When Google acquired Keyhole — the tool that would become Google Earth — in 2004, the company believed it would become the ultimate video game. Google thought travelers could peruse potential vacation destinations and movie makers could use the detailed satellite imagery as a backdrop in films.

But Google had no idea the virtual globe and geographic data program had the potential to become a tool for grassroots mobilization, environmental protection and disaster response.

Today, through the Google Earth Outreach program, the tool has become a vital instrument for non-profits and public benefit organizations to visually tell their stories. For example, The World Wildlife Fund is using Google Earth to protect Sumatran tiger cubs, and relief workers used the tool for crisis response after Japan's 2011 earthquake. Meanwhile, The HALO Trust uses the tool to locate and remove landmines, and Brazil's Surui tribe uses Google Earth to map its home in the Amazon Rainforest.

The Google Earth Outreach team has created a tool kit of tutorials for organizations looking to create their own storytelling maps. You can add points, lines and polygons and embed YouTube videos to your annotated map.

Google Earth Outreach awards non-profits with Developer Grants to help them use mapping technologies to best tell their stories. Previous grant recipients include Water For People, which developed a mapping app to support sanitation-related businesses in African cities, and International Rivers, which created a video showing why dams aren't the best response to climate change.

Uses of Google Earth That Have Made Positive Impacts on the World

How It All Got Started

A few weeks before Google Earth Outreach Engineering Manager Rebecca Moore got her start at Google in 2005, she received an "inscrutable" notice about tree logging in her community in the Santa Cruz Mountains, with a confusing black-and-white map of the work to be done. Moore took to Keyhole, the tool that would become Google Earth, to begin plotting out the work described in the notice in a more digestible, digital manner.

"It was really striking how much more you could understand and I presented it to the community," Moore told Mashable, describing the origins of a group she belongs to Neighbors Against Irresponsible Logging (NAIL). "As I remapped elements of that logging notice, that's where I said there's really something here."

Moore's Google Earth map convinced her community to come up with a better alternative than what had initially been proposed.

On Moore's second day at Google, Hurricane Katrina hit New Orleans. The U.S. government asked Google to publish near real time imagery, such as postings of family whereabouts, on Google Earth, which would be the fastest way to reach the emergency medical responders. Google CEO Eric Schmidt spoke with the engineers, Moore recalls, and said, "Whatever you're working on right now isn't important compared to saving lives in New Orleans."

Through Google's mapping, the first responders could see where people were stuck and could then decide if boats or helicopters were the best rescue tools in specific cases. The Coast Guard later told the Google team that its technical support helped save 4,000 lives.

"Non-profits all over the world started writing to me and we had a feeling it could be used for all sorts of environmental projects," Moore says.

When Google Earth Outreach officially launched in June 2007, Keyhole founder John Hanke saw the non-profit implementations of Google Earth and said the product's girth was much more significant than he had realized.
