2 Discussion Topics Multispectral and Temporal Concepts Terrain –Corridor Planning –Failures –Deformations Roads –Updates & Maintenance –Safety & Incident Management –Hazardous Materials Transport Airports National Consortium for Remote Sensing in Transportation Security, Safety, Hazards, and Disasters

3 Increasing Complexity Local Inventory Single Source Data Simple Identification Manual Analysis Photographs Analog Recording Cameras Balloons Global Surveys Multiple Source Data Complex Problem Solving Machine Assisted Analysis Image & Non-image Data Digital Recording Electronic Sensor Systems Satellites National Consortium for Remote Sensing in Transportation Security, Safety, Hazards, and Disasters Concepts

4 Wavelength, µm R Each pixel has an associated, continuous spectrum that can be used to identify the surface materials. Images taken simultaneously (e.g., in 200 or more spectral bands) inherently registered The Imaging Spectrometry Concept National Consortium for Remote Sensing in Transportation Security, Safety, Hazards, and Disasters Concepts

5 Mapping Monitoring Modeling Other Image Data Legal Economic Social Public Health Topography Sediment Hydrology Utilities Natural Resources Measurement ProblemInformation Decision Action Database Manipulation & Analysis Decision Making Process National Consortium for Remote Sensing in Transportation Security, Safety, Hazards, and Disasters Concepts

6 T+n T+1 T Measurement T N+1 TNTN T+1 T -M Modeling Information analysis for management decision making Measurement, Mapping, Modeling, and Management T+n T+1 T Mapping Management requires constant refreshment of information obtained from measurement, mapping, and modeling. Time provides the means for making static data and information more dynamic. Outputs are more easily visualized in time and space when temporal and spectral attributes are fused.

11 Very near-term prime-time technology. Successfully demonstrated in multiple states. Promises to help bring meaningful streamlining to various NEPA processes. Helps preserve the intent of NEPA to consider all alternatives. Needs to be pilot deployed and applications taken to production mode to allow delivery of finished information products rather than raw data.
