It's probably this one. There is no online repository.

Ok, I have mapexplore 2.0 and I have a paris.map and several paris_*_*.gif files.
Now what do I do with them?
The guides only tell you how to deal with regular maps Arrow not google maps extracted with mapexplore.
Do I have to convert the gifs into pngs?
Do I have to join all the gif files together, load them in OziE to calibrate them, save them as pngs and then cut them back into 256x256 png chunks?
It's not making sense to me...
Why would I set mapexplore to give me 4x4=16 gif files of 640x480 pixels if then I would have to glue them all into a big 2560x1920 pixels just to cut them all again in the end into 640x480.
Again, this is not making any sense to me.
I guess I need help Confused
Cheers

You don't need to join the tiles

-Just choose the tile size (300x400 is optimal)
-Convert the GIFs to PNGs
-Upload them to your phone along with the .map file

Ok, now that makes more sense.
Do you know any free tool capable of batch conversion from many gifs to many pngs?
I've found "pngout" but it's a CLI tool and I'm having a hard time finding out how to batch convert, that is, if it's possible to do that Confused.
Thanks a lot for the tips, though Smile.
BTW, should I put the pngs and the map file all in the root of maps folders or should I put the map file in the root of map folder and all the pngs inside a subfolder?
Thanks in advance Wink.
Cheers

Forget it.
Just use:
Code:
for %i in (*.gif) do pngout "%i" /kp

That will convert all the gifs in that subdir to pngs maintaining the same name.
Neat, huh?
found it here http://advsys.net/ken/util/pngout.htm
Cheers

Im grabing maps from google using mapexplorer. I have a problem, that the tiles vertically overlaps a little. Various offset on various joints. Tiles fits perfetly in horizontal direction.

Im using Map Projection,Mercator. It does in wide range maps (6 degrees latitue). I dont see these overlaps in low range maps.

Im not using tiles dividable by 256 in any low or wide range maps.

I found a couple of bugs in mapexplore version 2, and thought I should mention them.

The first thing (small bug) is a ~5 pixel overlap between vertical slices. This can be fixed in Photoshop quite easily.

The second bug caused my latitude coordinates to be incorrect for the bottom values. They were actually larger than the top values (should have been smaller), and made the map position inaccurate.

I fixed this bug by modifying the map.html file, in the function generate_mapfile, line 549:

From:
Code:
var totallatsouthraw = yslice * Math.abs((latsouthraw - latnorthraw)) + latnorthraw;

To:
Code:
var totallatsouthraw = latnorthraw - yslice * Math.abs((latsouthraw - latnorthraw));


This corrected the latitude problem.

If it helps, my location was 51.046736 latitude, -114.066839 longitude, 15 zoom, 2000x2000 resolution.

Great program Smile, I'm enjoying using GPS with my cell phone.

there is certainly an issue with the Mapexplore2 code for for the southern hemisphere. Removing the Math.abs from the code below fixed the latitude for the southern coordinates for me. The previously mentioned fix did not appear to return the correct latitude.


var totallatsouthraw = yslice * Math.abs((latsouthraw - latnorthraw)) + latnorthraw;
