Rename: Getting DBF data for symbology

[Todd Harris]

I have recently had the same problem with overlapping polygons at the
CLASS level, I solved it by using a hatch symbol that had a minimum
spacing value, thus allowing linework to appear through the hatching. It
will have a slight affect on the colour of the polygon on top but works
well.

 

STYLE

                                SYMBOL 'hatch135'

                                OUTLINECOLOR 0 0 0

                                COLOR 255 200 255 # light pink

                        END #STYLE

I believe that transparency/opacity currently is only available at the
layer level, not the class level as Hayden appears to want.  

 

If you really need the transparency option, you could break out your
classes into separate layers.  This would allow you to use transparency,
but would of course multiply the number of layers and may give you a
very small performance hit (which may likely be negligible).

	There are a couple of ways.

	 

	First is to set a transparency level, if the polygons have to be
solid.  Underlying polygon doesn't have to have any, while the top
polygon can have any transparency level you want - probably somewhere
between 40 and 60% if you want both to be approximately equally visible.

	 

	Or you can simply set an OUTLINECOLOR and no COLOR, which means
you will get an outline and no fill, which will show any underlying
polygons as long as they don't directly overlap the same lines.  Any
overlapping lines can be identified by making the outline line thicker
and a different color, so whoever is viewing the map can see that there
are multiple polygons there.

	 

	Regards,

		Also polygons on top of polygons, is there a way to make
it so you can see both?
