APRS SYMBOL OVERLAY and EXTENSION TABLES in APRS 1.2 3 Apr 2017
---------------------------------------------------------------------
BACKGROUND: Since 1 October 2007, overlay characters (36 per symbol) are
allowed on all symbols. Since the master symbol document,
http://aprs.org/symbols/symbolsX.txt page only has one line per symbol
character this overlay list gives us thousands of new symbol codes.
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
\[ - \[ is wall cloud, but overlays are humans. S[ is a skier.
\h - Buildings. \h is a Ham store, "Hh" is 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
CONSISTENCY: 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 couldn't 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 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.
ADDITIONAL OVERLAY PROPOSAL: 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.

Anyone can use any overlay on any of the overlayable symbols for any special
purpose. We are not trying to document all possible such overlays. The purpose
of this document is to help keep a list of 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...
