How Google Earth Really Works
Don’t miss this article if you’re at all curious about how Google Earth works on a technical level — how data measured in terabytes and terapixels get sent over a relatively straitened Internet connection and processed by a relatively limited home computer. (Those broadband, video and processor requirements aren’t there for nothing, folks.) A bit over my non-technical head, but worth a read — it’s by Avi Bar Ze’ev, one of the early developers of the program (when it was still Keyhole Viewer). Via Ogle Earth.
