Hello, we are talking in the Mobile Atlas Creator thread about the opportunity to create an export format in the program to be used with some . gps application that supports offline maps.

The first step is to decide which application is the best suited to import Mobile Atlas Creator's maps, so i collected some info, if anybody does know some good . apps that support offline maps please share your info.

Here is what i found so far:

-xGPS: http://xgps.xwaves.net/index.php/Main_Page
this apps only works on jailbroken iphones and it's available on cydia for free, it supports offline google normal maps and terrain (no hybrid or satellite), it does aready have xGPS Manager, a software for windows, mac and linux ( http://xgps.xwaves.net/index.php/Downloads ) that can download offline maps and copy them to . (still, only from google normal road maps and terrain), i havent figured out the format yet, it saves all in single file called xGPS_map.db.
This is an example of a small google road map i just downloaded:
http://dl.dropbox.com/u/5582036/xGPS_map.db
The apps for . works pretty well and straightforward, it has some nice features like gpx tracking and logging, zoom in and out etc.

-MotionX GPS: http://news.motionx.com/category/motionx-gps/
This is a paid app (2.99$) available on . appstore, it also has a lite version for free, both support offline maps but the lite version only 1 map tile set with up to 300 tiles, while the full version 50 map tile sets with up to 1000000 tiles per set.
The offline maps download is only supported from inside the ., but the maps can be accessed if your . is jailbroken (maybe there some way to access them even if it's not), anyway i already extracted the downloaded maps from the . to see if we can figure out the format.
This gps apps is very good and does have a lot of features, more than xGPS and it's constantly updated, it uses Openstreetmap as offline maps, while all version of google and bing maps can be used in online mode.

-Twonav gps [url] http://www.twonav.com/?op=2_0&lang=0en&prod=712[/url] mentioned by cragganmore
I dont know this app but it looks very good and complete, i havent tried it yet because it's quite expensive (50e) and there is no trial version so i cant say much about it, it can be used with CompeGPS Land software for windows to copy maps to . but you must buy most of the maps.
I dont think it's a viable option because it involves too much expensive
commercial software but correct me if im wrong.

This is what i found so far, please add any application for . that you know of, or your opinion about the options i presented, also would be useful if anybody know anything about the atlas format used in these applications.

I just realized that xGPS Manager, the software used to download maps and transfer them to . is open source, and here you can see the source files:

http://xgps.xwaves.net/download/xgpsmanager/xGPSManager-1.1.5-src.zip

It's in java like Mobile Atlas Creator, so i guess it should be kind of easy to figure out the atlas format from this source files and create a compatible export format in Mobile Atlas Creator.

I would vote for xGPS now. No other tool is either free and accessible from outside of the phone (or able to download user maps from Mobile Atlas Creator).

The xGPS.db file is a SQLite 3 database. After dumping, it looks simple. In tiles, there are tiles in hexadump format.

PRAGMA foreign_keys=OFF;
BEGIN TRANSACTION;
CREATE TABLE tiles (x INTEGER, y INTEGER,zoom INTEGER,type INTEGER, img BLOB, PRIMARY KEY(x,y,zoom,type));

repeats:
INSERT INTO "tiles" VALUES(2163,1453,5,1,X…hexdump…);
end-repeats

CREATE TABLE maps (id INTEGER, name TEXT, zoom TEXT, type INTEGER, PRIMARY KEY(id));
INSERT INTO "maps" VALUES(1,'villa','2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17',0);
CREATE TABLE map_regions (regionsid INTEGER, mapid INTEGER, PRIMARY KEY(regionsid));
INSERT INTO "map_regions" VALUES(1,1);
CREATE TABLE regions_points (regionsid INTEGER, lat REAL,lon REAL, pos INTEGER, PRIMARY KEY(regionsid,lat,lon));
INSERT INTO "regions_points" VALUES(1,46.2043096748167,10.1204681396484,0);
INSERT INTO "regions_points" VALUES(1,46.1983691071302,10.1431274414063,1);
INSERT INTO "regions_points" VALUES(1,46.2069233211127,10.1517105102539,2);
INSERT INTO "regions_points" VALUES(1,46.2147635138914,10.1321411132813,3);
COMMIT;

Edit:
after analyzing the tile format, I would guess, that it is a direct ouput from the Java class org.eclipse.swt.graphics.Image. The unix 'file' utility identifies it as 'tile.bin: JPEG image data, JFIF standard 1.01' but no image editor I have can read it, nor the ImageMagick library.

I will add here the hex dump and athe binary representation of the first tile taken from the sample db.

Hello,

Bit Map for .: http://nixanz.com/./55-bitmap

can read OziExplorer-compatible ".map" files. I haven't tried it yet but according to the manual you can load the maps through the network.

Yes, he has written, that he is working on a desktop conversion tool so the size limitation will be resolved.
I have had severe problems with highly compressed JPEG (~6MB), the program has been crashing on my . 3G constantly.

Can't wait for the version 3

Finally! Galileo App is the right app!
You have to purchase the offline map support.

Mobile Atlas Creator 1.8beta supports its RMaps Sqlite format.

If you have iOS4, transfer maps via iTunes.
If you have . OS 3, jailbreak it, get access to the . Disk and transfer maps to the /private/var/mobile/Applications/XXX/Documents and change the files' owner to mobile.mobile via SSH terminal.

XXX is some strange number - you have to scan all the Application's subfolders. The right one is the one, where is the Galileo.app file.
