Is there a way to have Xastir and the OpenOffice Calc / Excel application exchange the search sector areas and the current Probability of Success for visual presentation? That is, the operator would set up the search sector in Xastir using predefined sector names. Xastir would calculate the area of the sector and write those area values to the proper field in the spreadsheet. The operator would then perform the calculations in the spreadsheet and update the POS for that sector. The spreadsheet would then send the updated POS values to the note field of the sector for display in Xastir. A step further would be to shade the sector based on the current POS. I know _exactly_ what you're talking about, although there are several ways of doing the calculations via various spreadsheets or via stand-alone programs.

Are you asking what the different circles mean? I was able to figure this
out by looking at the APRS spec and the source code in db.c --- I was unable
to find any documentation of these circles anywhere else.
They're the radius of various wind speed ranges as predicted by the NWS.
The red circle is the reported (or predicted) radius of hurricane force winds,
the green the radius of gale-force winds, and the yellow the radius of tropical
storm winds. The packet that contains that information also has information
about the true ranges and speeds in the report.
Some of the reports are predictions X hours in the future. So HANNA+24h is
the prediction for where HANNA will be in 24 hours and how strong it's
predicted to be.
It's not clear to me that Xastir displays all the information available in
the packet. I looked over some of the recent data using the perl APRS decoder
(ftp://ftp.eskimo.com/u/a/archer/aprs/Ian_Wade/aprsdecu.tar.gz)
and there seems to be a lot more there than Xastir is showing in the Station
Info dialog for the object. For example, I just grabbed this packet out of
my logs:
NHCTCM>APRS,qAS,WXSVR:;[EMAIL

which the perl aprs decoder shows as:
APRS Data Type= Object
Object Name= 'HANNA_ato' Object Status= Live
Day= 04 Time= 21 hours 00 mins UTC
Lat= 24 deg 30.00 min N Long= 73 deg 30.00 min W

Wind Direction= 315 deg Speed= 010 knots (11.5 mph 18.5 kph 5.1 m/s)
Tropical Storm: Sustained Wind Speed= 055 knots (63.3 mph 101.9 kph 28.3 m/
s)
Peak Wind Speed= 065 knots (74.8 mph 120.4 kph 33.4 m/s)
Central Pressure= 989 mbar/hP
Radius of Hurricane Winds= 0 nautical miles (0 miles 0 km)
Radius of Tropical Storm Winds= 275 nautical miles (316 miles 509 km)
Radius of Whole Gale Winds= 90 nautical miles (104 miles 167 km)
There could also be multi-point data hidden in the comment, but I'm not sure.
There's additional information here that I'm not sure is captured anywhere
in documentation I can find: for example, what's the overlay character
signify?
Gerry: do you know whether the data after the gale winds data is meant to
be a multipoint descriptor, and whether the overlay character is supposed to
mean anything in particular? The wxsvr.net web site appears to be gone for
good and the documentation that was once there is no longer available.

