Vegetation - Proposed Tehachapi Pass High Speed Rail Corridor [ds1328]
The Geographical Information Center (GIC) at California State University, Chico, completed a vegetation map of the Proposed Tehachapi Pass High-Speed Rail Corridor (HSRC), covering 199,493 acres. The project was funded by the Strategic Growth Council to support routing and mitigation planning for the high-speed rail system. The map was produced using heads-up digitizing based on 2012 National Agricultural Imagery Program (NAIP) imagery. The minimum mapping unit (MMU) is one acre for most vegetation types, with a smaller MMU for wetlands. Although the primary purpose of the map is to document vegetation communities, it provides additional structural data such as herbaceous, shrub, and tree cover, and information about the level of disturbance within the vegetation stand. The overall accuracy of the map exceeded the state standard of 80 percent.
