A Summary of State DOT GIS Activities Presented at the 2000 AASHTO GIS-T Symposium Minneapolis, MN
Information Sources E-mail survey of state DOT GIS managers 49 State DOTs responded in 2000 Results compared with 1996-1999 surveys Additional insights from informal discussions with DOTs and state data sharing partners
Stage of Development Operational Implementation Pilot Preliminary Planning 2000 1999 1998 1997 1996 No GIS Activity 0 5 10 15 20 25 30 35
Location of GIS Unit Multiple Locations Planning Information Mgmt. Mapping/Cart. Unknown 2000 1999 1998 1997 1996 0 5 10 15 20

GIS Organizational Fit Increasing numbers of DOTs with GIS units in more than one organizational division Often, shared responsibilities between planning and information services Trend also reflects deployment of end-user GIS tools throughout the DOT
GIS Staff Size 20 or More 10 to 19 6 to 9 2000 1999 1998 1997 1996 5 or Less No Staff / Not Reporting 0 5 10 15 20 25
GIS Staff Position Classifications Programmer GIS Professional Planner Analyst Engineer Other 0 5 10 15 20 25
GIS Users in DOTs 1 to 9 14% No Report 10% Over 100 28% 10 to 49 40% 50 to 99 8%
GIS Staff & Users Average GIS staff increased from 7.1 to 8.4 since 1996. More DOTs are able to hire GIS professionals specifically: GIS is still viewed largely as a programming position Many DOTs support 10 or more GIS end-users per GIS staff
GIS Budgets Over $1,000,000 $500,001 to $1,000,000 $100,000 to $500,000 Under $100,000 2000 1999 1998 1997 1996 No Dedicated Budget / No Report 0 5 10 15 20 25 30 35

Hardware & Software Continuing trend toward Windows NT operating system. Multiple GIS software used within the DOT. Growth in niche market software for specialized GIS-T applications User friendly desktop GIS used for departmentwide deployment
Base Map Scales 1:12K 1:24K 1:100K Other Scales / Multiple Scales No Base Map / No Report 2000 1999 1998 1997 1996 0 5 10 15 20 25 30
Spatial Databases DOTs generally settling on either 1:24K or 1:100K basemaps. Nearly 2/3 of states using 1:24K scale or larger Many DOTs participate in statewide GIS coordinating councils for data sharing. Currently 30 state GIS councils are officially recognized NSDI cooperating partners. Several states have established statewide GIS data centers.

GIS-T Research Priorities Document and disseminate GIS-T applications from other state DOTs. Develop improved methods for conflating spatial data. Establish and maintain a directory of GIS-T contacts at state DOTs. Improve database interoperability between commercial GIS packages.
GIS-T Research Priorities Develop improved GIS-T training for DOT managers and technicians. Identify GIS-T skills required in state DOTs and create standard GIS position descriptions. Develop a library of GIS-T literature accessible via the Internet. Develop tools to better integrate GIS with other transportation models.
GIS-T Research Priorities Develop improved LRS functionality in GIS software. Establish spatial data standards to facilitate data sharing among agencies. Develop improved procedures for using GPS measurements to improve basemap accuracy and locational references.
