For some reason, the Google Earth Road layers haven’t been staying synchronized with Google Maps. The only exception in the last few months I’m aware of is when Japan was added to both in September. During the last few months, Google Maps has added detailed road maps for Australia, New Zealand, South Africa, Singapore, Hong Kong, and Brasil. None of these locations are available with detailed road maps in Google Earth. I guess the process to convert road layer information into the vector format needed for GE is requiring more work. Either that or there are some sort of licensing issues. But, Google isn’t saying what the issue is – I’ve asked. At least residents in these locations can turn to Google Maps – however, on another rant: Google Maps still doesn’t provide a button to view the current location in Google Earth! Why is that?
