Good point. I'll have to see how they do it. Perhaps the current position
can be queried on a periodic basis, which would allow us to do it more
easily.

Frank Warmerdam would be the guy to ask if you're looking for the do-all
be-all map format. He handles a bunch of the open-source libraries for
handling maps, like Shapelib, GDAL/OGR, libgeotiff, libproj, etc. He'd
know.
We're planning on heading in a different direction though. It'll be speedy
when we get there.

At first I thought I replied incorrectly to this thread, but I may be wrong.
I didn't see it posted all day. I have been out of the state on vacation,
and I do not check the sig when on vacation.
What ever I can do to correct this problem, if my error, I will.
I have not changed anything till today after Clay and I exchanged some
ideas. I updated UI-View to the latest version. I hope this corrects the
problem.

I just ran a check on FINDU of the stations I normally would be I-gating. I
put an asterisk instead of an ssid to see if my setup was doing it too. I'm
using Ui-View 32 V2.03. I didn't find any extra ssids that weren't supposed
to be there. I don't think it's Ui-View causing it. Currently connected to
APRSwest.net 14580.

Yeah, you will. The US military are just now understanding the benefits of
moving maps, staying within a track, etc.
Along with the USN, they are now seeing the significant time saving during
sea to land assaults with them.

The original findU server is now experiencing a second life as an APRSworld
map server, Jim has gotten the computer configured, and we are starting to
test it. So far, the only place you will see it through findU is with the
breadcrumb cgi (and therefore the track cgi). When called without a geo
parameter, it will fetch a map from the new server, by default it covers
roughly a 2 degree square:
http://www.findu.com/cgi-bin/track.cgi?call=k4hg-8&start=9999
You can change the scale of the map with the new degree parameter:
http://www.findu.com/cgi-bin/track.cgi?call=k4hg-8&start=9999°ree=.1
http://www.findu.com/cgi-bin/track.cgi?call=k4hg-8&start=9999°ree=3
Go ahead a try this out, let us know of any problems. As with his other map
server, because only US data is available for free, the detailed maps are
limited to the US, for the rest of the world the server just generates a
coarse outline map.
Thanks to Jim for making this work!

Perhaps you could explain the steps that a non-technical user would have to
go thru to install XAstir.
1. Assume that a non-technical user needs to install Linux, or Cygwin. How
long would that take?
2. Is there a Windows like install routine that can install a working
executable under every version of Linux?
3. If there is no install routine, what steps must a novice linux user take
to get it up and running and how long do you estimate it will take him to
get a working program?

It only takes a few minutes to install most Windows programs. No need find
the needed libraries and compile source code into an executable using
cryptic command line instructions. Just stick the CD into a windows CD
drive and away you go. Until linux can provide similar ease of install, most
"old=duffers" and non-technical users will continue to use Windows.

What I'd really like to do for field teams would be to have a ruggedized
color handheld with topo and orthophoto maps, connected by bluetooth to a
GPS/TNC combo in the backpack, and set up so that it can receive map objects
like search assignment areas. If I had several thousand to invest in
hardware and software licensing and 40 hours a week to work on it, I'm sure
I could come up with something. Not gonna happen any time soon, I'm afraid.

Sorry, sometimes the little things count. I just found the reply and it was
my error.
Sorry to clog the sig, but I hate to make a mistake.
So, if the error is mine, with the ghost SSID's, I would like to correct the
problem.

Ask wa7nwp w.r.t. Cygwin. Bill?
Personally I'd skip Cygwin/Windows, as you'll get much better performance
out of Linux, or FreeBSD, or Solaris, or MacOSX. You know, one of the
operating systems that has the Unix features built-in already.
Buy a boxed set of SuSE Linux 9.0 or 9.1, follow the instructions. You'll
be running it quicker than if you did a Windows install on the same box,
with fewer reboots for the actual install. One to boot Linux from the
install media, one to boot Linux off the hard drive when you're done.
It's VERY easy to install Linux to a hard drive. I don't know how long
it's been since you tried to install Linux before, but they've made it
really simple these days. If you're starting from a blank drive or willing
to waste everything already on the drive anyway. If you want to do a dual
or multi-boot system, you have to proceed a bit more slowly. ;-)
>2. Is there a Windows like install routine that can install a working
>executable under every version of Linux?
For Xastir? No. There could be though. We'd have to make an RPM binary
for each of the operating systems. Some people are doing that already, but
for the main project we choose not to. The reason is that compiling it for
each system customizes it for the libraries you have installed. If you
need additional map libraries, you install them, do a quick recompile, and
you have the new functionality. One size fits all.
We're not talking about your typical APRS program here BTW. This one has a
lot of capability. Some people want everything compiled in (like me), and
therefore install all of the optional libraries. Some people don't, and
make do with just the basic Xastir or perhaps one or two of the optional
libraries.
>3. If there is no install routine, what steps must a novice linux user take

If you are running one of the operating systems for which a binary is
available, it's a matter of minutes.
If you're not, it's a matter of a few more minutes. The INSTALL files
takes you through the simplest install, which gets you a running Xastir.
After that it takes you through compiling in support for additional map
libraries. You'd also have to have installed a compile environment and a
few "devel" packages in order to be able to compile Xastir on the box. It's
a simple process, and only needs to be done the first time. The xastir
mailing list is the quickest place to get answers if you run into problems
there.
Any of the new users want to give an estimate on how long it took to get
running, then up to speed on how to use it?

Ever heard of RPM packages? .DEB packages? apt-get? These problems have
been solved.
There's another project in the works to make a Linux bootable CD with
Xastir pre-installed, and maps. That would probably be the starting point
for a lot of these Unix-scared people that don't think they can run
anything but Windows. I don't know what the schedule is for that project
though. I'm not working on it.
What other APRS program runs on Win95 through WinXP, FreeBSD, MacOSX,
Linux, and Solaris, and gives you 115 map formats, all from the same source
code, which you can compile yourself in a few minutes? It's pretty amazing
if you think about it. If you don't like how something works, you talk to
one of the twelve developers and try to get them to change it, else you
change it yourself and submit a patch to them. We get a lot of bug fixes
and new features added that way.
