The Symbology Exchange: Vector Symbols

Welcome to The Symbology Exchange. This section is for vector symbols. Post your cool symbols here. We hope you find something useful.

Guidelines:

• Please post a description of your symbols. While "railroad" is useful, it doesn't indicate how your railroad symbol differs from anyone else's. Is it just different? Does it handle antialiasing and transparency at the same time? Does it look good at a wide variety of sizes?
• If you can post a link to see your symbol in action, that would be great.

Nice roads

Posted by HostGIS 2007-08-08

We use this styling for our roads. It gives them that nice thick effect, a la Google. The far-out roads are beige-yellow in color, giving way to grey-on-grey for the smaller roads.

The classifications used here are oriented around conventions used in the USA's TIGER street data: the CFCC field indicates the street's type, and range from A1 (interstate highway) to A7 (small road). It should be easily adaptable to other road data, though.

First, define a symbol for "solid":

SYMBOL
  NAME "line_solid"
  TYPE ellipse
  POINTS 1 1
  END
  FILLED true
END

Now for the classes and styling:

CLASSITEM "CFCC"
