Development of Nevada Highway Fencing GIS Database
The Nevada Department of Transportation (NDOT) has been installing wildlife fences along interstate/state highways where wildlife-vehicle collisions (WVCs) concern exists. A fencing geographic information system (GIS) dataset can be used to coordinate the locations and construction of new wildlife crossing structures and wildlife fences. A statewide fencing GIS database is also essential for rural highway safety analysis, especially when it is integrated with crash data, wildlife animal migration data, road properties, and existing crossing structure data. The Center for Advanced Transportation Education and Research (CATER) at the University of Nevada, Reno (UNR) developed a Nevada statewide highway fencing database in this project by reviewing multiple data sources such as Google Earth Pro, Google Maps, Google Street View, Bing Maps and the Roadview database of NDOT. The data of crossing structures were also collected from the aerial map pictures and street view pictures when the team extracted the fencing data.
A potentially useful tool for MDT biologists and planners is a database table indicating where highways throughout the state show the potential for co...
