[ka-Map-users] Ka-map and AGG?

[Lorenzo Becchi]

Hans,
have you created the OUTPUTFORMAT AGGA in your mapfile?
have you put MEDATA format "AGGA" to your layer's metadata?


another problem could be that it seems you're using MS4W.
I've tested on Mac OS X and I guess Sacha did it in Linux. Am I wrong? 
hopefully, I am

ciao
Lorenzo
