[mapserver-users] symbology showing line direction
I'm working in a GeoMoose application and trying to display utility lines with the correct line direction via some arrow character or symbol. I've had no luck so far. I've successfully labeled my lines with a truetype font character by defining the TEXT parameter in the CLASS object. I've also tried a pixelmap symbol definition using a .gif file. Both appear to work at first, but when you compare it to the actual line direction it isn't true in all cases. Has anybody found a way to accomplish this? I would appreciate if you could send me any examples. Adam M.

RE: [mapserver-users] symbology showing line direction
I was hoping it could read ESRI's From and To node structure much like ArcMap, but by the sounds of it that isn't possible. Shapefile geometry is saved in the Shape column, which I'm guessing is useless in Mapserver. What you're saying is I need to create an attribute and populate it with the angle of the line and use that to define my label direction? Adam M.

RE: [mapserver-users] symbology showing line direction
Yes it does work. The negative GAP value seems to be the solution. I
did not compare it extensively, but the areas I checked do appear
correct.

David, I had your opinion too, but Adam seems to have solved it. Adam,
do you confirm that you can display correctly directions?
2008/2/29, Fawcett, David [EMAIL PROTECTED]:
Adam,
I am quite sure that MapServer is not going to read the line topology.
To
display direction, you will need to add an attribute for flow
direction and
populate it. You would then use an expression for each class that
combined
both the pipe type and the direction. (Maybe use -1 and 1 for
values?)
Something like ('[FUNCTION]' = 'Main' AND [DIRECTION] = -1)
I haven't tested this. Note the difference in quoting for string
fields vs
number fields.
David.

David,
Below is my Layer definition. I've tried a truetype symbol and
label
with the ANGLE parameter set to AUTO or FOLLOW. Neither case pointed
out
actual shapefile line direction. I'm reading an ESRI shapefile so
there is
no specific column for line direction.

Adam,
What does your layer definition, with the classes look like?
Does your data have the direction column properly populated for all
records?
David.
