[Geomoose-users] Expressions

Wed Aug 20 11:23:07 EDT 2008

Hey Jay,

What you want is what I wrote earlier.  Please (and I'm saying this as nice as I can come up with to phrase right now), keep your confusion limited to one or two message list postings.  I had to really struggle to go through all of them and determine which iteration of what particular solution you were trying.

MapServer will use a class without an expression as the "else" clause. So..

LAYER
    CLASSITEM "DIAMETER"
    CLASS
        EXPRESSION '6'
        ... this won't render anything as there are no style/label directives ....
    END
    CLASS
        # No Expression
        LABEL
            ..... stuff you want in here.
        END
    END
END

OK I got it to work….well got it
label a specific value in the DIAMETER field.

Now is there is a way that I can
write 2 EXPRESSIONS that will say don’t label 6 and the second say label everything
else?

I get this to work:
But I get the errors when I try
to create the expressions to limit what is labeled…(see former email below)

First off I am just trying to
get the EXPRESSION to work for the labels.
Second I am trying to avoid
writing 15 different expressions
That’s why I was trying create
an EXPRESSION that said label everything except values = 6

LAYER # Watermain_Pipe

     #NAME Watermain_Pipe

     DATA './watermain_pipes.shp'

     STATUS DEFAULT

     TYPE annotation

    MAXSCALE 4000

    MINSCALE 100

    LABELITEM 'DIAMETER'

    LABELCACHE ON

CLASS

       LABEL

TYPE TRUETYPE

FONT vera_sans

ANGLE FOLLOW

POSITION AUTO

MAXSIZE 7

SIZE 7

MINSIZE 7

ANTIALIAS TRUE

COLOR 0 0 0

BUFFER 2

       END

     END

END

Actually,
that will exclude anything with a 6 in it.

An easier way to go...

LAYER
    CLASS
       EXPRESSION '6'
        # Leave this blank
    END
    CLASS
           .... everything
else ....
    END
END

I think that should do it.

Yep, you just use a regular expression: /[^6]/

This is a mapserver syntax.

Is there a way to form a NOT statement in the expression…

To say for instance…show me all but EXPRESSION “6”

Instead of having to write each one out that you want….say I
have pipe sizes 1-30 but 90% are 6 inches….jsut show the ones that are not 6
iches…
This should decrease the amount of labeling I have to do

     CLASS

           LABEL

        EXPRESSION "12"

TYPE TRUETYPE

FONT vera_sans

ANGLE FOLLOW

POSITION AUTO

MAXSIZE 7

SIZE 7

MINSIZE 7

ANTIALIAS TRUE

COLOR 0 0 0

#OUTLINECOLOR 255 255 192

BUFFER 2

         END

     END

     CLASS

         LABEL

        EXPRESSION "16"

TYPE TRUETYPE

FONT vera_sans

ANGLE FOLLOW

POSITION AUTO

MAXSIZE 7

SIZE 7

MINSIZE 7

ANTIALIAS TRUE

COLOR 0 0 0

#OUTLINECOLOR 255 255 192

BUFFER 2

         END

     END
