Description: A polygon of the extent of all road and parking area surfaces used primarily by automobiles in Yosemite National Park. Does not include paved pullouts and small parking areas along roads.This dataset was initially derived form the park's CAD data that includes survey work of all infrastructure. Has since been modified to better align with road center lines and parking lots to create an accurate representation of the road surface in the park. Field includes a Merced River Plan Alternative 5 that was the selected action for that area.
