Advanced: Oine Maps
With GeOrg version you can use oine maps within the application.
This is useful if you’re geocaching in areas without network
availability or in foreign countries where mobile internet might be
expensive or not available at all.
Basically you download or create an oine-version of your favorite
maps within a given area. Then you put these "le onto your SDCard
and tell GeOrg where they are.
GeOrg understands so called Map-Tile-Packs. You can "nd some
ready to use Map-Tile-Packs on the andnav2-download-page. Just
download the pack you need and unzip it onto your SDCard.
Your own Map-Tile-Pack
If you’d like a real custom Map-Tile-Pack, you can easily produce
them yourself. Here’s how:
First download the Mobile Atlas Creator (MobAC). It’s a great
software and it’s free!
Select …
the Map source (e.g OpenStreetMap, Google, etc)
the area of the map you want to download
the Zoom Levels you need (higher numbers equal greater
zoom, but also mean much more tiles. The number of
downloaded tiles doubles for each further zoom-level you
select. You best start with “0″ and add single zoomlevels while
keeping an eye on the number of tiles, that would be
downloaded)
Now select the atlas format within the “Atlas settings”-section.
Right now (from GeOrg 1.1.8 on) you can select “AndNav
atlas format” or “BigPlanet SQLite”. Other formats won’t
work. (really important!)
… and add your selection to the Atlas’ content. One word of
warning: At least with OpenStreetMap there’s a limit on how many
Map-Tiles you may download from a given IP per day. Try to stay
beneath 100.000!
