Sarah Parcak: A hundred years ago, archaeology was for the rich,
fifty years ago it was for men.
But we are expanding it to the world.
I wish for us to discover
the millions of unknown archaeological sites around the world.
By creating a 21st-century army of global explorers,
we'll find and protect the world's hidden heritage.
So how are we going to do this?
[Great Big Story in partnership with TED]
Narrator: They had a big idea to change the world.
But they couldn't do it alone.
(Voices overlapping) So, my wish ... My wish ... I wish ...
And now, here is my wish ...
[Torchbearers]
[Ideas in action]
SP: I am an archaeologist,
and I specialize in using satellite imagery to map ancient landscapes.
The really fun title is space archaeology.
You of course want to record maybe how thick something is,
which you can't measure from space, whether that's soil or snow.
When I won the prize, I had to present this completely crazy wish.
I had to present the case for archaeology to the world.
Why does it matter, so what?
The reality is, there aren't enough of us scientists,
we've got to give more people opportunities to become explorers.
GlobalXplorer is an online crowdsourcing platform
that allows anyone in the world to help map ancient sites
by looking at satellite imagery.
And it's this idea that everyone in the world
can make a contribution to science.
It can be anyone.

Doris Jones: I'm Doris Jones, I'm 90 years old, I live alone
except for my two kitties.
And I need something to do.
I play games, I like sudoku.
And I play mahjong with friends on Friday.
(Music)
And I'm an armchair archaeologist.
Why don't you want to work? Down.
Down, let's work.
SP: Doris is one of our top contributors;
she's a space archaeologist.
She's looked at many, many thousands of tiles.
People like her are just a gift to GlobalXplorer.
DJ: Right now, I'm looking at a tile, but ...
Well, it has a wall, probably for animals.
But it has a number of what look more like trails and roads.
I'll go to the next one.
SP: All you have to do is look at an image and look carefully,
and you see that there could potentially be a new site there.
Doris just has this passion and energy,
an excitement for exploration.
She's able to give back and really contribute in a meaningful way.
(Skype dial tone)
SP: Doris!
DJ: Hi.
SP: I'm actually crying right now, because I'm overwhelmed with emotion.
DJ: Well, thank you.
SP: I just had to see your face and say, "Thank you."
DJ: I really admire what you're doing.
And I really enjoy the program.
SP: When did your love for archaeology and paleontology and science start?
DJ: Well, in the middle 50s my husband and I were in the backyard
digging a garden.
It was late fall, and we were getting ready for next spring.
And I saw a strange-looking white rock on the ground.
I picked it up and he said, "Let me see that."
I showed it to him and he said, "You know what this is?"
I told him I didn't.
He said, "This is a fossil."
And we took out to the creek and started looking for fossils.
From then on, there was no turning back.
SP: That's wonderful.
DJ: So then I collected for years.
And after all those years, of course I've got all those memories.
But that's a type of thing ...
It's not just hunting the fossils but the experiences.
And you just learn and really live and enjoy.
And I think the fun is in the hunt.
You know, it's like ...
Well, like the rainbow --
at the end of the rainbow is a pot of gold.
So GlobalXplorer was kind of my rainbow.
And even at my age
I can continue to hunt for lost civilizations.
SP: I want to tell you about some of the incredible things
that happened as a result of your discoveries.
We're now beginning to take thousands of features
that people like you have found
and we're sharing them with archaeologists who work in Peru.
They're beginning to confirm the things the crowd has found.
So, in other words, the platform works.
Ultimately, this technology is helping us to rewrite our history.
DJ: We need to know our history.
We're all one peoples.
It's all our history, we're all here on this little ball of dirt.
SP: I believe we have barely scratched the surface
in terms of what's left to discover.
And the greatest story ever told
is the story of our shared human journey.
But the only way that we're going to be able to write it
is if we do it together.
