Is it possible to link AGTL to Ovi Maps so you can use navigation to take you to the caching location?

Oops, another question, yes I am playing with the AGTL application!

Is there a limit to the amount of openstreet mapping you can download? Today I am just getting the ' Could not load image ' message displayed.

I have found out that the amount of map data you can download is proportional to the amount of memory space left on the device and I have used it all up.

How do I delete some of the map tiles I have downloaded?

Webhamster, is there a way I can purge all data from AGTL and start again?

If you want to delete all settings and saved data, remove .agtl, like this:

rm -r ~/.agtl

(double check for spaces or spelling errors before running this)

To delete the map data, run

rm -r ~/MyDocs/.maps

Thanks, I have run the second command and have got back over 12GB of memory I am struggling to understand how to download the sections of map I want and seem to get an awful lot of errors Off to have a play again, I will crack it.

Downloaded 5 levels of map tiles for my intended destination in the Derbyshire Peak District, worked a treat. Good I did as could not get a signal at all where we were.

Thanks

New to geocaching, but this app is fantastic on the N900. Most impressed!

I have a kind of general question on AGTL.

I notice that if I deny GPRS connection (if abroad or there is no signal), AGTL really struggles to get a GPS fix. In fact abroad it failed after waiting about 10 minutes.
To get a fix abroad I had to start Ovi maps, which succeeded eventually in getting a fix, then started AGTL, then closed Ovi. This had me worried for a while that I couldn't get GPS fix!

But if GPRS connection is active, a GPS fix takes 1 to 2 seconds.

What information is being sent/gathered over GPRS to enable such rapid fix?

My handheld Garmin GPS takes a long time as normal to find a fix, especially if I have driven a long way with it off, so the GPRS is obviously helping a great deal.

Hi!

AGTL only relies on the built in GPS receiver routines, it doesn't send or receive any gps related stuff. It is correct that the phone uses AGPS to get a faster fix (see this forum or google for mor information). This is why there's data send and received.

As OVI maps uses the same routines, it is unlikely that starting it will speed up signal acquisition for AGTL. On the other hand, OVI Maps can sometimes display a fix when AGTL doesn't. This is because AGTL is pickier about the quality of the fix. The first fix is always a very rough estimate of the position based on the current cell tower. As this is useless for geocaching, AGTL filters those fixes out.

I hope this clarifies the situation a bit :-)
