Scribble Maps is a fabulous site that allows you to edit and customise your own Google maps. You can use the tools to draw on or to label any map available from Google maps. Maps can then be printed, saved, emailed, or embedded on a webpage or blog.
To use Scribble Maps, you do NOT have to create an account- you can save and share maps without any form of an account. If you would like to use Scribble Maps Pro, which has more features, then you do need to have an account but it is easy and FREE!
The zoom options and almost all of the search options available on Google Maps are available when using Scribble Maps. You can zoom in on any area and type text, change to different views (like satellite), and put markers and text at various locations.
