[mapserver-users] MapServer + Weather Data

[Paul Ramsey]

I am guessing you could do it with some clever SQL, which turns your 
weather information into values which map to your display requirements. 
You would want the wind speed mapping to letters which correspond to the 
symbols in your font set. You would then use that field as your 
LABELITEM in an annotation layer. You would also get the direction, and 
use that as the LABELANGLEITEM. The result should be the symbols you 
want, rotated in the correct directions.
