I hesitate to ask for standard symbols, but is there a de facto standard symbol(s)? Or a popular set of symbols to use for electronic markers?

Our utility will soon start marking with electronic ball markers similar to these: (from Water World Article 'Municipality Marks New Pipelines for Future Access').

I found this one somewhere, but I can't remember where I grabbed it from:

Are there others?

USA Standards?? – Mapperz Jan 18 '11 at 14:59
USA for me, but I'll upvote others. – Jay Cummins Jan 18 '11 at 15:17

Here is what is in arcmap 10. But somehow I don't think that is what you are looking for:)

I looked through the ArcMap 10 symbols prior to posting the question. Are there electronic marker symbols in there and I missed it? – Jay Cummins Jan 18 '11 at 16:30
Duh, You said electronic not water or waste water. I'll have to learn what electronic markers are first. :o – Brad Nesom Jan 18 '11 at 16:51
The physical asset is called an electronic marker (as you can imagine, searching for marker returned a useless result set). So I'm looking an electronic marker (map symbol) to represent an electronic marker (plastic balls that are buried w/ the underground asset). – Jay Cummins Jan 18 '11 at 18:28

Unrelated question but I am looking for a directory or database of all the dots, crosses and squiggles that I find along the street or on walls of buildings. I've been photographing them and use them in my art.

Is there any website or a link to the arcmap 10 example posted in Brad Nesom's answer? Any other similar visual list of these types of shapes and forms would be deeply appreciated. Thanks!

It would be better to ask your own question and reference this one instead of posting your question as an answer. – blah238 Apr 4 '11 at 16:28
