and speed indicates wind conditions and not station movement.
- I also made the sun show up as yellow overriding all other color conventions.
