Impact of Instant Image Access on a Regional Database for Transportation Planning 6 Met with transportation planners at various levels Conducted 15 briefings & 3 technical exchange meetings Defined demonstration study area for live software demonstration Collected digital imagery and GIS vector data Completed oral presentation for Transportation planners Developed demo MicroStation and Viecon Publisher software Presented Demonstration of ‘Instant Imagery Access’ (IIA) Completed Implementation plan for IIA Contributed to NRSTC publications Presented project at TRB 2001 and GIS-T 2002 conferences Submitted quarterly reports Project Status/Accomplishments

Impact of Instant Image Access on a Regional Database for Transportation Planning 7 Summarized from Technical Exchange Meetings: Facilitate image use by making image processing steps transparent to user Diverse Imagery is important for project decision making and presentations Data integrity is required between planning company and other Federal and State agencies Image data must be up-to-date for land use and change detection analysis Sensitive areas (parks, churches, schools, etc) must be detected early in the planning stage Images at different scales are needed Freeway and corridor studies, and rail station site assessments are common It is necessary to have readily available metadata including source reference It was suggested that ‘Instant Imagery Access’ be used by universities and public schools Transportation Planning Needs
