Even if the rest of the protocol is never adopted, I like the symbol
scheme - I borrowed the general format from MIL-STD-2525. It's
hierarchical and provides more semantic information. The top level
categories should be added to very rarely so most new identifiers
will fall into existing categories and you can still tell, for
example, that a newly-created solar powered Prius symbol is a ground
vehicle and more specifically a car so your client can still display
a car, despite not having a more specific symbol.<br>

There are more and more opportunities to look at OpenTrac as a
place to solve the limitations of APRS fixed field and symbol use.
We really need to move in that direction.

<div dir="ltr" data-setdir="false">Just in my opinion, it
sounds like you're overloading the icons too much. One
station can't have two different symbols at the same
time. To quote from your telemetry example, if the
station has green battery voltage but the power amp is
overheating to red, what _one_ symbol will be reported
for that combination? You can't flip-flop back and forth
rapidly, because you'll clog the RF channel with
excessive packets, plus the RF channel isn't reliable,
so there is no guarantee that every single packet (with
every state change of the symbol) will get through to a
receiving station.</div>

<div dir="ltr" data-setdir="false">And where on the map
display are you going to simultaneously display _all_ of
your multiple weather station parameters for a single
weather station? That sounds like you would need a
custom tabular display with one row per station and one
column per parameter, which then could be color-coded
per ranges; I have a similar table in my YAAC
application for monitoring the quality status of weather
station parameters. But the station icon is for the
state/type of the station as a whole, not just one
parameter of it. Yes, for the flood gauge symbol codes,
they are color-coded for the flood level, but that's
really the only parameter a flood gauge station reports
(it's not a weather station or Echolink gateway or
anything else at the same time).<br>
