Linear transportation features for the Lake Tahoe Basin derived from the August 2010 LiDAR collect. And summer 2010 WorldView-2 imagery. Features were extracted through an automated processes using a proprietary Object-Based Image Analysis (OBIA) system than manually reviewed and corrected at a scale of 1:1,200. The lines have both a Feature Type (FType) and a Surface Type (SType) code associated with them.<\/SPAN><\/P>

The Feature Types (FType) are:<\/SPAN><\/P>

  • 1 = Road<\/SPAN><\/P><\/LI>

  • 3 = Trail<\/SPAN><\/P><\/LI>

  • 4 = Building<\/SPAN><\/P><\/LI>

  • 5 = Other<\/SPAN><\/P><\/LI><\/UL>

    Note: FType = 2 (Driveways) is not used for this layer.<\/SPAN><\/P>

    The surface types (SType) are:<\/SPAN><\/P>
