It would seem that if the APRS spec says that WGS84 is the datum of APRS
(not just the default, but the only), then it's put squarely upon the
shoulders of the client program authors to ensure that any maps it reads in
are re-projected or otherwise corrected into WGS84, or that any data it
gets from the APRS system (RF or IS) is translated to whatever datum the
map display is using.
Unfortunately, these dealing with datums and re-projection is tough stuff,
and if you're just making some program to draw stations on maps, one may
not dig deep enough to even know that there are these things called
'datums'.
So theoretically, everything on the 'public' side of APRS (RF and IS)
should be WGS84, and anything internal to the client program can be
whatever the author (or user) chooses, so long as it stays internal.
More practically, Bob B. might say that the original design of APRS was for
local tactical something-or-other. If it's local, and everyone uses the
same setup (software, maps, etc.) then it may not matter (much), so long as
you can see the relative positions of everyone involved in your 'tactical
event'.

Uh -- disregard! It was the old "tabs or spaces" question in
aprsxtra.txt.

Subject: Trouble with PM3.5 on laptop?
From: "Jacob Tennant" <k8jwt@ntelos.net>

I am running WinAPRS2.4.5 with PM3.5 on a IBM ThinkPad770 with
98mbRAM,P233MMX.
For some reason I can't seem to get down to my local area map level? When I
click to zoom in, I get the hourglass to wait and then it locks up and I
have to do a END TASK exit to WinAPRS.
Any ideas?
If you tell me to upgrade, What is the newest version I can use with PM3.5?
Ain't gonna spend $xx.xx for PM5!

I got it fixed for now???
My laptop has a removeable CD drive and it must not have made a contact as
I removed it and reinserted it and now it works?
Sorry for the bandwidth. . .
Still wonder what the highest version I can use with PM3.5?

I have to agree. The majority of my maps are in polyconic Albers equal
area projection - the standard for the state of California. I think it's a
lot more reasonable to either provide a reprojection facility, or require
that the user reprojects the maps before use, than to have every client
support a thousand different data ('data' being the proper plural of
'datum') and who knows how many different projections.

WinAPRS 2.5.1 (May 2001 version) is the latest that works with PM 3 or PM
3.5. The latest WinAPRS 2.6.1 (June 2002 version) is only setup to use PM
5, but it doesn't work right yet. Do not use WinAPRS 2.4.6 (bad bug if
connected to internet)!
Hope this helps.

I was just received MapPoint 2002, and I noticed that there is a street
missing (it has only been there SIX YEARS) and ia major exit off I-75...
Does anyone know if there is a way to upgrade this?
No, I have not gone to the microsoft site yet, adelphia.net (my ISP)
have been having brain farts all day, and now the DHCP server is down -
again... So I need ot go in via a dial up and I hate slow dialups.
