Hi Edward,
Thankyou for the guidance.
I have used a graphic for Bridge point, but not consists of several line
geometries (in our data bridges are surveyed and it is a point feature
layer). I am interested to covert symbol into typeface, but the irientation
problem will reappear again like now i am facing.
Right now, Andrea's idea has solved my problem (calculating angle in one
column and using it in SLD to rotate bridge symbol perfectly with respect to
roads orientation angle)., but if we have country data with 5000+
bridges...its a big task.
So i am thinking & searching for other alternatives too.
Thanks & Regards,
Hari.
