Environment Minister Mark Speakman said NSW National Parks and Wildlife Service had also mapped the Blue Mountains and Yuraygir National Parks, meaning there were now 25 parks across the state with Google Street View.

Barwon State MP Kevin Humphries said the partnership meant more than 1100 kilometres of national parks tracks, roads and waterways were accessible from computers and mobile phones right across the world.

"The panoramic views allow park visitors to research tracks and plan their hikes, while hikers who aren't able to physically get to a section of a national park can now see lookouts, valleys and gorges via Google Street View," Mr Humphries said.

"Some sections of parks with delicate ecosystems that are closed off to the public have also been carefully mapped, opening up new ways to have an interesting park experience."

A team of two trekkers walked hundreds of kilometres mapping out a park with a 19-kilogram backpack that creates a 360-degree photo by using 15 cameras, taking photos every three seconds.

Other sections accessible by road are mapped using specially modified vehicles or boats.

Google technicians then receive the images and create high resolution three-dimensional images for every step of the park that has been mapped.

Mr Humphries said NPWS was the first Australian organisation to partner with Google as part of the Trekker Loan Program and was eager to map more parks.

Program Manager for Google Earth Outreach, Karin Tuxen-Bettman hoped the new Street View imagery of the Blue Mountains and other NSW national parks would inspire explorers from Australia and around the world to take an active interest in visiting these parks.

"By loaning Trekker equipment to organisations like NPWS, we can capture images from new locations more quickly, and share more of Australia's beautiful landscapes with the world," Ms Tuxen-Bettman said.

The Street View imagery will be available to the public via the NSW National Parks website and Google Maps as the imagery goes live today.
