POLYGONS AT INTERNATIONAL DATE TIME BOUNDARY

[Efren Serra]

George,

I think I figure something out:
setting EXTENT to -360 -90 360 90

and requesting layers in pair as (using WMS protocol):
BBOX=-360,-90,0,90&LAYERS=...&STYLES=...&TRANSPARENT=TRUE AND
BBOX=0,-90,360,90&LAYERS=...&STYLES=...&TRANSPARENT=TRUE
seems to do the trick.

Offhand I do not. I'm actually a sysadmin, not a cartographer, I focus 
more on the software and operating system than projections. :)

Would UTM zone 60 work? From there, the dateline would be at x=50000 and 
points east thereof would be, well, east as usual. Zone 60 should be 
EPSG codes 26760 (NAD27) and 26960 (NAD83/WGS94).
