N C R S T STELLA/STAR 2002-01-17 #2 Why this engineering stuff? Methodological research DOT as customer: GI-science brings operational efficiencies Academics (social scientists) as end-users: facilitates DOT data, e.g. access, safety Hands across the sea: idea exchange

10
N C R S T STELLA/STAR 2002-01-17 #10 Early Thinking RS is not a monolithic solution; many types of imagery many approaches No centerline solution is the “right” answer for all needs; each addresses a niche scale rural vs urban Initial plan: validate RS with GPS
11
N C R S T STELLA/STAR 2002-01-17 #11 Imagery Resources AVIRIS Soft copy photogrammetry Landsat TM Spatial resolution Spectral resolution IKONOS Material classification Edge detection
13
N C R S T STELLA/STAR 2002-01-17 #13 Lessons Learnt There are many approaches No RS centerline solution is the answer to all our needs; each addresses a niche Manual process with some automation, or largely automated process with some user intervention

N C R S T STELLA/STAR 2002-01-17 #14 The GPS Challenge
15
N C R S T STELLA/STAR 2002-01-17 #15 GPS Results — lane resolution

N C R S T STELLA/STAR 2002-01-17 #18 CLEM2001 August 2001 meeting of specialists Remote sensing: soft copy, edge detection, multispectral, hyperspectral … GPS ± 10m GPS+gyro ± 10 cm Video logging ITS
19
N C R S T STELLA/STAR 2002-01-17 #19 Centerlines from RS — conclusion RS not a fully automated solution … yet Augments other methods (e.g. GPS) effectively, esp. visual verification Good for small areas: 1:5K soft-copy photogrammetry Good for large areas, 1:50K to 1:100K … global databases, sustainable policy, etc Research is promising, worth pursuing
