Mostly an interesting indoor activity which when forced to move outdoors can be kept interesting with GTA02 with many apps one of them is NeronGPS. Besure to cache all the places in the memory so it will be handy for on the spot tracking.
Requirement (tested with)
Application: NeronGPS
Device: ofcourse GTA02
Phone SW: QtMoko (v24)
Cache: SDcard (It can be configured in the nerongps.conf to point to flash memory)
SDCard that I use is SanDisk SDSDQ-4096-P36M
And a fix
As specified in /etc/fstab the vfat partition is needed for storing the below mentioned data
neo:~# ls /media/card/NeronGPS/
maps poi temp traces
in mmcblk0p1 and mmcblk0p2 for swap one can do away with swap. Even the p1 partition can be done away with if the info is stored in NAND.
To format the SDcard with GTA02 device in hand, follow the steps below
neo:~# fdisk /dev/mmcblk0
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x7928fdff.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
The number of cylinders for this disk is set to 121008.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

Restart again and you are done.
The map tiles were cached using WLAN and latter on used for referencing.
To upload the traces to openstreetmap or googlemap use the http://www.gpsvisualizer.com/ to convert the gpx file to kml(xml files) and use the import option in the google map and for the openstreetmap use the gpx directly.
Some of the traces that I submitted are mentioned below
[u-30-sep-2011]
This was the longest ever tracing done using GTA02 device. It was doing its assingned work exquisitely. The only preparation was for the backup power that needed to be given for the device and for me the backup was provided by the N148 plus (yep thats a netbook enacting as a charging device). So all along from TVM to CBE, was able to keep the device up and running with the fix all the way to the place - openstreetmap[1] and google.map[2], just that N148 was being drained completely without any other way to replenish its energy requirement. Its good to deactivate the display always on option because it drains the power quickly and I happen to notice that only in the last phase of my journey and it helped to conserve certain amt of energy.
Some of the screenshots are from the return journey (CBE to TVC) which gives a clear picture of how things where in real time.
Usually I really don't give a heck about what all places comes in between my src and dest. I mosly look at the ETA and ETD at src and dest and take respective action i.e to board or deboard the train, but this time it was more exciting for me to watch the places and even trace the places that is being followed. COOL!!!. The only thing was that the cache saved with zoomed tiles(upto 11) so could only see limited places and frankly I wasn't expecting the result as desired even more the "other passenger" who agreed not to kick me out of my place just near the window seat so that I will always have a fix but if I moved it little bit inside of the compartment the fix was lost.

[2] http://maps.google.com/
proceed further for more traces in the google.map
The conversion of gpx to kml by http://www.gpsvisualizer.com/ so as to submit it to google map was not happening because only 3M of data can be submitted but openstreet map simply accepted the gpx format. So did the following to reduce the gpx file size, so that gpsvisualizer can do its kml conversion(WTH, its another conversion from one xml format to another xml, this can programmed, will add it my ever increasing TODO list. Obviously accuracy is compromised with this kind of conversion )
