Xastir gains the ability to save as JPG or PNG only by
ImageMagick/GraphicsMagick. We produce files in XPM format (X PixMap)
because it's native to X. To produce JPG or PNG, Xastir would need to add a
dependency on libjpg and/or libpng. Not necessarily a light undertaking.

Have you tried compiling ImageMagick or GraphicsMagick from source?

The TAMU system for mailing lists isn't technically Gerry's. The University
hosts a LISTSERV server that apparently is open to anyone. I recall years
ago there was a specific policy about who was allowed to have a list on it,
but I can't see that anywhere except one place that says the primary list
owner's email should be linked to the official university email account
(which is no problem for Gerry.)

http://listserv.tamu.edu/

This LISTSERV hosts thousands of lists and would not go down for any length
of time without immediate action.

Re: [Xastir] Radio frequency question from a simpleton

2007-07-19 Thread J. Lance Cotton
on 7/19/2007 3:40 PM Curt, WE7U said the following:
> I've always heard that you can't protect a protocol, but IANAL.

The typical way of protecting (in some sense) a protocol or standard is to
aggressively protect the copyright of the specification document. The actual
grouping of bits or whatnot that come about in the actual operation of an
electronic protocol or standard cannot be trademarked, copyrighted, or
patented, as far as I am aware.

But any creative "work" can be copyrighted and in fact is automatically
protected by U.S. copyright law upon its creation.

In the case of APRS, the only things Bob can legally protect are:

1) The trademark "APRS" and "APRS - (Amateur|Automatic) (Position|Packet)
Reporting Service"

2) The APRS Spec 1.0 and 1.1, though since those were created by a
committee, I don't know if Bob has exclusive rights to copy that document or
what.

A person *could* create a specification document (of original,
non-plagiarized information) that described a protocol compatible with APRS
and could give it a name other than APRS and it would be perfectly legal,
even if it would upset some folks.


Recall on APRSSIG the fluff when someone proposed/introduced/mentioned Scott
Miller's OpenTRAC protocol, which conveys much of the same information as
APRS, only organized and regularized a bit differently from APRS. The
central issue (with Bob) was that a different "protocol" would interfere
with APRS if used on the same frequency. The truth is that in the FCC's
eyes, APRS and OpenTRAC are both 20kHz (or thereabouts) wide AFSK FM
modulated data with carrier-sense method of collision avoidance. Even beyond
that minimal commonality, both APRS and OpenTRAC use identical (OSI Model)
Level 2/3 protocol of AX.25 on the air.

There's no possible way that OpenTRAC could interfere with APRS any more
than APRS interferes with other APRS operation.

In the end, it came out that Bob was worried that if people started using
OpenTRAC on 144.39 MHz, then folks using APRS-only programs might not see
all symbols on their screen that the packet-braaaping on the air would indicate.

Note: I don't hate Bob B. or APRS or anything or anyone else. I just get
annoyed by illogical arguments. Live long and prosper \V/

Assuming you started kissattach to connect the port named eoc to the serial

Xastir does need SUID, but not because of the serial port. Xastir needs SU
privileges in order to open the eoc ax.25 port.

Take a screenshot of the map area you like, and set up a .geo file that
references the corner points of the screenshot with the real locations under
those corner points.

Xastir cannot interface directly with external mapping programs, period.
Main reason is it's often against the terms of use for those mapping
programs, or the interface method is proprietary or costly.

I have a Zaurus, too. There is an alternate ROM system for it (openzaurus)
which comes in two flavors: Qt-based and X11-based. I've only tried the
X11-based one superficially, not with xastir.

Not sure if it's even worth it -- the model I have has 64M of RAM, and it's
split between ramdisk and working-memory. Various builds of the firmware can
change the ratio between working memory and storage, but I don't know how
well Xastir would work in such a small memory space.

