The above path.  Looking at mine here the map-cache directory hasn't
been used for a while.  Probably  because OSM maps get cached in a
new place and I've been using OSM maps for a few months.

[Xastir] Possible bug in Open Street Map support

[David Flood]

The flush map cache code may need to be updated to remove downloaded Open
SM's...

I had OSM support enabled for awhile but then turned it off...when I zoomed
back out to that setting it used the cached map.  And I couldn't get that
map flushed at any zoom level until I exited and deleted the .gif and index
in the cache directory.

[Xastir] Maps!!!

[Ryan Collier]

Good Evening,

Want to start off with a congrats on a great program.

Now to what I am having a problem with:

1.) The program is saving the maps but I can not get the program to find
the cache map files. The cache map files are being saved here...
/home/user/.xastir/map_cache

2.) Everytime it down loads I get these on the screen.
DB -get: method not permitted before handle's open method
and
DB -put: method not permitted before handle's open method

3.) I downloaded the shape files but the weather map will not show up on
the openstreetmap?

I am guessing I am doing something wrong or forgetting something.

As far as copying the tile cache from one machine to another goes, then
I think there is also a database involved, but I don't know enough about
how that is used to know if it would be simply a case of copying the

Because it violates the terms of service for many (most?) map servers. Which

Thanks for the info guys.  I guessed it would be IO bound (mostly on the
initial database read), but I don't know how complex the rendering
operation is.

If you had plenty of RAM you might squeeze some improvements out of the
system by using a ramdisk for the mod_tile/renderd cache storage just to
see the same tile from hitting the disk multiple times during
render/apache/xastir steps.

Since xastir is already smart enough to cache it would be awesome if xastir
could hit mapnik directly.

[Xastir] OSM tile handling improvements

[Jerry Dunmire]

I just committed changes to CVS to improve the OSM tile download and
cache. These are effective only if libcurl support is enabled:

 - check for tile updates for tiles that have been cached for more
than 7 days (per OSM tile usage policy).
 - use http pipelining (may not help much, since it appears that OSM
servers do not support pipelining for tile downloads.)
 - new debug level, 8192, for verbose output from libcurl

[Xastir] Online open maps downloading too frequently

[Alex Carver]

I just noticed my copy of Xastir is attempting to download the OSM tiles about 
once per minute or faster.  I looked around the .geo file and in the timings 
dialog but there's nothing controlling the download rate of the tiles.

The reason I ask is because Xastir consumes 100% CPU and pretty much blocks 
everything until the download/cache check is done.

Is the rate hardcoded or is there a soft config setting somewhere that I 
overlooked?

That link works.  So is your issue the strange characters and the

Re: [Xastir] Maps won't cache

collision of the h...@seanet.com flavor, containing:
 This smells to me (without looking at the code) like a tile cache size limit 
 problem. I don't know what xastir used to decide how much map data to cache, 
 but that's the setting I would hunt for. 

There is no such setting for OSM map tiles.

In fact, in browsing the code the only place I see that would remove OSM tiles
from the OSMtiles directory does so when the tile is bad.

I'm going to have to fire up Xastir on my laptop (which runs Ubuntu) and see
if I can reproduce Skyler's issue.  I only use Xastir on that laptop for
search and rescue, when I never have internet -- and so I never use online
maps there (I use shapefiles and topo maps in that activity).  It will be
a day or so before I can try that.

 Another idea would be to generate data in advance. I just poked around in 
 mailing list from late 2012 and saw some talk about using Mbtiles data with 
 xastir. Mbtiles is a format for mass offline storage of raster tiles. It's 
 supported by GDAL, and I think that means it works in xastir? You could use a 
 program like Tilemill to generate full Mbtiles coverage for the areas you 
 need. Side benefit (if it works): you can distribute the same Mbtiles file to 
 all of your volunteers, minimizing training load. 

Xastir does *NOT* actually support gdal raster formats, which is why we are 
quick to point out that most uses won't want to bother with GDAL.  There was 
brief bit of development effort in that direction about 10 years ago, but it 
resulted only in the support of OGR vector layers, not GDAL raster layers.  But
the OGR code is akin to the older shapefile code without dbfawk --- meaning
that Xastir will only render certain types of ogr data layer nicely, and all
others will just render as ugly black lines.

