Previous edition was 4 Oct 2007.

|

|
|
|
|
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:

|
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 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...
