  • Four years ago, here at TED,

  • I announced Planet's Mission 1:

  • to launch a fleet of satellites

  • that would image the entire Earth, every day,

  • and to democratize access to it.

  • The problem we were trying to solve was simple.

  • Satellite imagery you find online is old, typically years old,

  • yet human activity was happening on days and weeks and months,

  • and you can't fix what you can't see.

  • We wanted to give people the tools to see that change and take action.

  • The beautiful Blue Marble image, taken by the Apollo 17 astronauts in 1972

  • had helped humanity become aware that we're on a fragile planet.

  • And we wanted to take it to the next level,

  • to give people the tools to take action, to take care of it.

  • Well, after many Apollo projects of our own,

  • launching the largest fleet of satellites in human history,

  • we have reached our target.

  • Today, Planet images the entire Earth, every single day.

  • Mission accomplished.

  • (Applause)

  • Thank you.

  • It's taken 21 rocket launches --

  • this animation makes it look really simple -- it was not.

  • And we now have over 200 satellites in orbit,

  • downlinking their data to 31 ground stations we built around the planet.

  • In total, we get 1.5 million 29-megapixel images of the Earth down each day.

  • And on any one location of the Earth's surface,

  • we now have on average more than 500 images.

  • A deep stack of data, documenting immense change.

  • And lots of people are using this imagery.

  • Agricultural companies are using it to improve farmers' crop yields.

  • Consumer-mapping companies are using it to improve the maps you find online.

  • Governments are using it for border security

  • or helping with disaster response after floods and fires and earthquakes.

  • And lots of NGOs are using it.

  • So, for tracking and stopping deforestation.

  • Or helping to find the refugees fleeing Myanmar.

  • Or to track all the activities in the ongoing crisis in Syria,

  • holding all sides accountable.

  • And today, I'm pleased to announce Planet stories.

  • Anyone can go online to planet.com

  • open an account and see all of our imagery online.

  • It's a bit like Google Earth, except it's up-to-date imagery,

  • and you can see back through time.

  • You can compare any two days

  • and see the dramatic changes that happen around our planet.

  • Or you can create a time lapse through the 500 images that we have

  • and see that change dramatically over time.

  • And you can share these over social media.

  • It's pretty cool.

  • (Applause)

  • Thank you.

  • We initially created this tool for news journalists,

  • who wanted to get unbiased information about world events.

  • But now we've opened it up for anyone to use,

  • for nonprofit or personal uses.

  • And we hope it will give people the tools to find and see the changes on the planet

  • and take action.

  • OK, so humanity now has this database of information about the planet,

  • changing over time.

  • What's our next mission, what's Mission 2?

  • In short, it's space plus AI.

  • What we're doing with artificial intelligence

  • is finding the objects in all the satellite images.

  • The same AI tools that are used to find cats in videos online

  • can also be used to find information on our pictures.

  • So, imagine if you can say, this is a ship, this is a tree,

  • this is a car, this is a road, this is a building, this is a truck.

  • And if you could do that for all of the millions of images

  • coming down per day,

  • then you basically create a database

  • of all the sizable objects on the planet, every day.

  • And that database is searchable.

  • So that's exactly what we're doing.

  • Here's a prototype, working on our API.

  • This is Beijing.

  • So, imagine if we wanted to count the planes in the airport.

  • We select the airport,

  • and it finds the planes in today's image,

  • and finds the planes in the whole stack of images before it,

  • and then outputs this graph of all the planes in Beijing airport over time.

  • Of course, you could do this for all the airports around the world.

  • And let's look here in the port of Vancouver.

  • So, we would do the same, but this time we would look for vessels.

  • So, we zoom in on Vancouver, we select the area,

  • and we search for ships.

  • And it outputs where all the ships are.

  • Now, imagine how useful this would be to people in coast guards

  • who are trying to track and stop illegal fishing.

  • See, legal fishing vessels

  • transmit their locations using AIS beacons.

  • But we frequently find ships that are not doing that.

  • The pictures don't lie.

  • And so, coast guards could use that

  • and go and find those illegal fishing vessels.

  • And soon we'll add not just ships and planes

  • but all the other objects,

  • and we can output data feeds

  • of those locations of all these objects over time

  • that can be integrated digitally from people's work flows.

  • In time, we could get more sophisticated browsers

  • that people pull in from different sources.

  • But ultimately, I can imagine us abstracting out the imagery entirely

  • and just having a queryable interface to the Earth.

  • Imagine if we could just ask,

  • "Hey, how many houses are there in Pakistan?

  • Give me a plot of that versus time."

  • "How many trees are there in the Amazon

  • and can you tell me the locations of the trees that have been felled

  • between this week and last week?"

  • Wouldn't that be great?

  • Well, that's what we're trying to go towards,

  • and we call it "Queryable Earth."

  • So, Planet's Mission 1 was to image the whole planet every day

  • and make it accessible.

  • Planet's Mission 2 is to index all the objects on the planet over time

  • and make it queryable.

  • Let me leave you with an analogy.

  • Google indexed what's on the internet and made it searchable.

  • Well, we're indexing what's on the Earth and making it searchable.

  • Thank you very much.

  • (Applause)