Re: [Xastir] Script to cache some maps

[Kurt]

The bottom line is being able to store some sort of map data on one's box so 
they can go portable without any internet link whatsoever.
This is what I am talking about:  http://download.geofabrik.de/
One can cue up whatever they want.  YAAC can process and store the data locally 
for offline use: YAAC - Yet Another APRS Client
The Tiger maps from '06 and the Cloudmade '08 maps were dropins forXastir in 
the past but not longer available.
YAAC's ok but I still like features in Xastir.  It is rock steady once 
configured.

Sort of not exactly.  The online map code is different from the offline map
code in that the georeferencing data seems to be stored in the map cache
database.

Looks like I played with this about 3 years ago.  From the remnants it
seems i had hacked out a script to download OSM tiles and another to
generate the corresponding .geo file that xastir needs to use it as an
offline map.  I don't recall how well it worked out.  As I said earlier, I
abandoned the project because of the disk space requirements.

Surely the ultimate solution is to download vector data and have a
well-written dbfawk which shows the elements you are most interested in?

Vector data takes up much less space than tiles, and setting up a tile
server is not actually straightforward (plus, you have to download the
vector data to make your own tiles anyway).

I run OSMAnd on my phone.  It uses vector data and renders it on the fly,
so all my mapping (and routing) for the whole country is done locally (no
network needed).

[Xastir] tamu down Tiger2006SE alternatives?

[Kurt Savegnago]

Hi,

  Been using Xastir for a couple of years now and just was finally able to 
track down this list thank heavens.  The 2006 TigerSE maps compiled for Xastir 
were so doggoned easy to install.  Is the method for installing the 2008 
version on the wiki the way to go now for installing maps?  I've done searches 
online and through the archive here and just found that there was mention that 
all the weather maps servers are gone now.

  Is it possible to cache the online Tiger maps for use offline or is that not 
possible?

Hi Everybody

Is something going with Xastir?
I fiddled around with it and got upgraded to 1.9.9 but my
Online/OpenStreetMaps.osm doesn't open.

So I think I did everything right but I am unsure, I have had Linux for 
only a few years.

I have Ubuntu 10.04 on a Dell Dimension 4700 it is dual boot with Windows XP

I did look a bit and found where there was a map cache at and 
OpenStreetMaps were put

but now they don't come up.

Which maps?  The OSM map tiles are saved in ~/.xastir/OSMtiles/

Others can be cached in the directory you mention.  I mostly use OSM maps these days.  
Much quicker, very much up-to-date.  Entirely different caching code used in Xastir.  I 
don't know why it would be caching maps but not retrieving them.  You do have to match 
the same zoom level and map center if you expect to get a cache hit.  If you're 
constantly zooming/panning, you're not going to get many cache hits unless you use the 
OSM tiles.  If you use OSM, remember the F4 key as it will force you to zoom 
levels that look best with those maps.  Immediately after I zoom in or out I hit F4 if 
I'm using OSM maps.



2.) Everytime it down loads I get these on the screen.

DB -put: method not permitted before handle's open method


Are you using an RPM-based system?  If so you might try this:

rpm -qa | grep libdb

Mine shows this:

$ rpm -qa | grep libdb
libdb-4_5-4.5.20-113.1.2.i586
libdb-4_8-devel-4.8.30-11.1.4.i586

libdbusmenu-qt2-0.9.0-2.1.2.i586
libdb-4_8-4.8.30-11.1.4.i586

The important thing to notice is that the -devel package version number 
matches the installed libdb version number.  I'm running OpenSuSE-12.1 64-bit, fresh 
install here, but it looks like I might want to remove some 4.5 packages so they don't 
conflict with the 4.8 packages, if I can (sometimes other packages depend on them and I 
can't remove the library, but I should be able to remove the 4.5 -devel package).  It's 
when you cross version numbers between the -devel and the library that you most often run 
into issues.  If I remember correctly, if you only have one -devel package installed for 
libdb and it matches the most recent libdb package, you're probably ok.



3.) I downloaded the shape files but the weather map will not show up on
the openstreetmap?