This has been the same ever since DoD turned off selective availability in 2000. There are times when it's better, times when it's worse, mostly due to satellite constellation geometry. If you use DGPS, RTK or WAAS, you should see an improvement of about (not precisely) an horder of magnitude. Lots of receivers have WAAS now. The simplest possible way to put it: DAO or Base91-Compressed packets allow for more precision but GPS, unless augmented, will not be accurate enough to make use of it. Unaugmented GPS _will_ fill in the extra digits but those extra digits will be worthless. This is a better situation than standard APRS or Mic-E packets where the precision of the packet is not enough to represent what standard GPS'es are capable of doing since Selective Availability was turned off years ago. Standard APRS or Mic-E packets give about 40' x 60' resolution in my part of the world. Use a WAAS unit and have a clear view of the southern sky so you get a good WAAS lock: You'll be able to take advantage of the extra precision that Base91-Compressed or DAO gives you. Assuming that the APRS software makes proper use of these types of packets. As soon as you lose your low-angle view of the southern sky due to obstructions you are back to 6 meter precision, so WAAS is useless in a lot of terrain. If you're in a fairly flat area with a good southern view then it can work while mobile/portable quite well. The datum of the GPS is also important if you're trying to actually use the extra precision: Set the GPS to WGS84 datum. DAO can send the datum along as well but Xastir doesn't currently have support for translating the received datum into WGS84 for display. We can also get into my old argument about actually using the extra precision with accurate maps and hand-placing objects (not using GPS), but that's a very specific case and not a common use. -- Gerry Creager -- [EMAIL PROTECTED] Texas Mesonet -- AATLT, Texas A&M University Cell: 979.229.5301 Office: 979.458.4020 FAX: 979.862.3983 Office: 1700 Research Parkway Ste 160, TAMU, College Station, TX 77843 ___ Xastir mailing list Xastir@xastir.org http://lists.xastir.org/cgi-bin/mailman/listinfo/xastir
Re: [Xastir] GPS Accuracy -- relative vs absolute
Actually, Curt and I worked through this some time ago. If you're not careful, you'll get me into the GPS Lecture Series mode. In bygone years on the APRS list, there were legions who groaned when that happened. In general terms, you've got GPS accuracy (repeatability vice a known, surveyed point) on the order of 6 meters. This has been the same ever since DoD turned off selective availability in 2000. There are times when it's better, times when it's worse, mostly due to satellite constellation geometry. If you use DGPS, RTK or WAAS, you should see an improvement of about (not precisely) an horder of magnitude. Lots of receivers have WAAS now. gc Jim Tolbert wrote: Running back to the desire for DAO packets. I am assuming that with standard APRS packets having 2 decimal places and DAO having 3 decimal places that I will be locating a particular GPS receiver to an area that is an order of magnitude more precise. I am probably not saying this correctly, but with the standard APRS packet, I have an area of uncertainty of about 20' x 40' ( in northern Wisconsin, US ( N45,W92)). By moving to a DAO packet, I will have an area of uncertainty of about 2' x 4'. If I have a bunch of GPS receivers of the same type, can I assume that the relative location is pretty good, even if the absolute location may be off a bit? I am really primarily interested in relative positioning. Since Xastir is really just plotting the data it receives, I am going to post this query on the APRS group as well, but I wanted to be sure to catch Gerry ...

I'm trying to figure out if it's worth the effort, given our relatively small numbers, to make things like VM images, TIGER shapefiles, DRGs, DOQQs, etc available via bit torrent. In the recent past I said I didn't know anything about torrent. That was somewhat false, as I've been using it for a few years but only in the "leecher" mode. When it got to "seeding" I always shut it down. Now I see a reason to leave it in seeding mode and have done so. I basically understand how torrent works and am getting used to some of the special lingo for it. I don't yet know if the below scheme would work but I'll put it out there. Someone more familiar with it can shoot it down: a) Someone runs a web page that has multiple ".torrent" files on it, representing all the things we have available to download. This could be a Wiki page, right? We'd have to be careful who has edit access to it (user/password). We have one such page now with three items on it, but it's not a Wiki. This web page ends up with very little usage as the bulk transfers happen client-to-client, not from this web page. b) People make various maps available for download. For instance I have three DVD's containing all of the USGS topos for WA that are freely distributable. I also have a good portion of OR and a few for ID/MT/HI. I'd love for these to be "out there" for other people to use. c) These same people create a torrent file out of this data, upload it to the Wiki, and edit the Wiki to make that torrent link show up. d) The first download ends up being a server/client relationship as you described, but if at least a few of the people doing the downloads leave their torrent client up and running, they become a shared resource for the same file. More than likely if we put maps up there we'll have non-Xastir people doing downloads as well, maybe even becoming additional resources to download from. e) The maps contributed in this manner must be freely distributable to preserve our good project name. Questions I have still: 1) Would we want to create a torrent for each file? For each CD or DVD set? In my case the DVD's were created from a LOT of CD's, and each CD had a LOT of maps on it. Of course each map is megabytes of data as well. I know I could create a torrent for an entire directory, but in the case of the DATA and METADATA directories for these CD's or especially DVD's the download would be huge. I guess once two people have it and are seeding it changes things, but that initial first download would take forever. 2) To make it easier on the map providers, one big download is the way to go. To make it easier on the "leechers" it might be better to have smaller increments. How does one decide this? I'm sure I could write a script that would make a torrent file out of each map file, but am not sure I could do the same to get the multiple thousands of torrents uploaded to a Wiki. 3) Is the idea of distributing maps via torrent workable at all? I've been looking for a method to make USGS DRG's and DOQQ's available for a number of years, and this seems the closest match to date. CAVEAT: I can't even START to think about this 'til I can extricate myself from a particular project, but what I'd like to see would be some variant on this...

