[mapserver-users] symbology showing line direction

[Adam Feidt]

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?

A question: how can you derive a line direction by a shp without
having an appropriate attribute?
