The Walking Access Commission has made its mapping system more accessible.
The commission began developing the mapping system about two years ago, following the debate over access to waterways and other outdoor resources.
Recreational groups and landowners asked for a system that could clearly identify publicly accessible and privately owned land.
The online mapping system now covers most of the country, using basic and topographical maps and aerial photography.
Commission chief executive Mark Neeson says the latest enhancements include making it available on mobile phones.
He says the commission has improved the map's functionality and introduced a system in which other organisations can contribute information.