Re: [Xastir] torrents and xastir
P2P excels when there's a lot of consumers, and you start with one server. If, however, each subscribers becomes a server (publisher) upon receipt, per-server bandwidth limitations, and system load, are mitigated. For some small value of convenience, too, a user can start a Torrent stream and come back to a whole file. When you're talking movies or songs... or TIGER datasets, this can be useful. We have some folks who don't have a lot of bandwidth, so a Torrent might be useful to them to retrieve stuff, but that's speculation. Overall, repositories in the conventional sense might be better/easier to maintain.

[Xastir] APRS Servers and verified connections
If any of you have been wondering why you've not been getting into the APRS-IS Core servers with reports, or weather, we made a change last weekend. In one of the poorest times I think I've ever picked for a server change, we changed all 3 Core servers to align with what the Tier2 folks decided to do several months ago: Require all connections be verified. I refer the interested student to the 'callpass' program for "How do I find a passcode" questions. The purpose? To push forward the separation of CWOP and APRS-IS traffic. CWOP now has its own servers and they're really doing nicely. APRS-IS has its own, comprising the Core and the Tier2 folks, and several others. Last January, as a consequence of Davis Instruments selling a bunch of weather stations, we saw a spike in Packets/sec on the APRS-IS servers (hosting CWOP), with poor performance, dropped connections and dropped packets and other server-overload problems.After a bit of analysis it became obvious that the frequency of updates, and the predisposition of weather to align themselves with other stations for observations every 5 min or so, was slamming our APRS-IS servers. We found some volunteers to run dedicated CWOP servers and stabilized the Core server situation after some potential problems, and started the painful process of getting CWOP members (non-hams, that is) to move over to the cwop.aprs.net rotation, and the Hams to connect to rotate.aprs.net as before FindU connects to all the APRS-IS Core and all the CWOP servers to gather its data. The backup FindU server does the same thing. There's a CWOP aggregation server that does the same thing, again. If anyone wants to see all weather stations on a map (think "Sea of Blue") they can point Xastir toward cwop.tamu.edu Port 30001 and see the stations pop up. Questions? Comments?

Re: [Xastir] Tiger 2007 shapefile issue...a beaut
Now decorrelate the GPGLL sentences from the 4-hr test by decimating to 30- or 60-second intervals. Decorrelation really does help. Average, then use a least-squares method to determine residual error. I don't use choke-rings or ground planes when doing kinematic work. We do make sure the antenna is aligned to N when we do it, though, as pattern will affect results. Finnegan's Finagiling Factor (also called "bias" in literature) has saved my butt a bunch of times in the field. I do a version of that in post-processing, too, but the whole procedure is best described in a journal article or over a beer. Or both.

