Can you please clarify to me what you mean by data that is oriented?
When I built the road layer from GPS data, I added polylines starting
from point A->...->B and recorded all the inflections in the road
between A and B.<br>
By ordered data you mean the direction in this case is A->B?<br>
If I wanted to reverse the direction I'd have to write the data to the
shapefile in the order B->A?<br>
<br>
Thanks<br>

<pre wrap="">it's the direction of the underlying geometry that's used.
so you either need
* data that's oriented, and a single boolean filed indicating if its
oneway or not,
* or an unoriented geometry, and a field indicating if the oneway
direction is reversed or not wrt the geometry (and two directional
symbols, one with > , the other with <)

<pre wrap="">Hello Thomas,
Thank you very much for your tip! It's great.
However, I have a question: How can I select the direction of the arrow? I
mean, between A and B I have a road segment:
A----------------B
Right now, it renders as A---->---->----->-----B, but I want it to render as
A----<------<-----<------B.
My question is: how does mapserver select the order of A and B? If I
understand this, I can create another symbol and use it for the reverse
path.
Thanks,
Adrian

Hi,
for repeated arrow symbols, you can use a truetype (or image, or
vector) symbol, with a negative GAP:
SYMBOL
NAME oneway
TYPE TRUETYPE
CHARACTER '>'
FONT arial
GAP -20
END
and then in your layer:
STYLE
SYMBOL oneway
SIZE 8
COLOR 0 0 0
END
cheers,
thomas

Hello everybody,
I have a map that displays roads stored in a polyline format. I would like
to mark one-way streets with an arrow symbol drawn on top of the road
itself. The symbol can be as small as possible (for beginning I would like
to be able to superimpose it anywhere between the street ends, and later on
I will lock it to be next to one of the ends).
I can already select the one way streets based on the following template:
CLASS
Name "OneWay"
EXPRESSION
/^FO040127$|^FO040132$|^FO040139$|^FO040120$|^FO040104$|^FO040131$|^FO040146$|^FO040129$/
STYLE
COLOR 255 0 0
WIDTH 4
END
LABEL
COLOR 0 0 255
TYPE TRUETYPE
FONT arial
SIZE 8
ANTIALIAS TRUE
POSITION AUTO
ANGLE AUTO
PARTIALS TRUE
MINDISTANCE 0
BUFFER 0 END
END
Can you show me an example of how to draw such a symbol on top of the layer?
Thank you
Adrian
