The Geographic Information Systems (GIS) team champions the use of GIS technology throughout the department, represents the DOT's interests at the state level, develops and maintains the state's geographically referenced road network, and creates applications for collecting and viewing data (see graphics below). GIS staff accesses spatial data related to all transportation activities and develops products used to assist the DOT in decision-making processes. Examples of GIS products include iPad applications for collecting field data, interactive mapping applications, story map applications, and specialized maps.