SiRF mode has the longitude really messed up. I think I will hit up a couple of BM's and see how bad the data is. Maybe it may be recoverable by applying Finnegan's Fudge Factor. Trying to resolve a garbage can using just L1 and a consumer grade GPS will just give you garbage when you have only ddmm. to use. I went in knowing what the maximum resolution is: one count latitude = 0. meters; one count longitude = 0.1630 meters. I was willing to spot the rig +/- five counts moving so I would say that I made my self-imposed limit. I thought that it would be worse. Using a 2m range pole with a surgical sharp pick at the end will do your feet some damage. You probably have a outrageously overpriced choke ring antenna on top and that in itself is a real headknocker in its own right. I did a test with this setup here at home one day over four hours. I pulled out the NMEA $GPGLL sentences that were at PDOP= 0.6 and mapped them out. The resulting x-y graph presented an almost circular pattern of a diameter of 8 counts. Averaging the readings put the average right in the middle of the chart. I am quite happy with this mashup. Not professional grade but it will do the jobs that I need it to do. Have a good week.

Re: [Xastir] APRS-IS without authentication?
At this time, but changing in a week or so, the APRS-IS Core systems do not require authentication. Tier2 servers, for the most part have gone to requiring it. The Core is going to it. The reason the Core hasn't gone there so far is to allow "just a little more" transition time for the CWOP users, often less tech-savvy than hams, to learn they've gotta migrate to the new CWOP servers (running similar javAPRSsrvr code. gerry Tom Hayward wrote: On Mon, Jul 7, 2008 at 5:50 PM, Rick Green <[EMAIL PROTECTED]> wrote: 'authentacate' myself with my callsign and passcode.

Oh, yeah: I do have that. http://mesonet.tamu.edu/cgi-bin/pan?SERVICE=WMS&VERSION=1.1.1&REQUEST=getcapabilities is the getCapabilities document. Formation of the call would be similar to the WMS call for radar. Curt, shouldn't the same code support both? Also, if you ask nicely this WMS will give you both radar and the watches/warnings. FOR the record, warnings now are county-based rather than the old, familiar parallelograms. Warnings for Thunderstorm, Tornado, Flash Flood, and Special Marine are polygon-based (or Storm-based). gerry Eric Germann wrote: Colleagues, I spent some time last night beating my head on the wall trying to figure out why NWS Watch/Warning polygons weren't coming up when I zoomed way out to watch the storms a couple of states away. So I brought up their polygons via SHP files and couldn't see them. Of course, without a dbfawk file, they're black, so on my black background, they were missing. Problem solved there. But I still couldn't figure out why the "normal" watch warning polygons weren't coming up. Today they're up since we're getting hammered again in West Central Ohio. Then it dawned on me. They're coming via APRS-IS feeds and I have a 320km radius filter set. What I want to accomplish is to have nationwide watch warnings without polling NWS every couple of minutes. Seems like the way to do it is to create another link to my internal APRS server (which is linked to APRS-IS, so I don't have a bunch of clients polling the core) with a filter set to only catch the polygon announcements. Only issue is, I don't what the packets look like or how to build that filter. I'd like to keep the 320 km limit for stations which is a pretty good field of view on a 22" monitor. Any ideas, thoughts? Or would the better approach be to just use the NWS files for farther out and write up the dbfawk files (not an issue to do that). As an academic exercise, the multiline polygons would be interesting over APRS and filtering them. 73 de N1ICS Eric ___ Xastir mailing list Xastir@xastir.org http://lists.xastir.org/cgi-bin/mailman/listinfo/xastir -- Gerry Creager -- [EMAIL PROTECTED] Texas Mesonet -- AATLT, Texas A&M University Cell: 979.229.5301 Office: 979.458.4020 FAX: 979.862.3983 Office: 1700 Research Parkway Ste 160, TAMU, College Station, TX 77843 ___ Xastir mailing list Xastir@xastir.org http://lists.xastir.org/cgi-bin/mailman/listinfo/xastir

