I am working on a survey of manholes in a city. I would like to create a google map that the surveyors could view anytime they have questions about where they are working and the proximity to other manholes.  Is there a way to have a live map that I can keep updating, like with a kmz in google earth, that I could use for google maps, that they could view on their phone? Thanks for any help you can give.