How did you download the shapefiles?  Using the script as root?  What version 
of Xastir are you running, and did you install it from sources or from a 
pre-compiled package?  We just tweaked the script a couple of weeks ago to 
download the latest weather Shapefiles, but that version is only in CVS.  You'd 
probably need the latest dbfawk files from CVS to match as well.

[Xastir] Maps OSM

[Dave H]

I'm lucky to still have a pc running (mainly Inet but sometimes RF) Xastir
with local OSM maps - is there a procedure I can follow to transfer the
whole map cache over from the one pc to the new one?

I tried just scp'ing  from the map_cache directory over - which failed on a
database error - Should I scp over the whole directory tree at .xastir  ?

I'm in the UK and without maps I find it hard to get people to take it up -
they say their uiview maps are crud but  worldoutline is not a step up.

Re: [Xastir] Script to cache some maps

[Skyler F]

Well since nobody has a script that I can get to work, and I don't know too
much how to code, I am going to make a basic script which simulates the
arrow keys, and has a delay given by the user to Cache my maps. Crude, but
better than doing it by hand.

I don't see why nobody just puts together an easy script, or even builds it
in xastir to Download (not store it on the cache) the tile maps. If you are
worried about server stress, I am sure I have stressed the servers more
times than if I could have just downloaded it once, because each new
device/ xastir install I have to do the same thing.

I don't really get what maps I am supposed to use other than tile maps, it
is time consuming, and never really works right when I try to convert the
shape files from OSM, and tile maps are pretty much what everybody wants to
see in the 21st century.

[Xastir] Intro and question

[David Giddy]

Hi,

I've just joined the list as I've started using xastir in a mobile APRS
setup here in VK.

My immediate question is around map caching. I'm currently using OSM Cycle
map as it seems to be the only one to easily use here in VK. My question is
how I can pre-load the map cache with all the tiles for an area of interest
so that I can continue to use it offline?

I looked through the xastir wiki and couldn't find anything on this, so
hoping someone on this list can point me in the right direction.

Looks like the mod_tile folks already thought of that: use memcached support 
built in, assuming you've got the RAM. 

And maybe turn _off_ xastir's caching, otherwise you're paying double for

Re: [Xastir] Possible bug in Open Street Map support

[Jerry Dunmire]

Thanks for the report. Yes, there is a problem with the transition
from linear scaling to
OSM levels when OSM maps are first selected and when they are
deselected. It causes
locations to be off (see the reports above related to being in the
ocean) and constrains
scaling to the OSM levels when they shouldn't be.

The other confusion is that the scale set through the GUI is for the Y
axis, but the OSM levels
are for the X axis (latitude). That shows up as a difference between
the scale value entered
and the actual scale value used and displayed, because I have to
rescale the Y-axis after
binning the X axis into the OSM levels.

I am working on this issue, and ask for your patience. Please consider
the OSM support as alpha at best!

Thanks to everyone for  the positive feedback and useful suggestions.

Ideally you should get cache hits if you use Bookmarks and then
stick to Pan/Zoom keys (assuming you did that while online to
populate the cache).  That's how it works for other online services.

I don't know if it works the same for OSM.

As another backup:  You can use the screenshot capability in Xastir
to capture images you like.  Xastir creates an image file and a .geo
file that goes with it.  Copy/rename each set to your map area and
you'll have a set of images you can play with from then on.  It
takes a while to do this for a large area for all the pans/zooms
you're interested in, but for a small area it's workable.

 Yes, but if you're using OSM maps they should get drawn out
 of the cache instead of snagged from the 'net each time.

Should being the operative word.  I think it's going out to check for more 
recent tiles if they're on the server but it does do a download and then pulls 
from cache (the status bar says Downloading tiles... for a while).  It mostly 
hangs on that downloading step and then moves on as soon as it's done.

It's a little disappointing because I can't have the radar images going with 
the OSM otherwise my windows are going to hang on every refresh.  I'm living 
without the radar for now.  Assuming I have a spare tuit available somewhere 
(round or square, maybe even triangular) I might have to dig and see if I can 
prevent the download ahead of time for any tiles that exist.

 
 Glad you figured out the problem!

