What I've been doing with AltoDroid is scrolling around at different zoom
levels at my area of interest (launchsites) to store as much as I can get.
When offline you go to the upper right menu pull-down and hit off line maps.
You'll get the map/photo, with the google watermarks across the screen. The
zoom levels are not as extensive as when connected on line but good enough for
tracking.Some may gripe about the watermarks but again I don't find them
intrusive enough to be a problem. Nice to be able to see if you have to cross
drainage ditches or creeks in advanced as sometimesit's not always best to go
in a straight line to the last known packet position of your rocket.
This is the only tracking app I know of that allows one to select and cache
maps for off line use. All the Ham Radio tracking programs one has to install
the mapsets before expecting to be able to use them off grid. Correct me if I
am missing one here.
Mapsphere allows downloading and caching but it doesn't navigate ie. only can
put one datastream on the map at one time. In other words you can see where
your rocket is but not where you are in relation to it on the map. Plus it is
no longer supported or being maintained.
APRSIS32 will allow one to hold tiles in the disk for off line usage later but
one has to triapse around with a laptop or input the data into a handheld GPS.
If should be more usable with the smallWindows tablet devices coming out now.
GPSGATE costs an arm and a leg to use so I haven't bothered to look at it.
UIView again has no commercial mapset available anymore so it's a PITA to do
DIY maps. Could do google photo map overlays with a commercial piece of
software but it was a royal PITA to do.The absolutely cool thing with UIVIEW is
one could use it as a base receiving station and actually record a flight in
real time and could play it back in real time. No other app does that.
Xastir is a Linux app of which I know Linux is dear to Bdale, Keith and myself
but is difficult for an uninitiated person to use. It too has off line mapset
issues of which I was able to download someworkable mapsets from several years
ago. It can be used for APRS tracking and with the use of a simple script, can
be used to track EggFinders and Eggfinder TRS devices that simply transmitthe
NMEA words to a receiving station. The script translates the incoming NMEA
words into a "pseudo" APRS packet that Xastir can plot on the screen. Kinda
funky to see the data coming in 1/sec as opposed to once every 5 seconds one
gets with APRS. Alternatively, one could just connect the EggFinder receiver
to the GPS port on Xastir but in that case one would be in the same positionas
Mapsphere.
YAAC has some potential for APRS as OSM maps can be stored for offline use. If
one can get it installed in a small Windows tablet and access the internal GPS
receiver so the device knows where it's at, along with pairing to a B/T TNC it
could be a workable receiving station for APRS tracking.
The above options are why I like the Tele-GPS/Tele-BT and AltosDroid solution.

I waited for a little bit longer and the menu filled up with all the choices.
I then selected the Kloudbusters site and a progress bar appeared and completed
the download. Now that I have downloaded the map is it cached on the phone or
will I always need a internet connection?
