[mapserver-users] GeoJSON output from MapServer - GOT IT

[Dejan.Gambin at pula.hr]

Hi Steve (and others)

Finally I got GeoJSON output from MapServer. I have used the newest ms4w. 
The point is - I have already tried with this one, but probably didn't use 
FORMATOPTION or something like this. Now it works correctly.

A note - I had to use backslash notation for template FILE (on Windows of 
course)

That's it for now,

Thanks very much

regards, dejan
