Sorry Kurt. You've evidently done a cut-and-paste for msg#2 from a 
word-processed source. The plain-text format of email doesn't like 
'curly quotes', substituting queries (?), and the source's word-wrap 
lacks a space character making words run together (among other manglings 
:( ), making for considerable difficulty in deciphering the message 
content. Can you paste the cut into a Text Editor (e.g kate in Kubuntu 
Linux, Notepad in Windblows) and cut-and-paste that into your mailer? 
Please?

Re: [Xastir] Some Pocket Chip Success

[Kurt]

Hey,
  I ordered a Pocket CHIP last summer for the heck of it and it arrived last 
week. Next Thing Co.   After getting through some issuesof flashing the thing 
with the 4.4 GUI  C.H.I.P. Flasher I got Xastir through apt-get.  It's a Debian 
Jessie distro and the 4.4 and 4.3 gui'swith Gnome run on the Pocket CHIP.  Just 
some issues with window size positions but I found putting the taskbar at the 
bottom of the screenworks better.  I had a situation when some of Xastir 
screens had to be repositioned and I couldn't get 'em closed.  I used the 
online OSM maps and APRS-IS.  It's not bad.  I'm going to try to pair with a 
B/T GPS to get the local position in and either aMobilinkd, AP510 or an 
EggFinder NMEA receiver for APRS or remote monitoring tracking.  One kicker is 
I had to use a standard USB or Rf USB mouse to get it going but was able to 
then pair a B/T mouse if I wanted to use it.     If I could configure the 
screens to be "draggable" with a mouse so I can get at some of the Xastir menus 
it would be nicer but I've just started outwith it.  I'll have to see if 
there's enough room to use some of the Tiger or Cloudmade maps of where I live.
  B/T I think will work o.k. for APRS and NMEA as I was able to get an old 
Royaltek B/T GPS paired and after I apt-get minicom, the strings weredisplayed 
beautifully in a terminal.
  Even though the screen is small, Xastir fills the whole thing and it's more 
usable than I though it would be.  Kurt

We "needs" something ready made that neophytes and the geographically, 
academically impaired can just drop in a directoryre-index and then go.  I 
still have around some of the old Tiger 2006 and Cloudmade maps from 2008 from 
mine and surrounding states.  It's just too derned easy to have a drop-in 
solution.I believe that's what keeps the program from being used by more folks. 
 I probably would have stayed away from the program yearsago if it weren't for 
the ready-made solutions available at the time.The Xastir compiling scripts 
were really great to get all the bits and pieces into the program so one could 
experiment.Kurt KC9LDH

On the topic of pretty offline maps, I have followed online directions to
setup my own local OSM tile server and then created an xastir mapfile to
point to localhost. It's not trivial, but if you are comfortable with basic
system administration and building codes it is doable.

Vector maps aren't all that pretty, but they're fast! No point in sending
an image 'cuz you'd be disappointed compared to raster maps as far as
"pretty".

Xastir has ESRI Shapefile capability built-in. This gives you vector maps
with one-pixel-wide all-black lines, displayed at all zoom levels.

To change the display of these lines so they are wider based on certain
parameters (number of lanes perhaps, rivers versus creeks perhaps), to
change the colors of objects, or to make some things visible at some zoom
levels but not at others, you use dbfawk files to do this. Also: If you
want any of the objects labeled you need dbfawks.

Hey Curt,

I've never used any of this dbfawk capability before but beyond it's 
offline ability, I've always been curious on it's performance benefits, 
maybe it's better looking than OSM, etc.  Could you post some screen 
captures of what things look like on your tuned dbfawk setup with a zoom 
of 128 compared to say Online/OSM_tiled_mapquest.geo (works well but 
always strikes me as a bit "dark".


Maybe when you have a good example of what can be done with dbfawk, you 
can check it into Git and I can load it in to check it out?  Though I've 
never used this feature, my Xastir build is fully featured so it 
"should" work.  (famous last words)

These seem to be fairly complete and are updated often. Gives you another
offline map option for OSM maps.

The initial support for geofabrik.de maps in Xastir's dbfawk files is for
"roads" and "waterways".

Xastir displays "buildings", "landuse", "natural", and "railways" as well,
but there aren't any dbfawk files for them yet so no labels, changes on
zoom level, colors etc for those. As far as "places" and "points": Without
labels they are useless.

What the maps are missing: Lakes and land masses. Here's what I did to make
a nice map stackup with offline maps:

*) Use the county Shapefile set from the weather alerts as the land mass.
In my case "c_05ap16". I just made a link from my map directory back to the
"/usr/local/share/xastir/Counties" directory where the weather alert maps
reside, then reindexed maps and those files show up in the Map Chooser.

*) Use "lk17de98" for the lakes. Don't remember where I got it but I have
it in maps/World/USA/ directory along with a bunch of USA-wide maps.

*) Enable "buildings", "landuse", "roadways", "roads", and "waterways" from
the geofabrik.de maps

*) Click on Map Chooser->Properties. Set layer for "lk17de98.shp" to 999
and for "c_05ap16" to 998. This makes the land get drawn first, then the
lakes, then the geofabrik.de maps.

*) Map -> Configure -> Background Color -> Navy Blue

Now you'll see ocean with land masses drawn on top, lakes on top of that,
then the other features drawn on top of that. Looks good and pans/zooms
fast 'cuz they're all vector maps.

There's a lot that can be (and should be) done yet with the dbfawk files
for geofabrik.de maps. I did the minimum tweaks to make them start working
in Xastir. Most of the lines in there are original lines from the files I
copied to make them, so those lines don't apply to the geofabrik.de maps.
