Nasa has created Mars Trek to mark the third anniversary of the rover landing on Mars.
It allows people to see for themselves some of the features of the red planet using information gathered by Nasa over the past 50 years.
A team from Nasa is also using the interactive map to look at possible landing sites for future missions.

Crowds lined the route of the 24-hour torch relay which began in Stoke Mandeville on Tuesday night.
The relay ran more than two hours late but reduced breaks made up time.
A splinter flame was taken to the Stadium in case the delays were not overcome but the opening ceremony ran late and the flame made it on time.
A late-finishing ceremony in Stoke Mandeville and the time required for multiple exchanges of the flame between team members were blamed for the timing slipping throughout the relay.
Organisers Locog cut down on breaks and reduced the number of photo opportunities and a late-running opening ceremony meant the the flame was used to light the cauldron in the Olympic Stadium.
Crowds gathered in the market square in Aylesbury, Buckinghamshire, to watch the start of the relay and thousands more turned out overnight along the route to cheer on the torchbearers.
After arriving in London, the flame, which is being carried by 580 torchbearers, was taken up the steps to Britain's first traditional Hindu temple, the Shri Swaminarayan Mandir temple in Brent, where a torch was lit at about 08:30 BST.
Barry Gardiner, MP for Brent, took part in a ceremony which involved pulling apart string made up of different threads and colours to "allow" the Paralympic torch through.
He said: "It was a very special moment. We have been waiting since 6.30am and the thrill and excitement is just fantastic. I don't think there has ever been a setting like this, for an Olympic or Paralympic flame."

The Paralympic Games are being talked-up a lot this year.
Channel 4 has put a lot of marketing and production effort into bringing the Games to a wider audience than before, with over 500 hours promised to UK viewers.
Important figures in sport and politics have stepped up to tell us that the Games will "dazzle" and "inspire". Seb Coe said those watching the sports would be "blown away".
But will we all want to see TV coverage of the 2014 Winter Paralympics in Sochi? Or the next summer Games at Rio 2016? And is there a worldwide clamour to push this recently unearthed disability agenda across the globe, or are we just feeling it more because it's our Games?
The significance of London 2012 Paralympics will be in the legacy and it might take a little while before we can fully appreciate the impact of that.

In Maida Vale a team of torchbearers was cheered by crowds as the flame was carried over the Abbey Road crossing, made famous by The Beatles album cover.
At London Zoo in Regent's Park the flame was held aloft in the penguin enclosure by torchbearers Adam Hollick, John Craig, Fiona Forsyth, Charlie Humphrys and Aruna Mahtani.
All members of the team, who were previously unemployed and have disabilities including spinal cord injury, blindness and impaired mental health, have trained and qualified as gym fitness instructors.
Former boxer Michael Watson, wheelchair racer Dame Tanni Grey Thompson and Paralympic swimmer Chris Holmes were in the team who carried the flame along Regent Street and through Piccadilly Circus.
Torchbearer Edward Parker co-founded the Walking With The Wounded charity, which raises money to support injured servicemen and women.
He was nominated to carry the flame by Prince Harry.
The 46-year-old from Norwich was joined by fellow nominees, his nephew Harry Parker, 29, who lost both his legs in Afghanistan and Captain David Wiseman, 29, who was shot while fighting the Taliban.
The charity's co-founder Simon Daglish, 46, and his son Felix Daglish, who has cerebral palsy also joined the team.
Edward Parker said carrying the flame was "a very special thing to be able to do. I felt a bit humbled by the whole thing. It was an amazing feeling."
He added: "It was great going past Horse Guards [Parade] and the Ministry of Defence. It means a lot to have their support."
Nasa has created a new interactive web site to allow people to explore the surface of Mars just like the Curiosity rover is doing.
