Google Earth - A world exploration tool
Authored by: skapplin on Jan 23, '06 08:23:51AM

A major difference between the early beta version and the current version is resolution. The early beta version had resolution down to only a few feet. The current version's resolution is several hundreds of feet. Once you zoom in past that distance the images lose their visibility.

I guess to mitigate the loss in map resolution Google did update the maps by a year. However, some are still not current and at least one year out of date.

I don't use Windows so I don't know if these limitations are restricted to the Mac version.

Resolution varied depending on what you're looking at: some areas have aerial photography with resolutions of a a few centimetres, some use QuickBird satellite imagery - maximum resolution 60 cm - and some Landsat at 15m/pixel. There's no difference I can detect between versions

The data is stored on Googles server, it doesn't matter if you're on a Mac or PC you get the same satellite photos and the same height data.

I had this problem (in windows version, but I believe they use the same maps).

In the "Layers" pane, I found that deselecting the "Terrain" option made the maps (in some areas) appear in a very much higher resolution. (The same option appears on the bottom left hand corner underneath the map itself.)

I hope that this works.
