G'Day Cobber,
That is the perennial question.
A google search will give this among a myriad of answers.
In a nutshell, there are several sources, updated years apart or as gross errors are reported.
I daresay that the data is gathered by the mapping authority of various countries and collated by the main entities.
For such a Herculean task, be assured it is not done in short term cycles.

Google Maps now gets all of their source map data from TeleAtlas. The other map data provider (NAVTEQ) supplies to Bing/Microsoft, Garmin, and others. TeleAtlas does seem to be much less up to date than NAVTEQ -- which means that Google Maps is often wrong. (A previous poster said Google Maps switched from NAVTEQ to TeleAtlas recently. That seems likely, as my entire neighborhood - which used to appear in Google Maps - has now disappeared!)

TO SUGGEST A MAP CORRECTION, you need to go to TeleAtlas (not Google):
