Inventory Management

The Inventory Management group is responsible for maintaining Oklahoma's Linear Referencing System (LRS) on which roadway information in the state is aggregated. This roadway database structure includes state, county, and local databases, and the line-work and geometry associated with that data. This group is responsible for providing numerous mileage and network reports for state agencies, federal agencies, and the public.

Mapping & Analytics

The Mapping & Analytics group is responsible for the aggregation and management of the Department's geospatial data. Working closely with other ODOT divisions, local government partners, other state agencies, and the general public, this group provides a wide variety of innovative web-based, mobile, digital, and paper map products.

QAQC, Federal Reporting and Special Projects

The QAQC, Federal Reporting and Special Projects group is responsible for handling the federal reporting aspect for most of the roadway data and its characteristics. Additionally, they oversee cross-functional GIS roles across various departments, ensuring seamless integration and data quality. Their responsibilities extend to rigorous QAQC processes for all outgoing GIS data, and they spearhead innovative special projects such as NG911 data preparation tools and GIS AI initiatives.
