Microsoft Virtual Earth does not work at all with the Safari browser.
There is some indication that the next version of Virtual Earth
(ver. 6) will support Safari. In the meantime, for Safari users,
all maps and photos will be provided by Google Maps.
For areas outside the U.S., Google seems to offer the best quality
aerial photographs, but the worst maps. For Google, even our close
neighbor Mexico is a big blank area when it comes to mapping cities
Within the U.S., the quality of aerial photos varies and it is
often a toss-up as to which provider will offer the best
quality. That's one reason I made this page so it will be easy
From a developer's point of view, the Google Maps API is more
advanced, offers more flexibility and has better documentation
than Microsoft Virtual Earth. It is also
more likely you will find information on the web about using the
Google API posted by other developers.
I originally set up this page to also include Yahoo! Maps, but
ran into several difficulties: (1) Yahoo! Maps photos displayed immediately
after Virtual Earth photos did not render correctly for reasons I never
figured out. (2) In Firefox, several problems arose from
that Virtual Earth adds (atlascompat.js) for Mozilla-based browsers.
(3) Yahoo! Maps zoom values are the reverse of Google Maps and
Microsoft Virtual Earth (i.e., 1 is the greatest magnification
and 16 is the lowest).
