Incorrect positioning for maps calibrated using UTM coordinates in South hemisphere

[GoogleCodeExporter]

Hi,

I have a large number of Ozi Explorer maps for Victoria, Australia that are 
calibrated using UTM co-ordinates ( Zone, Easting, Northing ).

These maps load into Androzic, but the positioning is way out.
In the case of the example map provided, the co-ordinates of the top left 
corner should be Lat/Long 145.125064, -37.625051 but it shows up in Androzic as 
144.56xxx, 52.62xxx


What version of the product are you using? On what operating system?

Android - 0.9.10b

Please provide any additional information below.

Thanks & Regards,
Robin Clipsham

Hey there,
I'm using Hema maps. The Australia 250K maps do not calibrate properly with 
Androzic for me. (just like for the original poster?) It seems like OziExplorer 
does not have the same problem.
I can only upload the .map file, since the correlating .ozfx3 is over 100mb.
I'm using the latest androzic (Androzic-0.9.18b.apk), I have also tried 
0.9.10.1b, and a couple other versions. (between the two)

I have figured that all of these maps were using the "Australian Geocentric 
1994 (GDA94)" datum. I have changed it (using check calibration of map in 
oziexplorer) to WGS 84, and saved the files on my device.
It solves the problem on androzic, now all these maps calibrate correctly. I 
believe that it's a bug in androzic, because using the original .map files in 
oziexplorer gives the right coordinate and calibration, wheres androzic cannot 
handle it and sends those maps way off calibration.
I'm attaching a zip with the new and old .map files. the maps themselves are 
too big to use. I hope that it will help other users with the same problem, or 
help the developers figuring out the problem.
