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:

Dave Fawcett's symbols from the old Mapserver wiki

Posted by HostGIS at 2007-08-09

This defines a pair of symbols which, when overlaid on each other, creates a thick line with a dashed line down the middle. This is appropriate for highways, for example.

SYMBOL
    name "circle"
    Type ELLIPSE 
    Filled true 
    POINTS
        1 1 
    END 
END

SYMBOL
    name "dashed"
    Type ELLIPSE 
    FILLED true 
    POINTS
        1 1 
    END 
    STYLE

Posted by HostGIS at 2007-08-09

Here's a method for drawing railroad tracks. THis is the usual line with shorter lines ("ties") across it.

        1 1

Swamp/Marsh fill pattern and Railroad

Posted by Bill Thoen at 2007-08-10

This is a self contained sampler of two symbol types. The first is a polygon fill pattern for swamp land. The second is a railroad symbol and while not particularly special, it illustrates the method of combining multiple styles to build up a decorated line type. The example consists of two files: a MAP file and its associated HTML file. Copy them both and then simply run the MAP file with mapserv to see the symbology.

Plane symbol

Posted by John Zastrow at 2008-05-05

I've been working on an improved version of the Itasca.map and taught myself how to make vector symbols (based on this excellent site! http://umn.mapserver.ch/index_en.php ). The symbol is below, but perhaps more importantly I created a little Excel to help me and included a brief explanation how to use it. http://northredoubt.com/mapserver/mapserver-vector-symbol-designer.xls

An improved itasca.map is also available (a work in progress) http://northredoubt.com/mapserver/itasca.map.html

Polygon fills: Marsh symbols, as used in orienteering maps

Posted by Håvard Tveite at 2010-10-13

Three different marsh symbols for polygon fills as specified in the International Specification for Orienteering Maps http://www.orienteering.org/i3/index.php?/iof2006/content/download/866/4026/file/International%20Specification%20for%20Orienteering%20Maps%202000.pdf. Exploits the way Mapserver is currently implementing vector symbols (using 0,0 as the upper left corner of the symbol, and the maximum x and y values as the lower right corner). Works well for GD. tile boundaries will appear at certain scales in AGG.
