Re: Maemo Mapper Mod - the new map file format
That's basically what I did. I never download maps using N800 actually, all my map tiles downloading, poi...are managed on PC. But even that, MM2.x can not be comparable with MM1.4 in the speed.
I...

Re: Maemo Mapper Mod - the new map file format
That's probably one of the issue panning is slow. Even you downloading couple of tiles, it does a sync, which I really don't like.
Another thing MM2.x does a rotation calculation(even it doesn't...

Re: Maemo Mapper Mod - the new map file format
It's in the MM2.x application code. The old gdbm always sync the data with disk no matter how small change it is. The gdbm 1.8.3 seems to give user some choice and provides a sync command(basically...

Re: Maemo Mapper Mod - the new map file format

Re: Maemo Mapper Mod - the new map file format
LOL, that's right. I see John has little interest in touching MM1.4 again.
My Mod is basically to bring MM1.4 back to "modernization" to be useful . MM2.2 is just not for me, it's slow and keeps...

Re: Maemo Mapper Mod - the new map file format
What I dislike most is the GDBM header, it contains all the important information and locates in just one allocation unit. So each tile update it needs to write to the header once, you have 50k...

Re: Maemo Mapper Mod - the new map file format
That's what I mean, the number of writing, but has to be to the same location.
The GDBM uses default allocation unit size as the hash table(bucket) size, normally it's 32k on a SDHC card.
Each...

Re: Maemo Mapper Mod - the new map file format
It's optimized for 32k allocation unit for the best speed and balanced waste space. The purpose I did that is I am still using MM1.4, and it consumes quite astonishing disk space. MM2.2 is slow...

Maemo Mapper Mod - the new map file format
Not quite happy with neither MM1.x nor MM2.x map repository format, I decided to write my own one. It went on and off for more than a month, now it's basically done. BTW I ported MM1.4.7 to os2008...

Re: Maemo Mapper Windows PC toolset
There is a 4 level difference between the two map formats. In MM2.x level 6 corresponds to level 2 in MM1.x, so you need to have map tiles in MM1.x repository of level 2 and under to have them shown...

Re: winmapper
Winmapper stores the map tiles in MM1.x format, which is not compatible with MM2.x that you're using.
I've done a tool that can convert it into MM2.x gdbm database. You can use that:

Re: Maemo Mapper v2.2 for OS2006/OS2007/OS2008
I am developing a new map file system for MM2.x right now, and want to plug it into MM2.2 to see any improvement.
I still like MM1.x file system, which is a lot faster. The draw back is the size...

Re: Maemo Mapper Windows PC toolset
Carefully check your config file path, if there is space in it, you may need to quote it, like
d:\maps\"google street"\map.cfg
Besides, it only supports Ascii coded path, not multi byte...

Re: Maemo Mapper v2.2 for OS2006/OS2007/OS2008
If you never delete any map tile in db, then there is no gap, just the nature of gdbm, which becomes slower when the db grows too big.
If you used to delete the maps within it. Then you need to...
