Oziexplorer is probably the easiest way.

See following thread http://www.trekbuddy.net/forum/viewtopic.php?t=2884

Basically, you just match points on your scanned map to the corresponding points on a Google map - and then it does calibration and creates TB atlas with one click.

Some time ago I wrote a little Windows program to convert calibrations from one format to another (e.g TFW to MAP, JPR to GMI etc). With the demise of GPSTUNER’s calibrator I’ve enhanced it to work as map calibrator as well. Extending it to write TREKBUDDY tiles is fairly easy but I don’t have a Symbian phone! Would someone like to test it for me? This version is not on the website (www.the-thorns.org.uk) but I will email it to you. You could, for example scan a UK map, calibrate it with OS grid references and get TREKBUDDY tiles with a WGS84 .map; or a TIFF and TFW from http://www.libremap.org/data/ and get the same. The app will be free.

...further to the above, I wondered if there is a need to be able to rescale and/or crop a calibrated map whilst retaining the calibration. Functionality I could add if there is a demand.

I'm having a rather large atlas where the layer with the highest zoom level consists of two maps, each having about 600mb, tile size is 240x320.

On my Nokia 6303 (S40) loading one of the maps on the highest zoom level takes about 3-4mins and I'm wondering whether I can speed that up.

I thought about 2 possibilites and I would appreciate feedback or other ideas:

1.) split the layer into a large number of maps. According to a friend this should result in a faster loading time. However it seems to me that this would require a lot of work, since I would have to run OziMapTrans for each of the maps manually. Or is there any tool to split a map into multiple smaller maps (incl. .map-files)?

2.) create a tmi file. From what I read here this only makes sense in the context of TrekBuddyService, which is only for S60, right?

Thanks for your help,
Stefan

Ad 2) No - tmi is vital for map loading on all platforms!

Interesting... I use E60 (the same Symbian as in N73), my default map has 147 tiles / 3.6 MB. Map opens in 2-3 secs, scrolling speed comparable to unpacked map.

And yes, file I/O really is somewhat faster in S40 than in S60 Confused

I guess there is more OS overhead in Symbian.

EDIT: E60, TB (with larger buffer for tmi reading), another map 140 MB, 20626 tiles, tmi size 800 kB, map opens in 5-6 secs, map scrolling accetpable...

Thank you all for your help, I got an incredible performance boost with the tmi-files.

My maps are around 80k x 50k pixels and they take ca. 25sec to load, which is ok, maybe I'm gonna cut them down to 10k x 10k as suggested - if only OziMapTrans had a one-click-way to automatically split a source into multiple adjacent maps Sad

@kruch: It would be nice if you could add the tmi-files to the HowTo on top of this thread. In fact OziMapTrans generates the tmi-files, but in the first place I didn't know what they were and removed them.. Embarassed

Could you add to the quick guide the ms-dos batch script to make .tar and .tmi autmatically from map and png?

It is explained here:

Hi kruch,

in tared atlases all the .map files exist twice:
1) Inside main-(index)-tar
2) Inside the map's tar file

What's the reason for this redundant information?

In untared atlases there is no central index and all map-files exist only once - why this difference?

I want to know does altas support auto zoom?

TB will auto zoom out but not in , if say you have 2 maps whole country at zoom 10 and city at zoom 15 if you go out of city map area TB will switch to country map

Hi, Im from Bulgaria and I want to ask where I can find or create maps of Bulgaria or just Sofia. I read it can be done here: http://gm2tb.awokenmind.de/
but when I find the map of Bulgaria or Sofia and try to download it it tells me this: http://gm2tb.awokenmind.de/gm2tb_createTAR.php?latitude_e6=49849956&longitude_e6=10876464&zm=2197266&w=2000&h=2000&cc=us&min_priority=2&longeastraw=16.36962890625&longwestraw=5.38330078125&latnorthraw=53.38332836757156&latsouthraw=46.31658418182218&mapname=mapname. Is there any other ways of fast creating of maps rather than google maps. Or is there a side or topic with ready for using maps for trekbuddy and btw I'm with Samsung s5620 Monte. PLS post a reply... :)
