Reading over this page http://www.swcp.com/~russo/shape_web/tutorial.htmland it appears that there are a lot of options you can configure, but a little of this was over my head at this point. Well, it so happens that there are already some dbfawk files for the TIGER shapefiles written and in place in the standard xastir distribution, so you don't really have to start from scratch the way Tom's tutorials walk you through. You can find them in /usr/local/ share/xastir/config/tgr*.dbfawk (assuming you installed in /usr/ local/). Use the info on Tom's web site to figure out how to tweak the dbfawk files to behave more like you want. So now that I have some data, I would like to make it look like the original tiger data and dont really know where to begin? Begin by asking _why_ you want it to look like the original TIGER data. (: By "original TIGER data" I assume you mean the TIGER data as rendered by the TIGER server. The short answer is that it'd be tough. A longer and more useful answer is to look in the dbfawks mentioned earlier and start modifying. You can probably eventually get there. You can also affect how your maps look by changing the background color and the map labels fonts (map -> configure). What are all those different files for and how can I start editing this to my liking? The files you mention are the actual data. You generally want to change how that data is rendered (via dbfawks, map properties, and tactics) and not actually change the data. I also have MapInfo data available to me as well as Precision Mapping and Street Atlas, as Darryl mentioned it would be useful if we could somehow use that data as well if xastir supports it? Talk to the vendors about that. Mapping programs are generally somewhere between extremely unhelpful and hostile about use of their data by some other software. There is an APRS application called APRS+SA that's some sort of plugin type app for a very old version of SA (v9, IIRC). Unfortunately it was recommended to our balloonsat project and I have found it to be so frustrating and complex that it is useless. I have been actively campaigning to replace it with xastir (or anything else!) since the first time I used it. APRS+SA convinced me to use a dedicated app like xastir. I have to say this is the most I have ever used xastir and it is the most advanced APRS program I have ever used.

There are some advantages to forum-based support rather than mailing-list based support. With a mailing list, you have to get yourself subscribed, hope your provider's anti-spam measures don't treat the mailing list as spam, post your question, and deal with whatever noise there is on the list until you get your answer (if you get a good answer - not usually a problem on ths list, but I know of plenty other "support" lists where 75% of the requests for help are ignored). Not to mention poorly configured lists that send replies in private rather than the list *grins* With most web forum software, you can easily set it to notify you of responses to your inquiry, and never go back there until someone responds to your inquiry.

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.

This may seem like a vague question, but as I don't know I feel compelled to ask :) I want the best quality maps that I can get to use with Xastir. The tiger maps are great, and while the map caching feature is helpful, still takes longer than I'd like it to display. I have read the maps entry on the wiki, but I know nothing about the various map technologies. My end goal would be to download the best quality map data I can get my hands on and cache it locally on a server. Space is not too much of a concern, I have plenty of storage options available.

[Xastir] Compressed objects creep a little after creation?
Hi, I just noticed that some compressed objects tend to creep a little in location after being created in Xastir. Here's an example: I created a non-moving compressed object (I left speed/course/altitude fields blank) with a location of N 60 12.011, E 024 56.171. The first location field of an APRS object that Xastir sent was '0&i#TiQK', which converted back to readable form is about N 60 12.01115 and E 024 56.17185. The second time that object is sent, the location field is '0&i#TiQH', notice the change in the last character. The longitude in this packet is about E 024 56.17091. And then the third time includes a location field of '0&i#TiQE', a longitude of E 024 56.16996. All packets sent after the third one until the object was killed contained the same location as the third packet, '0&i#TiQE'. All of the kill packets also had '0&i#TiQE' as the location. In practice this creep is just barely noticeable if you zoom to level 1. Converted to distance, the difference between the first and third packet is about 2 meters. Without looking at the code, I have a theory of a sequence of events (hmm, I'm sounding like the narrator in Seconds from Disaster tv-series..) that might exaplain this: 1) Xastir takes my input coordinates, converts them into Xastir's internal representation and then to compressed format, and sends the object. 2) Xastir sees the APRS packet it just sent and converts the compressed position into Xastir's representation of the location -> a slight change can take place here. 3) When the time comes to resend an object, Xastir converts the internal format location got from 2) above to compressed format again, moving the object a little again. 4) goto 2), until the location settles into a value that doesn't cause a step change when converting between Xastir's internal format and APRS compressed format location. I'm running CVS Xastir (1.8.5), compiled on November 4th. Tapio ___ Xastir mailing list Xastir@xastir.org http://lists.xastir.org/cgi-bin/mailman/listinfo/xastir

James Jefferson had one on his site that was around 2MB I think. He added a missing continent to it a while back (Antarctica) but the original data I think came from somewhere else. That one might work fine, but then there are two (somewhat minor) problems to consider: *) Xastir would need to be always compiled with Shapelib support in order to use it. *) The "development" and "stable" releases would need to add this so that people always had the base map, or else we could add it as a separate download on the File Download section of SourceForge to keep the source downloads small, and just put the map into any compiled binary distributions. Because of the Shapelib problem, I'd prefer to have something in Dos/Win/PocketAPRS format, so that any lack of libraries won't affect it. Then again, we can do so much more with Shapefiles and that's one of my favorite formats! I've thought before of including Shapelib sources with Xastir itself so that it's always available.
