Tile Storage:
Possible solution to avoid too many files in a directory is to use a deeper directory structure of the tile cache.
That would work much faster than without those intermediate directories. |
Good idea. Simple and effective.
Kind regards |

tilestore:
Splitting tile files in different subdirectories is IMHO totally ineffective. AFAIK, modern file systems like NTFS, Ext2, ReiserFS... are working internally like a indexed database. Therefore the speed-up would be very small. Only if you (have to) use such relics like FAT it makes a difference.
I know for example that NTFS can handle 300,000 files in a directory without problem. The only problematic part is the graphical frontend (Windows Explorer, Nautilus,...)
My favorite for an definite solution of the "tilestore problem" is the Berkeley DB Java Edition. It packs everything in containers of ~10MB and is very fast.
@thomast:
If you are getting a tmi file you have selected the wrong atlas output format. Please check that you have selected "Mobile Trail Explorer" when pressing the "Create Atlas" button.
regarding how to use the created atlas please check the MTE web page: http://code.google.com/p/mobile-trail-explorer/
@start78 (Printing map selection):
Why not "export" it as png image (OZI PNG atlas format) and then print it with an image editor/viewer of your choice?

You are absolutely right about tilestore in separate files. Spreading them into different subdirectories has some benefits on FAT/FAT32 filesystems (one cannot put more than about 30.000 files in a directory, but this also depends on the length of filenames). Even the graphical selection of such a heavy filled directory can last minutes... I also vote for a DB solution, whatever you choose.
May I ask for a feature: I would like to just fill the tilestore (no Atlas creation), as I process the tilestore with my tool OziMapTrans. Currently I generate a tared atlas and discard the result.

So OZI format creates one big picture? Would be exactly what i need. Thanks! _________________ Nokia 5800XM (FW 21.0.025 T-Mobile Ger) / TB 0.9.89 / Atlas by TBAC |

Ok, I bit a lot of internal code clean-up and fixed a small bug in the SQLite atlas format handler. Therefore it's not a bad idea having a second RC before the final:
TrekBuddy Atlas Creator 1.6 RC 2
Changelog since v1.5 (those in bold are new to RC 2):
! Map selections do no longer unwanted enlarge itself in grid mode beyond the selected grid
+ Loading & saving of GPX 1.1 files (way- track- and routepoints are displayed as overlay)
+ GPX 1.0 files are automatically transformed to GPX 1.1 file on load
+ Route and tracks are painted as connected line
+ Add new way points to a GPX file (properties: lat, lon, name)
~ Behavior on adding new maps and layers changed: the number of layers has been reduced to a minimum making it easier switch between different zoom levels when using TrekBuddy
+ Map scale bar added (metric/imperial selectable)
+ New atlas format: Mobile Trail Explorer (MTE)
+ New atlas format: RMaps / BigPlanet SQLite (Android applications, requires additional SQLite libraries)
+ New atlas format: OSMTracker
+ New map source: OpenStreetMap Public Transport (öpnvkarte.de)
+ New map source: AustrianMap (z14 & z15 of www.austrianmap.at) [provided by Guenther Hoelzl]
+ New map sources: Freemap Slovakia (normal, hiking & hiking plus hill shade)
+ New map sources: Google Maps Korea

And again the YouTube video link showing how to use TAC:

Add please support for "http://mapy.atlas.sk/" (Slovakia only). There are also aerial maps of Slovakia in good resolution and without limit for download such as in Google
Thanks |

Hello,
how to work with the gpx tool ?
I can load tracks, but cannot save waypoints created with "add waypoint".
It is also not possible to rename a new gpx.
Best regards
Wunibald |

Hi elK,
the Garmin custom maps format is not that simple but it is possible to add. May be first only using one 1 megapixel jpg tile.
But currently I am focused on other parts of the program. Therefore please create a Feature Request for this atlas format at Sourcefore [1]. Otherwise I will forget it:

Hello users of TrekBuddy Atlas Creator.
Because this topic got a bit long - which makes it very difficult for new users - I decided to close this topic and start a new topic for the just released final version 1.6:
Please do not use this topic any more - use the new one instead:
