Google Maps has tons of features, but some of those features are not available in all regions due to many reasons. In order to help document what is and what is not available in certain regions, Google created a page named the Mapping Tool Availability to help you see which Google tools are available for mapping your area.
Google breaks the page down by several regions including Africa, Asia, Caribbean, Central America, Europe, Middle East, North America, Oceania and South America. When you open a region, Google shows you a matrix of what features are available in that area, features such as the Local Business Center, Community Edits, My Maps, Map Maker or Building Maker. Here is a screen capture of the North America matrix:
This will come in handy for the folks in the Google Maps forum and for local business consultants.
