05'06.30" W).
You can choose the Degrees option to display geo-coordinates in degrees decimal (e.g., 37.421927° -

Terrain quality - Use this slider to set the terrain quality to be lower (less detailed) quality with better
performance or to be higher (more detailed) quality with slower performance. To adjust the appearance
of hills when you have terrain turned on in the 3D viewer, you can set the Elevation Exaggeration value
from 0.n to 3.0, including decimal values. The default setting for this value is 1. Typically, settings higher

). To
do this, follow the steps below:
1. Click Tools > Options (Google Earth > Preferences on the Mac). Click on the Cache tab.
2. Enter a value in the Memory Cache Size field (
). You do not need to know the
actual limits of your computer's memory because Google Earth automatically limits the size according to
the physical memory available on your PC.
3. Enter a value less than 2000 in the Disk Cache Size field (
Increasing the size of memory or disk cache can improve performance but can adversely impact the
performance of other applications. Available memory is dependent on the specifics of your computer.
Increasing memory cache significantly improves performance for
Pro and Google Earth EC. Disk cache is limited to 2GB. Google Earth uses this cache when you are viewing
imagery offline. This enables you to view the earth without an Internet connection.
You can recover some disk space by deleting the disk cache. To do this:
1. Click File > Server Logout.
2. Select Tools > Options (Google Earth > Preferences on the Mac). Click on the Cache tab.
3. Click Delete Cache Files.
