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
