The NSW Government has teamed up with Google to go off-road and map some of NSW's most stunning national parks.

The partnership involves NSW National Parks and Wildlife staff wearing a special backpack equipped with the Street View camera system, hiking through various landscapes and capturing 360 degree imagery to map the walks.

Environment Minister Rob Stokes today joined one of the first mapping exercises, in Sydney Harbour National Park.

"Over the next few months 16 parks including the Blue Mountains and the world's second oldest national park, Royal National Park in Sydney's south, will be mapped by Google and NPWS,” Rob Stokes said.

"The imagery will be stitched into panoramic digital renderings of these walks and then published on Google's Street View gallery of the world which will be unveiled at the IUCN World Parks Congress hosted in Sydney this November.

"By using the Google Street View Trekker, we can make our parks even more accessible to the public.

"If you've ever dreamed of going to one of our spectacular parks, or are planning a trip, the Street View imagery will give you a way to explore, plan you adventure and learn about the area beforehand.

"There's nothing quite like looking at the amazing views across the Pacific Ocean towards North and South Head or gazing across the Blue Mountains, but now everyone will be able to gain an appreciation of the landscapes within our state."

Megan Boundey, Product Manager for Google Maps in Australia, said: “We're thrilled to be working with NSW National Parks as the first partner in our pilot Trekker Loan Program for Australia. By loaning the equipment to organisations around the world, we can capture images from new locations more quickly, and improve our ability share more of Australia's beautiful landscapes with the world.”

NSW National Parks is the first organisation in Australia to be part of the Google Trekker loan program, which sees third party organisations, NGO's and not-for-profits apply to borrow Trekker to collect imagery of hard to reach places and help map the world.
