Hi all! My mapfile successfully outputs a map in Winkel Triple projection using the parameters below. Extent BBOX units are in meters as this is what the projection seems to output. What I would like to do is change the units to DD and set the EXTENT to -180 -90 180 90 (world view DD) but when I do so I get an empty map. Can anyone tell me if what I am trying is possible? And if so what I am missing (perhaps the obvious)?!
Thanks for your help. cheers, Mark PROJECTION "proj=wintri" "ellps=WGS84" "lat_1=50" "datum=WGS84" "units=m" # this is what I'd like it to be in "units dd" END SIZE 600 400 EXTENT -20000000 -11000000 20000000 11000000 # this is what I'd like it to be in EXTENT -180 -90 180 90
