N.B. This KML shows only a subset of the types/resolutions available in Google Earth

As you browse the earth you will notice some places appear clearer than others.

Currently Google Earth does not have the whole planet in high resolution. Although please bear in mind, more images are being acquired all the time and the database size being increased and updated.

There are many resolutions from many different providers, but here I have put together a placemark file to open which contains information about the main resolutions you will encounter in Google Earth.

Please spend some time looking at the descriptions in the placemarks.

For the latest imagery update news, check out the Google Earth Blog

Happy flying!

Thank you,
Phil