Not currently configurable.  You'd have to change the code and

You could always write a short script to snag the files periodically
and save them somewhere else.  Could even smarten it up so that it
saves a file away only when a new timestamp occurs on one of the

Or, I don't know, there might be a program already installed on most Linux

Same channel. Don't worry -- it's just for testing purposes. Average TCP/IP

For some places in Europe I've heard it's accepted to run APRS

fine in the U.S. and Canda.  I'd be wary of running connected mode
packets or even unconnected mode TCP packets on the main APRS
frequency.  You're liable to get shot by the locals.


Not too many locals here. We've got about 5 active APRS users in the county.

It is just very convenient to give a quick ping on a known-working setup

Re: [Xastir] Mapping

2006-11-09 Thread J. Lance Cotton

on 11/9/2006 2:02 PM Stephen Brown Jr said the following:

At a bare minimum, I would like to have street level maps for a couple of
states and then expand to include the entire U.S.

What would be the best option based on what I want? Also, is there a good
tutorial or reference that explains all these different types of maps
available?


Shapefiles will probably give you the best bang for the buck and with a 
little effort on your part and maybe some help from the list, you can get a 
very nice looking and nice acting Xastir setup.


Shapefiles are a pure vector format, containing basically just a bunch of 
lines from here to there. A "shapefile" is actual a set of 3 files, often 
called the "holy trinity" by at least one GIS-type I've come across:

 a) map.shp
Contains the actual point data for the lines or points
 b) map.shx
I'm not certain, but I think this is an index of the .shp file to make 
searching quicker.

 c) map.dbf
A very important file; this is a simple flat database with a one-to-one 
matching with the line segments in the map.shp file. This is where metadata 
about the line segments is stored.


Xastir has a feature called dbfawk that allows you to define drawing styles 
(color, line width, and more) based on attributes in the .dbf file.


Tom Russo has a good tutorial on using dbfawk files in Xastir:
http://www.swcp.com/~russo/shape_web/tutorial.html
(I don't know if that's on the wiki -- but if not, it ought to be!)

With Xastir's map properties panel, you can set the minimum and maximum zoom 
levels at which a particular map will be drawn. (Using dbfawk files, you can 
even do this on a line-segment basis rather than a whole-file basis). This 
allows you to use less-complex, and therefore faster-drawing, shapefiles 
when zoomed out to a state or nation level, but switch to very detailed 
shapefiles when zoomed into a smaller area (county, etc.)


With dbfawk files and the shapefiles generated from the Tiger data 
(ftp://aprs.tamu.edu/pub/Xastir/Maps/TIGER/xastir.tamu.edu/index.html), you 
could have xastir's maps look exactly like the Tiger server maps - only MUCH 
quicker!


Using shapefiles, I was able to use the above maps for the whole state of 
Texas. This was good, but my county provides better quality map data (in 
shapefile format) that is more accurate, higher resolution, and more 
updated. So for my county, I use the county-provided map data and turned off 
that county with the Tiger shapefiles.

See result at: http://aprs.lightningflash.net/

I hope this gets you started by answering a few questions. All of use on the 
list will be more than happy to answer any more questions you have about 
maps -- we all seem to get pretty excited over Xastir's mapping capabilities!

Re: [Xastir] another map problem

2006-10-20 Thread J. Lance Cotton

Dave,

I'm forwarding this back to the Xastir list. I don't have debian apt-get 
experience, but I bet others on the list do and can help you with that part.

The website is still there? strange

What would your recommendations be - uninstall Xastir, and, if so what 
command line install switches would you use?


Or if I'm wrong about that - how would you recommend checking 
ImageMagick as both APT-GET INSTALL and Synaptic claim its the latest 
version?  There's no Man page either :(



Thanks

I can't seem to connect to that URL.

The "Support for these additional map types has been compiled in:"
you've
shown indicates that ImageMagick is not compiled in.

There was talk a while ago of converting the more recent files.  Is this still 
in the works (or should I say, are the folks who were going to do it still

interested)?



I think the administrator of the server had to take it down temporarily. I 
will try to find out if that is true.

Does that count CVS grabs? Probably not, eh?

How about:

I know there are other Unix SysAdmins on here too.
