Google Earth A to Z: Android, Antialiasing and Anisotropic Filtering

Google Earth was first released for Android in early 2010. Since then it’s gone through quite a few updates. It now supports KML files and even shows 3D buildings if your device is powerful enough! You can download it for free here on Google Play.
Anti-aliasing is a technique used to smooth the edges of features in an image. In Google Earth, this is particularly noticeable on 3D models. For example, here is part of the Georgia Aquarium with Google Earth’s Antialiasing set to “medium” on the left and “off” on the right. You can clearly see how much it improves the appearance of the building, though turning it off will help things to run a bit more smoothly. You can turn it off in the main [Tools] –> [Options] menu.


Anisotropic Filtering
Anisotropic filtering is one of those cool features in Google Earth that most people don’t understand. In short, it helps keep things sharp when you’re viewing imagery from a low angle. Here is an image from the anisotropic filtering Wikipedia entry, comparing it turned off (on the left) and on (on the right):