GDAL to Xastir.  Xastir does *nothing* with GDAL for rasters, and has very,
very limited support for vector data through the OGR library (part of GDAL)

There was a plan to make Xastir use GDAL for rasters, but it never got finished.

You can link gdal to Xastir by following the instructions.  But it buys you

Re: [Xastir] Script to cache some maps

[Kurt]

I've never had map caching work.  As soon as I was offline, I get nothing.  I 
have some of the old 2006 Tiger maps and the 2008 OSM maps from before those 
servers went off line.  The biggest handicap is a source of maps that can be 
used off line for Xastir without having to do a bunch of legerdemain to get 
them to work.

Yes, I know it is bad to download a lot of tile maps, and that is not my
intention, just need a certain area for different APRS events.

I am getting sick of going over the whole course in every zoom level I want
every time I want to use APRS offline. I then have to double check offline
to make sure I didn't miss areas.

Has anybody wrote a script or can point me in the right direction to making
a script? The problem I have with simulating arrow key presses is that I
can't predict how long the maps will take to load.

Re: [Xastir] Script to cache some maps

[Kurt]

One comment here is that OSM map tiles can be downloaded in one form or 
another.I downloaded 11Gb of north american data osm.bz2 over a high speed link 
over the weekendin a few hours from Geofabrik.  If one doesn't wish to burden 
the tile servers howabout a way to deal with the bulk data that is available 
for use?It gives a decent mapset in YAAC and if they didn't want people to use 
it, theywouldn't make it available in such large chunks.  
Now I understand, downloading in bulk from a dedicated server is different than 
usinga tile server but there must be a way around this so all stay happy.
It would be nice to have some means to have a reasonably current cacheable 
mapsetfor use on Xastir when an Internet connection can't be had.

IIRC it is OSM vector data for some or all of the united states.

My stash of vector data is 100k and/or 24k topo data, National Atlas data,
and about 10 states worth of the old TIGER shapefiles, and it totals about
12Gb.

Well, if we're talking about a hypothetical online tile cache for xastir
users, yes.  _you_ want Silicon Valley.  _I_ want Alabama, north Georgia,
middle and eastern Tennessee, and the Florida panhandle.  Basically
everyone wants their home turf in full detail so we're effectively talking
about the whole US.

I don't recall details on how big the tiles are, but when tile servers
first came online I set up a 50Gb VM and started caching at all zoom
levels.  It became clear it was impractical.

Sort of not exactly.  The online map code is different from the offline map
code in that the georeferencing data seems to be stored in the map cache
database.

Looks like I played with this about 3 years ago.  From the remnants it
seems i had hacked out a script to download OSM tiles and another to
generate the corresponding .geo file that xastir needs to use it as an
offline map.  I don't recall how well it worked out.  As I said earlier, I
abandoned the project because of the disk space requirements.

Re: [Xastir] Script to cache some maps

[Andrew Errington]

Surely the ultimate solution is to download vector data and have a
well-written dbfawk which shows the elements you are most interested in?

Vector data takes up much less space than tiles, and setting up a tile
server is not actually straightforward (plus, you have to download the
vector data to make your own tiles anyway).

I run OSMAnd on my phone.  It uses vector data and renders it on the fly,
so all my mapping (and routing) for the whole country is done locally (no
network needed).

So the ultimate solution for the raspberry pi folks would be to run a tile
server on their home computer (so there is no violation of terms and you
can download as many tiles as needed), and then run this script to cache as
many maps as needed onto their pi. I think that is the way to go!

Heck, you could probably even set it up so every time the pi connects to
your home network (back from your trip when you used the maps), it
automatically downloads the latest maps from your home tile server.


I'm sure with time, there might be some hams with acces to big data centers
and might be willing to serve a OSM server for hams.

Re: [Xastir] New Online Maps in Git (Canada & U.S.)

[Curt Mills]

Yea, these new maps are only available at certain zoom levels. If you want
to be smart about it you can go into map properties for each one and set
zoom levels at which they will activate. Using that method you can also
have Xastir auto-switch to different map sources at different zoom levels.
If you do that then you select multiple map sets in Map Chooser. The trick
is to make only one type of raster map activate at a time, else you'll end
up loading one raster on top of another, which is counter-productive.

