Good news! :) Bill Kilday, a founder at Keyhole, wrote a book about Keyhole, Where 2, and Google Earth and Maps: "Never Lost Again: The Google Mapping Revolution That Sparked New Industries and Augmented Our Reality". It's not very technical, but it has a lot of interesting history about the products' development and internal Google politics.
Great read! I recently read Bill Kilday’s book: Never lost again[1] which is a fantastic read if you want to learn more about the pre-google-maps and google earth days.
For anyone interested in mapping technology, check out the book "Never Lost Again: The Google Mapping Revolution That Sparked New Industries and Augmented Our Reality". Written by one of the founders of Keyhole, the CIA-funded (In-Q-Tel) company that created the technology that became Google Earth, the book describes the creation of Google Maps, Google Earth, and the political machinations of different Google departments vying to own "geo".
If you're interested in mapping technology and the history of Google Maps (Keyhole) in particular, check out Bill Kilday's book "Never Lost Again: The Google Mapping Revolution That Sparked New Industries and Augmented Our Reality". Kilday was a founder at Keyhole, the startup acquired by Google to become Google Earth.
