N C R S T Tri-states #13 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

N C R S T Tri-states #14 Road Centerline Extraction  Find pixels that represent road … hyperspectral library  Detect linear patterns, form centerlines  Attach legacy attributes  Compare costs and benefits

Easy Street  New neighborhood  Little or no foliage overhang  Vehicles in garage/driveway

Not so easy  Repairs and surface coats  Paint stripes  Shadows  Parked vehicles  Foliage overhangs

N C R S T Tri-states #19 3-step hyperspectral process MESMAQ-treeVectorize Additional steps: clean, revisit, conflate
