First you need cGPSmapper.exe to work with Gmaptool.exe..... you can't convert to gdb from img.. you can only convert routable map files (gmapsupp.img, gmapprom.img...etc) to display in Mapsource... here is how to do it:-
- Open Gmaptool
- In
File click
Add Files and import your *.img
- Goto
Options and set the
Directory where
cGPSmappers.exe is located in your PC.
- Goto
Spilt > Directory- Select the
Output directory your Output map will reside
- In the
Create drop down menu select '
files for Mapsource'
- Tick and select '
Compile preview map'
- Enter a name for your Mapset in '
Mapset name'
- Click '
Split All'
- Goto the Output folder to find and run Install.bat - follow online instructions to enter Win registry for your new map.
- Check your Mapsource - if you have done everything correctly you'll see your new map.
Note:- download the latest version of the cGPSmappers.exe and Gmaptool.exe before starting to ensure compatibility. For Windows 7 users be sure to use the (x86) Install batch file.
Hope this helps.... I've not done this for quite some time now... a thousand apologies if there are errors...
... Cheers!