that .geo based on the range from the one you were working off of

some issues in the past with georegistration of their images. That is

Re: [Xastir] WMSRadar and net acquired .gif
I do the radar mosaic and something's definately off with that. I've been troubleshooting but I don't have an answer. I'll try a new approach tomorrow or Tuesday for this. Send me your appropriate RIDGE .geo for MAF. I'll compare it to what I have and see if we can get it better... Also: Why N0Z? I prefer N0R for base reflectivity (from a sorta professional view). Anyone want to work with me to make individual Level II sites available? I haven't time to script up the .geo's but can provide the data on site image dimensions... gerry Jim Morgan wrote: I need some help. I am new to Linux and Xastir both so please keep things simple for me. I noticed today that the radar that I load from the website www.srh.noaa.gov/ridge/RadarImg/NOZ/MAF_NOZ_0.gif is off by several miles. I am talking in the neighborhood of 50-75 miles. When I adjust the size of the .gif the center of the radar (the ground clutter) moves around as I change the size. I had the ground clutter centered but the edge of a recent storm was real far off. So I tried the WMSRadar on my Xastir and discovered that the image is indeed better but it shows the storms about 120 miles north of their actual location. What setting(s) do I have wrong? The purpose of this set-up is to serve as a remote station for Skywarn operations if something happens at the NWS so I need the radar to be as accurate as possible. Oh the technical stuff-- Ubuntu 6.06 and Xastir 1.71. I am not much of a programmer so this is all real close to OEM specs.

Re: [Xastir] does CWOP filter get new DW stations?
One thing we're looking to reduce/eliminate is the "Sea Of Blue effect
when folks start putting all CWOP data back out on RF. javAPRSSrvr has
modified over time to do that. CWOP non-hams are not validated
connections and thus shouldn't go out save when we're looking at
compelling need: emergencies like chemical release, severe weather, etc.
Using cwop.tamu.edu as an aggregator of all three CWOP servers allows
this.
A second instance of javaAPRSSrvr is pretty straightforward. That'd be
my recommendation but pose this to Pete on the javAPRSSrvr list and see
what he recommends.

ok, feeling dumber yet answering my own question.
Is the logical answer to deploy a second instance of the APRS server SW
here, take the firehose from CWOP's servers, then allow the internal
clients to filter it to the region of interest? Running it on linux, a
second instance running on the same box shouldn't be an issue should it?
You can definitely tell the CWOP feed on the Xastir status line. It's
the one with the red arrow lit all the time :) Sure makes the station
names zing by also on the status line.

Here's sort of a (dumb) question:
I use javaAPRSSrvr locally to aggregate all my APRS traffic from a
144.390 digi, a weather digi and two Telpac's for Winlink, as well as
Xastir. This server then establishes ONE bidirectional connection to
the *.aprs.net servers. If I wanted to bring in a feed from the CWOP
servers, how do I configure a readonly simultaneous upstream to go
along with the aprs ones? Basically, I want to aggregate it in the
local instance, so I can filter, db it, etc, but NOT gate CWOP servers
back to APRS-IS?
Thoughts?

Please consider connecting to cwop.tamu.eduport 30001 for gathering

There are 3 CWOP-dedicated servers. These are for the CW/DW
stations. Hams should continue to use the APRS-IS servers _unless_
you don't want your data pointed to RF.

Re: [Xastir] Xastir and Fedora
Eric, Thanks. Several issues have appeared. Aprsd can be misconfigured to cause looping in the APRS-IS, and often is. The javaAPRSSrvr code has been revamped to detect and solve this but we still see hiccups occasionally. Xastir makes a better iGate, and if hams ask AE5PL, they can get the java code for igating or 2ndary servers. I'd much rather see a script to take the java package and make it go into a predetermined area. I'd also love to see it executed as a non-priv user with access to the needed ports/sockets. 73 gerry Eric H Christensen wrote: Gerry, Just got finished talking with the lead of the Amateur Radio SIG.

One thing to consider when doing this work now is that several Warnings are now presented as polygon objects instead of Counties (at least officially; the software updates are not rolled out yet to stop warning whole counties, but the intent now is to _not_ warn whole counties). See http://www.weather.gov/sbwarnings/ for more info on SBWs. The intent is to reduce the warned area to more sharply focus on an area of maximal potential for storm damage rather than warning a whole county when only, say, one corner is at risk.

