Hello,,
we are mapping global satellite data with postgis.
Is it possible with mapserver to change the color of the symbol according to
the value read in from postgis ?
Now the color is fixed within the mapfile reading only the geolocations i.e.
LAYER
CONNECTION "user=bla password=blub dbname=foo host=fum"
DATA "geocenter from table1"
CLASS
COLOR 50 150 150
SYMBOL "circle"
SIZE 5
END
END
My (maybe/probably ill) idea is something like:
...
DATA "value and geocenter from table1"
...
COLOR on value using "/dir/my_colortable.dat"
SYMBOL "circle"
...
But it looks like that only one coloumn of the GIS Table could be read for a
given LAYER.DATA statement.
Thanks for any suggestion.
Regards
Heiko
