is there a list of maps icons

I have had a look around and the nearest I can find for what you want is on the following link:

There is lots of information on that site, I hope it is what you are looking for.

Your query is not clear to me.

With the limited information that you have provided, It is hard to even guess the problems faced by you.

You're welcome. Glad I could help.
