Hi Mike.. Thanks for previous help. I have a another query which is mentioned below.
In my application i am placing few random markers by using the advise from here http://gmaps-utility-library-dev.googlecode.com/svn/tags/mapiconmaker/1.1/examples/markericonoptions-wizard.html. It works fine but i also want to prevent marker placing on the ferry routes( sea routes). because this random marker is placed only at the location where Driving directions is available. So it is also places on the ferry routes. That i don't want. you can see random marker placing feature in my current application here http://ws.viamente.com/demo/. So is there any way to identify the location which is sea route or land route? Thanks for kind support to all.