You can also load vector maps on top of raster maps. In that case you can
load unlimited vector maps on top of one raster and see them all, assuming
none of the vector maps have areas that fill. If that's the case then you
have to select which layer each loads at to create the map stackup you want.

No significance to the black vs. grey except that they probably send us a
small tile that says "error" or something, and that's the background color
for that tile.

The not found in cache message is because a local cache was added quite a
while back to speed up drawing if you're not moving around much, or if you
stick to certain centers/zoom levels and the arrow keys for moving around.
In that case you can eventually get the cache loaded with what you
regularly use and not have to fetch from the 'net' much. Not sure whether
we should change the messages: I find it useful to know that I didn't get a
cache hit and that it will take longer to load.

I don't think there's any way for Xastir to know enough about the remote
server to be able to display messages like "not available at this zoom".
The remote server can change at any time, so if we hard-coded these in,
we'd be wrong half the time. Better to leave it generic. You'll get to know
the map sources the more you use them.

 The OSM code is really just a (simple) modification of the tigermaps
 code. The slow speed seems to be all related to pulling images from
 the server. It doesn't appear to me like the images in the cache get
 re-used if the center point changes. So even minor location changes
 can cause a new map to be pulled. A far better solution would be to
 cache OSM tiles (256x256), ala web based maps, but it I opted for the
 quick fix first...

It would be good to cache the map tiles on the local hard drive.

Lynn pulls the tiles, and caches them for use on the WinCE mobile
devices. I think he stores them for 7 days, or to a maximum amount of
space used. The user can over ride these values as desired. I have
caching set to never discard, as I want to use the large hard drive on
my laptop for offline use. I don't have a mobile data connection, so
it makes more sense for me to grab the tiles and keep them on my
drive. For limited resources like the Win Mobile devices, it's better
to dump old tiles, and download new ones as needed.

Speaking of this, when storing the tiles locally, one should keep in
mind the folder naming convention. I currently have my OSM tiles being
shared by RadioMobile, and APRSISCE/32. There's no need to have
multiple copies of the same tiles. If Xastir saves the tiles in the
same manner, then there's another shared resource available. Obviously
the programs being mentioned run on different platforms, but keeping
the same tree structure means that cross platform compatibility is
already in place if/when the programs merge or cross to the other
platform. I'm pretty sure that RadioMobile works under Wine, so the
need is probably already there.

Another thing that Lynn does that is interesting, is that he varies
the opacity of the OSM map in the background. I prefer my background
map to be as bold as possible, but Lynn likes his vary washed out.

Here are a couple screenshots that Lynn made of tracking a balloon
flight earlier today.

http://ldeffenb.dnsalias.net.nyud.net/Tracking/Balloons/WB9SKY-11-2010-06-09%20Burst2.png
http://ldeffenb.dnsalias.net.nyud.net/Tracking/Balloons/WB9SKY-11-2010-06-09%20Falling.png

You can see that the map in the background is very light. This makes
the user data POP right out at you. Looking at Tom's map of
Albequerque that he posted earlier brought this to mind. I had a hard
time seeing the APRS stations on the map, as everything was jumbled
together.

Perhaps varying the opacity of the map images is an idea that Xastir
can do as well. It is a handy feature.

[Xastir] Quick Ques.: OSM Maps from cache?

[Kurt Savegnago]

Hi,

  Been using Xastir a long time and getting ready to go into the field without 
internet to track R/C models and amateur rockets. I took the easy
way with the canned maps from ftp://aprs.tamu.edu/pub/.  Just unzip and go.
  Yeah I know, from 2006 but for tracking models or as a base map for watching 
what's going on in the area are not too bad. I had a tough time with the 
readmes and whathaveyous to put other maps in, other than the online stuff 
generally worked well going out of the gate.

Re: [Xastir] Quick Ques.: OSM Maps from cache?

[Jerry Dunmire]

Hi Kurt,
Which of the OSM maps are you trying to use? The full size maps
probably won't work due to floating point to integer transformations
that yield new center coordinates for the center of the map for even
the most minor changes. However, the tiled OSM maps should (and for me
do) work great off line. Simply view the areas you need while
connected to the network and then the tiles are cached.

