Google now offers you a simple application that informs you by email each time we update the satellite and aerial imagery in your area of interest. Follow Your World is a free service that allows you to enter the lat/long of a location along with your email address. Whenever any imagery is updated for that location, an email alert will be sent. Our surroundings are constantly changing, so it's no surprise that Google Earth and Google Maps users often request the most up-to-date satellite and aerial imagery. While Google can't necessarily update the world's imagery in real-time, they can let you know when they do update this imagery. In just three easy steps, you can add points such as your hometown, your college, or just about any place on the Earth. Step 1. Find a location. Search for the area by entering the name of a country, state, city, or a specific address. You can also enter the exact latitude/longitude of the location. Click Search
