A Summary of State DOT GIS Activities
Presented at the 2004 AASHTO GIS-T Symposium Rapid City, SD
Information Sources
E-mail survey of state DOT GIS managers
• All 51 State DOTs (and DC) responded in 2004 • First time 100 % response
Results compared with prior year surveys Two new questions added:
• Use of spatial data manager middleware • Questions you would like to see in future surveys

GIS Organization: Summary
All but one State DOT have a recognized GIS unit. Continuing trend to locate GIS core staff in Information Services. GIS deployment strategies split between core GIS unit and enterprise GIS GIS budgets in many states impacted somewhat by State fiscal cutbacks.