Re: [Xastir] What county am I in?
Specifically, what I've been asked for is the ability to query some sort
of database or server with GPS coordinates and produce both Maidenhead
and County Name. Both are easy to do with PostGIS, and I'm probably
going to write a SOAP service and a web page that'll do it.

Re: [Xastir] GPS question, off topic.
Couple of minor points, although Lance's pretty well on-track. Lance Cotton wrote: John Ronan wrote: Assuming that WAAS signals are quite strong, what would the advantage be between a Phoenix 200 Smart Antenna http://www.ravenprecision.com/ca/Products/description.jsp?partNum=117-0171-071&Category=1&Type=1 over a garmin GPS-18. It's for an agricultural guidance solution they are the two GPS options available. I suggested to him to borrow my GPS-18 (which I use with my OpenTracker 2) to test it before deciding on which to use, as I know WAAS signals are quite strong here. What would the GPS be used for? APRS Tracking? Farming? The Phoenix GPS claims sub-meter accuracy. Barring marketing lies, this is not possible with only WAAS. WAAS would likely get you to 3 meter accuracy at best (Gerry N5JXS certainly knows more about this). The Phoenix also claims to use a helical antenna. There's little benefit of a quadrifilar helix over a dielectric patch antenna for low-angle satellites, and low angle satellites tend to detract from accurate positioning because of the interplay of more atmospheric traversal than higher-elevation constellation selection. I think they're letting marketing invade technical space here. The eDif feature mentioned for th Phoenix appears to attempt to model ionosphere delays by analyzing multiple satellite signals over time. Normally ionospheric delay (signal bending) correction is done using a 2nd GPS frequency, on which the actual data is encrypted, but the clock information can be extracted. This 2nd frequency is what is normally referred to as "Military grade" GPS. The eDif claims to be able to get the same type of correction data out of a single frequency receiver. It also sounds like a costly add-on. Aside from the fact that I've got and use dual-frequency receivers and have no current connections to the military other than having being married to a retired Army Nurse, dual-frequency is usually expensive to obtain. Relatively few are purchased compared to Garmin and other OEM and consumer units, so there's no economy of scale. Although I've theorized about how to determine iono and tropo delays over the years using single-frequency techniques, it's virtually always required two or more receivers to make the theory work, over known baselines. The other differential positioning technologies mentioned are likely DGPS, where you have a separate GPS receiver at a precisely known position which radios out the offsets (within some "local" radius) between the GPS-derived position and its precisely known position. DGPS receivers recieve and incorporate these offsets into their calculations. Some experiments concerning "local radius" conducted here several years ago suggest that said radius was a tool designed by Trimble to sell more DGPS base stations... or more precisely, that "local radius" was pretty general, and on the order of hundreds to thousands of kilometers. The question back to you, I guess, would be: do your friend need sub-meter accuracy and 10Hz position updates? (Most NMEA-out GPSs output positions only at 1Hz or less, depending on the NMEA sentences enabled.) A lot of precision agriculture applications do need meter or better accuracies, especially if the GPS is driving the tractor. I'm not sure the Phoenix is the right answer for this, though, unless I got more information and had the opportunity to play with a pair of them for evaluation. gerry -- Gerry Creager -- [EMAIL PROTECTED] Texas Mesonet -- AATLT, Texas A&M University Cell: 979.229.5301 Office: 979.458.4020 FAX: 979.862.3983 Office: 1700 Research Parkway Ste 160, TAMU, College Station, TX 77843 ___ Xastir mailing list Xastir@xastir.org http://lists.xastir.org/cgi-bin/mailman/listinfo/xastir
Re: [Xastir] online radar
All, problems abound here with hardware dropping like flies.

In the midst of all this, radar processing fell over because of a system change we anticipated... someone failed to tell me they were ready to take the system offline. As soon as I can, I'll have radar working again on another system, likely sometime today. In the mean time, I have to keep up with the day job.
