  property Zone : Integer read read;

PURPOSE:Specify which 6° longitude zone for UTM. Zone 1 centered at -177°, Zone 30 at -3°, Zone 31 at +3°, Zone 60 at +177°.

BEHAVIOR:Sets CentralMeridian automatically based on zone (e.g., Zone 33 → -15°). Range: 1-60. Setting zone changes CentralMeridian property.

USAGE:proj.Zone := 33; (for Central Europe)

CONSTRAINTS:Only for UTM projections. Values outside 1-60 may be silently clamped or ignored.
