Looks like Google Earth is soon going to face tough competition from a strong rival. Apple has just bought a Canadian mapping company named
Poly9. The company specializes in interactive 3D software designed to be used in browsers.
Poly9 (read Apple’s Google Earth) is a very lightweight program which uses only 303 kb of your browser’s memory. The application is cross platform, does not require any download and can run from
your iPhone as well. The
interface consists of a spinning 3D globe with comprehensive satellite imagery.
