APRS SYMBOL OVERLAY and EXTENSION TABLES in APRS 1.2 17 Jun 2018
|
|
------------------------------------------------------------------------
|
|
|
|
|
|
BACKGROUND: Since October 2007, overlay characters (36/symbol) are
|
|
allowed on all symbols. This allows thousands of uniquely specified
|
|
symbols instead of the original 188 (94 primary and 94 alternate).
|
|
But the master symbol document, http://aprs.org/symbols/symbolsX.txt,
|
|
only has one line per symbol. So this added overlay list below gives
|
|
us thousands of new symbol codes.
|
|
|
|
17 Jun19: Added several overlays for RAIL symbol
|
|
03 Apr17: Added Methane Hazard symbol "MH"
|
|
13 Feb17: Added Ez = Emergency Power (shelter), Cars: P> = Plugin
|
|
S> = Solar powered. Moved Ham club C- to Buildings Ch.
|
|
Added C- to house for combined renewables and added R%
|
|
Renewable to power plants
|
|
|
|
18 Oct16: Added G,Y,R for Flood gauges + N for Normal.(on H2O symbol)
|
|
Added DIGIPEATERS
|
|
22 Mar16: Added A0 overlay circle for ALSTAR nodes and V0 for VOIP.
|
|
Combined echolink and IRLP. P& for PSKmail node. W& for
|
|
Wires-X (was W0 for WiresII). Ya for Yaesu C4FM repeaters
|
|
|
|
Update 29 Oct 2015: Reorgainized list to Alphabetical Order.
|
|
+ Added many new Balloons (due to lost DoD radar Blimp yesterday)
|
|
+ Confirmed D^ for Drones was already in there since 2014
|
|
+ Added R^ type aircraft for remotely piloted
|
|
+ Added S^ Solar Powered Aircraft
|
|
+ Noticed all new category \= is availalbe. Had been shown ast
|
|
APRStt, but that was changed in 2009 to overlay BOX symbols.
|
|
|
|
UPDATES/REVISIONS/CORRECTIONS:
|
|
|
|
2014 Added numerous OpenAPRS symbol. Changed Da to DSTAR from Dutch
|
|
ARES. Added Subs to ships and lots of Aircraft overlays.
|
|
2013 Added ship overlay Jet Ski. Ham Club as C overlay on House, C-
|
|
2011 Added T and 2 overlays for TX 1 and 2 hop IGates
|
|
Added overlays to (;) Portables Added Radiation Detector (RH)
|
|
2010 Byonics requested (BY) and added #A to the table
|
|
2009 Added W0 for Yaesu WIRES and APRStt symbol to overlayed BOX (#A)
|
|
2008 Added RFID R=, Babystroller B], Radio#Y, skull&Xbones XH
|
|
|
|
|
|
DEPRICATION AND MAJOR REVISION: 25 Mar 08 Modified several Alternate
|
|
Symbol codes for expanded Overlays. The following alternate base
|
|
symbols were redefined so that the basic symbol could take on dozens
|
|
of unique overlay definitions:
|
|
|
|
\= - Had been undefined
|
|
\0 - Several overlays for the numbered Circle
|
|
\A - (BOX symbol) APRStt(DTMF), RFID users, XO (OLPC)
|
|
\' - Was Crash Site. Now expanded to be INCIDENT sites
|
|
\% - is an overlayed Powerplant. See definitions below
|
|
\H - \H is HAZE but other H overlays are HAZARDs. WH is "H.Waste"
|
|
\Y - Overlays for Radios and other APRS devices
|
|
\k - Overlay Special vehicles. A = ATV for example
|
|
\u - Overlay Trucks. "Tu" is a tanker. "Gu" is a gas truck, etc
|
|
\< - Advisories may now have overlays
|
|
\8 - Nodes with overlays. "G8" would be 802.11G
|
|
\[ - \[ was wall cloud, but overlays are humans. S[ is a skier.
|
|
\h - Was Ham store, Now Overlays are buildings "Hh" Home Depot, etc.
|
|
|
|
|
|
4 Oct 2007. ORIGINAL EXPANSION to OVERLAYS ON ALL SYMBOLS
|
|
|
|
In April 2007, a proposal to expand the use of overlay bytes for
|
|
the extension of the APRS symbol set was added to the draft APRS1.2
|
|
addendum web page. The following document addresses that proposal:
|
|
|
|
