[Mapserver-users] Virtual Spatial Data - projection

[Doug Cates]

Your coordinates have the x and y wrong. Chicago O'Hare airport is at:

lat/long 41.9795833 / -87.9044722

Which should appear in your table like:

x             |        y
-------------------------------
-87.9044722   |   41.9795833
