A Summary of State DOT GIS Activities Presented at the 2004 AASHTO GIS-T Symposium Rapid City, SD
Information Sources 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 Deployment in the DOT
Location of GIS Unit
GIS Budgets
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.
GIS Core Unit Staffing
GIS End Users
GIS Staff Classifications
GIS Staff & Users: Summary Nearly 40% of State DOTs reported decreases in their GIS core staff Continuing growth in GIS end users in most State DOTs GIS core staff skills migrating toward IT data management and programming
GIS Software in State DOTs
Current GIS Software Mix
DBMS Software
GIS Software: Summary All State DOTs use Windows for some GIS applications Some increase in use of UNIX Increased use of multiple GIS software packages and vendors DBMS software dominated by Oracle and Access, but strong growth of SQL
