The primary function of the Jc2 Map Viewer is its ability to read world files. When you have a scanned paper map, the image itself doesn't know where it is on Earth. The world file (e.g., topo_map.jgw ) tells the software the pixel-to-coordinate scale, rotation, and location. The viewer instantly warps the image correctly in memory, allowing users to overlay crosshairs on precise latitude/longitude or grid coordinates.
The user interface is straightforward. After loading your save, you can select which collectibles you wish to see on the map. You can filter the display by categories such as armor parts, weapon parts, vehicle parts, or cash stashes. One of the most useful features is the ability to "Toggle Settlements." This highlights which settlements are not yet 100% complete and, when clicked, provides detailed information about the specific items you are missing within that location.

However, finding 100% completion—specifically the infamous 75% completion barrier required for the "A Just Cause" achievement—is notoriously impossible without external tools.
It saves hours of frustration, making the road to 100% completion a more enjoyable experience. How to Use JC2 Map Viewer
