[GRASS-user] Calculate Median values in a State

[Andrew Lewin]

Hi All,

I want to calculate the median precipitation value from a raster layer  
in each state/province in a vector layer.

How would I go about doing this?

Should I convert the vector layer to a raster and then overlay the  
layers?

I would appreciate the help.

Thanks,

Andrew
