AW: [UMN_MAPSERVER-USERS] attribut values

[Leopold Schefcik (MULTIMEDIAPLAN.AT)]

Hi Travis, thank you for your advice to make a map file for several classes.

I tried to make some for my file of inhabitant-density with two classes >200
and <200. (Mapfile in the Attachement)

But I get the error message 'msDrawMap(): Failed to draw layer named
'Bev_Density' '.

Is it right, that you don't have the line 'CLASSITEM "EWKM2"' in you map
file?

best regards - Leopold

If you are trying to display a layer with several classes you can try
something like this:


	LAYER
		DATA mattamy/road_web
		NAME roads
		METADATA
			DESCRIPTION "Roads"
		END
		TYPE LINE
		STATUS ON
		MAXSCALE 150000
		MINSCALE 40001
		LABELMAXSCALE 120000
		LABELMINSCALE 500
		LABELITEM "STREETNAME"
		CLASS							# HIGHWAYS/MAJOR ROADS
			MAXSCALE 120000
			MINSCALE 500
			EXPRESSION ([RD_CLASS]=1)  #if it is a string ('[FIELD]'='value')
			SYMBOL 1
			COLOR 75 75 75
			SIZE 1
		END

		CLASS							# SECONDARY ROADS
			MAXSCALE 120000
			MINSCALE 40001
			EXPRESSION ([RD_CLASS]=2)
			SYMBOL 1
			COLOR 100 100 100
			SIZE 1
		END
		CLASS							# LOCAL ROADS
			MAXSCALE 80000
			MINSCALE 40001
			EXPRESSION ([RD_CLASS]=3)
			SYMBOL 1
			COLOR 150 150 150
			SIZE 1

		END
	END

Hi list,

I have a database for a layer conisting of 5 files:
test_bevdichte3.dbf
test_bevdichte3.sbn
test_bevdichte3.sbx
test_bevdichte3.shp
test_bevdichte3.shx

In my map file I can give the path to the dbf file to clasify the data.

 CLASSITEM "EWKM2"

but still oll the polygones have the same color.

Somehow I want to configurate how many classes are build and with stile
every class has.

Somebody can give my a hint?

best regards - Leopold
