Short summary
This study uses geographic information systems (GIS) to determine which landforms are most visible to motorists from the highways of the northwestern US. Using an elevation dataset, a computer determined the area visible from sample points taken at 1 km intervals along the highway network. Highly visible mountains, ridges, and valleys were identified and mapped. These methods can be used to identify scenic byways, inform infrastructure development, and improve maps and navigation apps.
