Landscape Condition weighs the relative influence of different types of human footprints based on factors such as permanence and the nature of the activity. Permanent human modification is weighted the highest, while temporary use, like snow roads and snowmachine trails, receives less weight. Intensive land uses like mining are also weighted higher than less intensive land uses like hunting or trapping cabins. These weights are summed across the landscape and coalesced into a single surface identifying how impacted a given area is due to human modification.
