Thread: how to create IMG with some tiles of another IMG

This is the easiest way to make an "IMG" file.
There are enough free TOPO maps out there.
The example I use is France,Spain and Portugal Topo map.
To make the "IMG" file I use Garmin MapSource

I open MapSource load the TOPO map.
Then pick the area I want to use.
If I pick to much I can remove items not needed.

Spoiler: Pick the are you want

Spoiler: compile the IMG to your GPS

This can be done with any free TOPO map.

The example I used is from this wabsite:

I download this TOPO map

OFM(EU2021_SW_GPS).zip 08-Apr-2021 1,9G S. France, Spain, Portugal

Spoiler: It is a complete IMG file.

I then use GMapTool and cGPSmapper to un-compress the "IMG" file to be used in MapSource.

It makes a install for your PC or Laptop.

You will need the free version of cGPSmapper installed first.

Then set it up in GMapTool

You are all set to split the TOPO map to be install into MapSource.

Pick the tiles you want to work with and you are done.
No need to make a map from scratch.