I'm sorry this information is late (I was on vacation and away from
computers), but if you are still interested and need assistance, let
me know.

Re: [Xastir] map chooser for idiots

[MJ Inabnit]

I was hoping for something more automagic.

What is the least painful here--using OSM or buying some kind of disc?

I would like to populate maps into cache so the program can just grab 
the map from the drive and not be connected to internet once I get the maps.


Seems like there should be an easy way for this in this day and age (not 
grumping, just sayin')


Even if I close the program and re-open it, the program stalls for many 
minutes, even though, if I understand it, it should already have the map 
in the cache.


I am stumped.

Greetings all:

I've been poking around howto/wiki/readme/archives etc trying to figure out a very

So far, the server times out, and mm.aprs.net doesn't resolve (from running 
xastir from terminal window).  This basically makes xastir stupid and it fails 
to function at all.  I kill it and remove the .config and start from scratch, 
but there must be a better way..

I really am an idiot when it comes to this stuff.  The chooser is extremely 
ambiguous and I fail to infer what any given title might render.  What I hope 
to do is make a very basic how-to for Mint LTS versions of xastir and 
soundmodem.  I'm using Kamal's updated ham software PPA repository for these 
binaries.  So far, I've had tons of fun and have built my first loaner laptop 
which is now in a remote area of Humboldt county California.  I'm building the 
next loaner laptop now, but after seeing the map failure with my first laptop 
once it was out of reach of the internet and cached maps completely failed to 
render, I want to make sure I get this one correct. .. :)

What would be perfect is something that will look like google maps that show up 
when I go to aprs.fi.

I've spent several days digesting info found on the net, but I seem to still be

It looks like creating a tile server might be the way to go if one has

Who has experience with this, and can point me in the right direction for

Re: [Xastir] Script to cache some maps

[Fred Hillhouse Jr]

I run Windows and use APRSIS32 and I use more than the OSM tiles (e.g.,
ArcGIS Topo).

I have used an USB hard drive for tile storage while mobile. You can get
really big ones for lower cost these days. Some might argue an SSD makes
more since. I am leery of that since I have had several USB Flash Drive,
plus, they are costly.

If you are rendering your own tiles, then plug in a portable hard drive and
copy (backup) the latest tile revisions to the portable hard drive.

Most of the time, space is not all that important. I have less than 10GB of
tiles and I do look around the world when something interesting is
happening. I am in between projects looking to roll out my newest
configuration.

I wrote an application to download the tiles I need. I started first with
something that simply used a GPX file as the source. I haven't finished a
routine to fetch tiles within a polygon. That would be useful for counties,
cities, etc. A whole state would be extreme.

I don't know if Xastir can actually use tiles but it seems like a logical
extension if not.

Best regards,
Fred N7FMH

This sorta sounds like the worst of both worlds to me - you are still tied
to your home network connectivity to get maps, but you additionally have
all of the hassles of running a server just to keep maps available.  ugh.

I'm with Andrew, my "ultimate" is vector data that xastir can ingest
directly.

The only reason for me to set up a map server is if I can't get said vector
data formatted for xastir.  There's a slight advantage to sourcing OSM
data, since that's the FOSS GIS data du jour.  A portable tile server (e.g.
mobile, incident command post, remote event HQ, etc) would likely require a
fairly well endowed computer (high end laptop, potent SBC like an Intel
NUC, or _maybe_ a higher end ARM like a Jetson TK1).  I seriously doubt
Pi/beaglebone/etc is going to get the job done as a tile server, they're
just too anemic computationally.

Is the tiling system with the zoom/x/y.png standard for non OSM like the ArcGIS

Does this system work cross between maps, ex. Does 5/5/5.png have the same lat

Re: [Xastir] Script to cache some maps

[Fred Hillhouse Jr]

If sitting under a tent (or in a Jeep) somewhere doing APRS, using vector
data is faster than loading a few tiles? And, does the speed matter that
much?

I am not asking just to be a smart donkey, just curious.