http://aprs.org/symbols/symbols-overlays.txt
|
|
|
|
For details on Upgrading your symbol set, please see the background
|
|
information on Symbols prepared by Stephen Smith, WA8LMF:
|
|
|
|
www.aprs.org/symbols/symbols-background.txt
|
|
|
|
CONSISTANCY: Since the objective of APRS is consistent, reliable
|
|
communications at the local level, there has been a hesitance to
|
|
making significant changes to the APRS symbol set. The Integrity
|
|
of APRS depends on everyone seeing the same information at the
|
|
same time. Frequent changes to the symbol sets can actually
|
|
undermine that integrity and operational utility of APRS and end up
|
|
with worse outcomes due to miss-communications than the lack of any
|
|
particular symbol might suggest.
|
|
|
|
OVERLAY HISTORY: When the overlay symbol set was first defined for
|
|
the original APRS back in 1995, it had the potential to expand the
|
|
APRS symbol set from the 94 original primary symbols to a secondary
|
|
set that could each have as many as 36 diffeernt overlays on each of
|
|
those secondary symbols up to almost 3500 combinations. But some
|
|
authors then could not easily implement these overlays, except by
|
|
one-by-one exceptions to their code.
|
|
|
|
For this reason, a compromise was made with those authors and then
|
|
eventually written into the APRS spec to limit overlays to only a
|
|
small subset of alternate symbols. Those original overlayable
|
|
alternate symbols were labeled with a "#" and called "numbered"
|
|
symbols. (UIview requires "No." in the symbols.ini file)
|
|
|
|
STATUS OF OVERLAYS 1 OCTOBER 2007: the APRS symbol set was limited
|
|
to about 94 symbols and only had a few remaining unused symbol
|
|
codes that had not yet been defined:
|
|
|
|
OF THE 94 Primary Symbols. The following were available:
|
|
10 symbols (/0 - /9) that mostly look like billiard balls now
|
|
4 symbols /D, /J, /Q, /z were undefined or TBD
|
|
2 were reserved
|
|
|
|
OF THE 94 Alternate Symbols. The following were available:
|
|
3 undefined series \=, \Y, \Z which could do 36 overlays
|
|
8 series \1 through \8 that can support 36 overlays each
|
|
3 reserved series.
|
|
|
|
BASIS FOR OVERLAY EXPANSION: But any of the other 79 alternate
|
|
symbols could all have multiple (36) overlays if they can make sense
|
|
with the existing underlying basic symbol that we have been using for
|
|
that basic alternate symbol. That is, any new definition of a
|
|
previously unused overlay character will have undefined results on all
|
|
prior APRS systems and should be used with caution. But the symbol
|
|
set is extensible with these cautions. (See the Proposal that would
|
|
expand the APRS symbol set to over 3200 at the bottom of this
|
|
document.)
|
|
|
|
|
|
SYMBOL OVERLAY TABLES: This document will keep track of all
|
|
definitions of overlays on all ALTERNATE symbols. Although these
|
|
overlays were originally intended to just overlay a displayable
|
|
single character on a basic symbol, there is no prohibition against
|
|
taking the combination of a symbol and specific overlay, and then
|
|
letting that define a new graphic just for that combination.
|
|
|
|
The following tables will attempt to keep track of these and
|
|
any other useful generic applications of overlay characters.
|
|
|
|
AMPLIFIED some existing ALTERNATE SYMBOL Overlays: (Aug 2014)
|
|
change Flooding #W to include Avalanche, Mudslide/Landslide
|
|
Update #' name to crash & incident sites

