@GMapsPlatform @engadget This is a great development! One of my pet peeves about online maps is now gone; this will really help my students appreciate the correct relative sizes of places on the Earth. Thanks!

@GMapsPlatform Would love to hear that a revised billing policy would allow sites like "thetruesizeof" to return to the educational world. This online tool changed the paradigm of many students in my classes, challenging their misconceptions about how they view other countries.