I used a 300MHz laptop that certainly wasn't fast by any account but tiles
loaded faster than I could drive over them and I wasn't waiting for and
grass to grow. Moving up to a slightly faster netbook and speed was still
not an issue. So I truly don't understand.

Doesn't RadioMobile use vector contour lines? I don't remember.

What he said...

I prefer the fastest/smallest vector dataset that will do the job. It
may not be the prettiest when rendered, but I'm more interested in
useful data and ultimate speed than "pretty". For me that currently
means OSM vector data in ESRI Shapefile format, with the appropriate
dbfawk's to render it the way I want in Xastir. I don't use, and don't
desire, tiles. I would like to have contour lines as well someday, so
may investigate adding support for USGS DEM's at some point, or
perhaps I can find ESRI Shapefile maps with the countour lines already
drawn for me, which is perfectly adequate (and faster).

The online Tigermap server uses old map data, but I wouldn't
recommend caching raster maps when vector maps were available
anyway.  The don't scale well plus they take up inordinate amounts
of space.

If you're after street maps, download the latest Tiger Shapefile
data available.  You'll need to get dbfawk compiled into Xastir and
make sure you find/download/create the dbfawk files that apply to
your Tiger data version.  There was some discussion about this a
while back so hopefully you can find dbfawk files that apply without
having to create them from scratch.

If you run into trouble, ask on this list.

[Xastir] Has tiger.census.gov/cgi-bin/mapper/map.gif disappeared?

[Joe Kirby]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

Upgraded to FC13 a couple of days ago. Xastir works fine with the
exception of the online TIGER maps. Wire shark reveals a 'pThe
requested URL /cgi-bin/mapper/map.gif was not found on this
server./p\n' reply to xastir's request.

Is this a coincidence? I am thinking that the server went away some time
ago and I was using cached data. When I upgraded FC I stopped using the
cache and now can't fetch new maps.

Is anyone else seeing this?

 I saw that once and then ran out of time trying to duplicate it

 we'll have precise georeferencing then, better than Tigermaps could
 deliver (due to their weird projection).

I can reproduce it by loading a Map Bookmark set to level 512. The
APRS layer is zoomed to 512, but the OSM layer is not.

 Rendered by a server, similar to how Tigermaps were done.

Ok, this makes sense as to why the standard xastir map caching is
used. I assumed [incorrectly] that it was loading tiles, for which the
normal xastir caching wouldn't be well suited. The server-render
explains the latency. I've installed map caching now and it's much
faster where it can take advantage of the cache.

All good ideas- but first I have to get code working that will map

number of ways- both within and external to Xastir.


Note that we either have to match our caching system, which I think
files by a string name, or modify our cache to do things
differently.

Also it would be good to write code that is general enough to use
for other things, like WMS tiles...  WMS could benefit from exactly
the sorts of things you'll be writing for OSM.  I suspect yet other

Re: [Xastir] [tiling] reading tiles slow

[Jerry Dunmire]

Not a bad idea. As each tile is retrieved it would be scaled to Xastir
dimensions, which would change the tile size to something other than
256x256, and then saved.
I would be happy to help anyone who would like to take on such an improvement.

I added dbfawk files for them into Xastir a week or two ago that

It's been mentioned on here several times.  Do a Google search for:

Then go to that site and drill down to the country and state.
Download just the file that has shapefile in the title.  Expand
that in your Xastir maps directory somewhere and then reindex your

You'll need the dbfawk files that are in CVS Xastir to render them

If you're running 1.9.9 then I assume you installed from sources?

If so:

Certainly could, if you're using the online maps.  Check again later and they 
may be present.  I believe they keep a cache of used maps and schedule their 
server to render more tiles if they are requested.

Try the OSM_tiled* maps instead.  I'm using the mapnik versions of those.  With 
those you get small tiles and Xastir stitches them together, as well as caches 
them.  Much nicer when you only move a little bit:  Xastir only has to snag the 
tiles at the new edge(s).

[Xastir] OSM maps: .geo files, local rendering?

[Jason KG4WSV]

Can someone suggest a method (or give me an RTFM reference) for
generating .geo files for OSM map server tiles?  I like the looks of
tangoGPS, and am exploring the use of one map tile set for both tango
and xastir (or more likely just using a tagoGPS map cache for an
xastir map base, since there's a fairly well defined tile interface).


