PRJ

PRJ (projection) files are used in FIFA Manager to identify how 2D map textures (for countries or continents) are projected onto the geographic coordinates. They are placed in fmdata/grids folder. They were introduced in FIFA Manager 08.

Structure

Each file consists of 144 bytes of data, which have the following structure:

DOUBLE Point 1 - X
DOUBLE Point 1 - Y
DOUBLE Point 2 - X
DOUBLE Point 2 - Y
DOUBLE Point 3 - X
DOUBLE Point 3 - Y
DOUBLE Point 4 - X
DOUBLE Point 4 - Y
DOUBLE Point 5 - X
DOUBLE Point 5 - Y
DOUBLE Point 6 - X
DOUBLE Point 6 - Y
DOUBLE Point 7 - X
DOUBLE Point 7 - Y
DOUBLE Point 8 - X
DOUBLE Point 8 - Y
INT32  Latitude - min
INT32  Latitude - max
INT32  Longitude - min
INT32  Longitude - max

All 8 points form a grid which is then projected to defined latitude/longitude coordinates. This data can be visually represented like this:

Longitude - min                       Latitude - max
   Point 1             Point 2            Point 3


   Point 8                                Point 4


   Point 7             Point 6            Point 5
Latitude - min                        Longitude - max
