Are you interested in discovering how high your destination is above sea level? Here's how you can do that on Google Maps on Android, iPhone, and in a browser.

A cool free tool creates a heat map of your Google Maps movement data in no time at all. You can immediately see where you spend most of your time and where you rarely go.