I was also wondering if anyone has looked at installing a local map
rendering engine (e.g. mapnik) so that OSM maps can be used in an
offline mode?  I took a brief look on one of my systems (ubuntu, IIRC,
could have been CentOS), but it seemed like an all too typical linux
dependency death spiral, so I gave up fairly quickly.  If you've set
one of these up, do you have suggestions on which distro, a good
howto, etc?

I'm liking the looks of these OSM style maps, but if I can't have my
maps in an offline mode they're useless to me.

[Xastir] DB-Put/Get

[Brian Marble]

All,

 

Map Caching seems to be not working.

 

When running Xastir 2.0.4 I am receiving the DB-put:  method not permitted
before method's open handle and it's sister DB-get:  method not permitted
before method's open handle.

 

Xastir gives me Map not found in cache. when I move to a location that
should be cached. (You know, back and forth with the  and  buttons)

 

I have tried many ideas to change the build, in regards to the libdb
libraries. Then I do a completed build again.  My current build is with
libdb-5.1.so. I have the libdb-5.1:amd64  libdb-5.1-dev installed. No other
libdb versions are showing in dkpg --get-selections.

 

I am using a WMS layer I created in the dir Online.

 

Where else should I be looking to determine the cause of this problem? Is
there a known solution to this problem?

 

Thanks

[Xastir] Maps won't cache

[Skyler F]

I have xastir running on Ubuntu. I installed it there to get sound modem
working. I have open street maps on there and want to use them offline.

However, when I move from a zone that isn't cached to a zone that is, all
of the cached maps are deleted. This did not happen on Mac, just Ubuntu.

Is there an option that I have set wrong or is there a bug in xastir? What
good maps with roads, lakes and more does anyone recommend that I can
download offline? If the open street maps offline is not going to work, I
guess I have to find something else.

I am trying to get xastir working for an event coming up, but there are
just too many issues I have been encountering, and I don't know how to do
anything.

Re: [Xastir] Script to cache some maps

[David Ranch]

I think if Skyler's script automation was slow enough, it shouldn't be a 
terms violation.   It specifically says "significant areas of tiles at 
zoom levels of 17 and higher".  It's unclear what "significant" is.  
Maybe we should reach out to their Sysadmins to get some clarification?  
I personally don't think this would really be all that much load if it's 
throttled properly and maybe limited to fetching the requested title 
zoom levels on a per-grid-square region.

Re: [Xastir] Script to cache some maps

​https://metacpan.org/pod/distribution/Geo-OSM-Tiles/downloadosmtiles.pl

Looks like there's an existing script ​that can download OSM tiles.  I have
not tried it, and if it works I would use with care given the tile usage
policy.


Interesting.. so I wonder:

  - Where you would need to run that program in to places the files in 
the correct Xastir path

 ~/.xastir/OSMtiles/mapnik/

  - Would the resulting files be in the proper format to Xastir to use 
them

 looks like it since it writes png and Xastir uses png


There doesn't seem to be any network / tile throttling support so I 
guess one would need to specify one region at a time, sleep a while, do 
the next zoom, etc.  Looks pretty promising though!

Looks like Geofabric also has shape file data, which xastir can consume.

IIRC, some of the OSM derived shapeless that used to be available were
problematic because the shapeless were inconsistent in a way that made
dbfawk (the method xastir uses to render shapeless into something other
than identical lines and points) development difficult.  Maybe this has
changed and it is worth looking into if someone has time.


My personal plan was to check into the approach mentioned previously by
Jason G, which is to set up a tile server.  possibly in a VM (virtual
machine). The nice thing about a VM from my perspective is that I'm already
running xastir in an ubuntu VM, so adding a fileserver VM would be
negligible additional overhead.

You missed the initial post and you have fallen for the "everyone is always
online", "bandwidth is plentiful", and "bandwidth is free" fallacies.

A full set of tiles (that's global coverage and global zoom levels) is not
practical to store (many TB or PB) - that's why the tile servers
(OpenStreetMap, etc) don't do it that way, and instead choose to generate
the requested tiles on the fly.
