3 little Questions

[Michael Schulz]

Hi Leopold,

Q1: you will need to use a style that uses a vector symbol, e.g.

SYMBOL
   NAME "circle"
   TYPE ellipse
   FILLED true
   POINTS
     1 1
   END
END

then you can use the SIZE parameter in the mapfile on that symbol.

Q2: Are you sre mapserver finds your shapefile in ./data? Did you try to 
use an absolute path to your data directory?

Q3: Not sure, but did you try using a 24-bit output format, e.g. png24 ?

Cheers, Michael
