RESEARCH PROJECTS Tri-states 2001 -08 -14 #

DOT Priorities — 1 ¨ Accurate centerline maps consistently identified as a high priority, by photogrammetry and IT staff in DOTs ¨ Critical resource for • ITS, EMS • Highway management: integration of linear referenced archives with GPS Tri-states 2001 -08 -14 # NCRST

Road Centerline Extraction Find pixels that represent road … hyperspectral library ¨ Detect linear patterns, form centerlines ¨ Attach legacy attributes ¨ Compare costs and benefits ¨ Tri-states 2001 -08 -14 # NCRST

Easy Street ¨ New neighborhood ¨ Little or no foliage overhang ¨ Vehicles in garage/driveway Tri-states 2001 -08 -14 #

Not so easy ¨ Repairs and surface coats ¨ Paint stripes ¨ Shadows ¨ Parked vehicles ¨ Foliage overhangs Tri-states 2001 -08 -14 #