more common such definitions that have more universal use and for

which multiple definitions would lead to confusion.

Future APRS code writers should be aware of where we are going:

PROPOSAL TO ASSIGN MANY MORE BLOCKS OF SYMBOL SETS April 2007
|
|
--------------------------------------------------------------------
|
|
www.aprs.org/symbols/symbols-overlays.txt
|
|
|
|
In the initiative to upgrade APRS symbols, we are wasting some
|
|
very valuable OVERLAYABLE symbol subgroups with a few nailed
|
|
down legacy weather symbols. We are proposing to consolidate
|
|
some of these Weather symbols to open up much more space. Since
|
|
this is the first time we have considered actually CHANGING some
|
|
symbol definitions, this can cause problems out there for some
|
|
users of some legacy systems.
|
|
|
|
That is why I am posting this plan to the APRS community. If we
|
|
do this, XASTIR and UIVIEW will be able to download new symbol
|
|
definitions. But some legacy clients that do not operate from
|
|
external symbol files will show the wrong symbols for these. If
|
|
users of those systems forsee some serious problems with the
|
|
re-arrangement of these symbols, let us know the specific impact
|
|
and your ideas for a workaround..
|
|
|
|
The symbols that would be impacted are as follows:
|
|
|
|
First, consolidate all of the visibility symbols into the old
|
|
SMOKE symbol and change its meaning to "VISIBILITY", and then
|
|
differentiate them with the overlay characters.
|
|
|
|
"\E" (existing smoke) the symbol with no overlay
|
|
"HE" (an H overlay) will mean Haze
|
|
"SE" (an S overlay) will mean Smoke
|
|
"BE" (a B overlay) will mean Blowing Snow was \B
|
|
"DE" (a D overlay) will mean blowing Dust or sand was \b
|
|
"FE" (an F overlay) will mean Fog was \{
|
|
|
|
Another category is to expand the RAIN symbol to make it kinda
|
|
like lots of angled dots coming from the sky, but with an open

center so that we can use overlays for a number of common
|
|
PRECIPITATIONS. The consolidations would be:
|
|
|
|
"\`" (existing Rain) would be the symbol with no overlay
|
|
"R`" (an R overlay) would mean Rain
|
|
"F`" (an F overlay) would mean Freezing Rain was \F
|
|
"H`" (an H overlay) would mean Hail was\:
|
|
"D`" (an D overlay) would mean Drizzle was \D
|
|
"E`" (an E overlay) would mean slEEt was \e
|
|
"S`" (an S overlay) would mean Snow was \*
|
|
Etc. and other particulates coming from the sky
|
|
|
|
Next, I propose expanding the existing RAIN SHOWER "\I" symbol
|
|
to look like some kind of cloud symbol with specks in it that
|
|
can be overlayed. (It needs to look different from the next
|
|
CLOUD symbol). It can then consolidate these symbols:
|
|
|
|
"RI" (an R overlay) would mean Rain Shower
|
|
"SI" (an S overlay) would mean Snow shower was \G
|
|
"LI" (an L overlay) would mean Lightening was \J
|
|
Etc. and other things related to clouds
|
|
|
|
Next, I propose expanding the existing CLOUD symbol to allow
|
|
definition of any number of different types of cloud. This
|
|
needs to also look like a cloud but a different shape and allow
|
|
for overlays (Maybe this cloud is clear):
|
|
|
|
"\(" is the existing cloud symbol (would have no overlay)
|
|
"P(" with P overlay would mean partly cloudy was \p
|
|
"W(" with W overlay would be a wall cloud was \[
|
|
"F(" would be Funnel cloud, but the original "\f" will also be
|
|
retained for now
|
|
|
|
All of these initiative will free up a lot of overlayable symbol
|
|
GROUPS each of which can suport up to 36 different overlays in
|
|
each group for the future:
|
|
|
|
#H for 36 new Hazards (was only Hail)
|
|
#[ for 36 new human symbols (was only Wall Cloud)
|
|
#\ for 36 new GPS or navigation equipment
|
|
#B TBD. \B was only blowing snow now is BE
|
|
#b TBD. \b was only blowing dust/sand now is DE
|
|
#{ TBD. \{ was only fog now is FE
|
|
#* TBD. \* was snow only now is S`
|
|
#: TBD. \: was hail only now is H`
|
|
#D TBD. \D was drizzle only now is D`
|
|
#F TBD. \F was freezing rain only now is F`
|
|
#e TBD. \e was sleet only now is E`
|
|
#G TBD. \G was only Snow shower now is SI
|
|
#J TBD. \J was only Lightening now is LI
|
|
#p TBD. \p was only partly cloudy now is P(
|
|
|
|
Of course future code can fully draw each of these overlays as
|
|
distinct special symbols in any way they want.
|
|
|
|
I especially want to hear from Dale Hugley who
|
|
is a resource for weather, and Stephen Smith who will have to
|
|
draw them for Uiview. And others with a stake in this...
