The Mapping Sheets add-on in Google Drive is pretty darn cool.
Harold Cooper, the man behind extendny.com, has given all of us who’ve ever wanted to have a New York City address a reason to celebrate. This fun little application uses the Google Maps API to extend the Manhattan grid to anywhere in the world. I’m not exactly sure how it works, but I do know that I currently live at the intersection of the the high-500s Avenue and the mid-3,000s Street.
