Information Sources
E-mail survey of state DOT GIS managers• 41 State DOTs (and PR) responded in 2005
Significant revision to survey questions
Several new questions added:• Certification of GIS staff• Other geo-data maintained by agency• Maintenance of milepost markers• Greatest benefits & costs of GIS technology

GIS Staffing & Contracting
Slight increase reported in GIS core staffing (Average 7.4 per agency).
GIS certification is not important factor in hiring/advancement of GIS staff.
DOTs outsource about 39% of GIS work.
Average GIS contract budget is about $325,000 per year per agency

GIS Activities: Summary
Web-based applications continue to be major activity areas.Enterprise data integration expanding to include imagery, CAD, and GPS.Increasing emphasis on integrating business systems, not just data.End user applications growing, but not high priority for GIS core staff.
