Hello,
I have a shape file with isohyets and want to draw only certain values
at different map scales. The larger the scale, the more detail I want.
Currently I use
CLASS
EXPRESSION ( ([value] = 250) OR ([value] = 500) OR ([value] = 750)...)
MAXSCALEDENOM 1000000
MINSCALEDENOM 500000
..
END
CLASS
EXPRESSION ( ([value] = 100) OR ([value] = 200) OR ([value] = 300) ...)
MAXSCALEDENOM 500000
MINSCALEDENOM 250000
..
END
which becomes a pretty long list in large scale class definitions, since
I got precipitation values up to 3000mm intervals.
Can I do something like
EXPRESSION ( ([value] = 'all values in 100 intervals')
Thanks,
Nils
