A Summary of State DOT GIS Activities Presented at the 2005 AASHTO GIS-T Symposium Lincoln, NE
Information Sources 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
2005 Survey Responses
GIS Deployment in the DOT
Location of GIS Unit
GIS Staff Time Allocation
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
