Re: What can't you do on Android WITHOUT a Google Account set up in the OS?

VanguardLH,

(1) a test with the GPS of a tablet I had didn't give me much
confidence in its accuracy.

The magnometer periodically requires re-calibration (the 3-D figure
8 roll) to get compass readings correct.

Are you saying that the (functioning of the) GPS is dependant on the compass
?

Similarly, sometimes the A-GPS table needs to get re-downloaded.

I know that most "smarthone" GPS-es are actually A-GPS.   At the time I had
no simcard in tablet, meaning it worked in its off-line mode (and expected
its GPS to work well, out in the open air).

There are lots of GPS apps available

Thats another thing I'm not prone to: running random apps.

I have no idea what they actually do, and, on that tablet, next-to-no
possibilities to check and/or disallow certain stuff.  Combine that with my
stance that an app being allowed on-line is a privilege, not something they
may demand.

For GPS traces, I'd start here:

Thanks, but I already found a working description of how to do it.

Damn, I wanted to post the URL I found, but had to find that the page has
gone. :-(

Ah, it seems to have been relocated to here :

I saw uploaded traces, and where you upload them, at:

https://www.openstreetmap.org/traces

Uploading a nice trip isn't quite what I was trying to do.  Remember, I
didn't trust the accuracy of the tablets GPS, and thus the trip data - a
difference of just a meter or two would be a footwalk going next to a
building, or straight thru its walls. :-) :-(

No, I extracted the nodes from map data for editing purposes (max size just
a few KM squared), and wanted to return those, plus some "guestimated" new
ones, to them.

For editing the database, I'd start here:

:-) For "some reason" (i'm a hobby programmer) at that time I did not like a
ready-to-use map editor (I seem to remember I also found a list of map
editors), but wanted access to the raw data.

For help from their community, I'd try here:

Thanks.   But that one is for /users/ of the OSMAnd map program, not for
people who want to five a bit deeper.

Heck, I would be rather surprised if anyone there would even know what the
URL is to the "diff" files OSMAnd itself generates - or what the files
format would be.

I didn't find (but didn't look that hard) for info on the structure
of the database, or of exported data (which I suspect is XML).

Same here.  I did find /some/ info, but not of the current map format(s).

Remember that I quit using OSMand, so the above is what I found
in online searches.

I have no problem with that.  Information, even if its older, is better than
having none at all.

Though I, just like you, did do some major searching, and (effectivily) came
up empty-handed.

So, thanks for the info.
