The Oklahoma County Assessor's Office, responsible for managing over 325,000 parcels worth $90 billion, embarked on a transformative journey to streamline workflows and enhance public access to property information. Leveraging GIS technology, they developed a comprehensive system to map and catalog parcels, providing historical data and valuations to property owners and stakeholders. This initiative not only modernized internal processes but also facilitated informed decision-making across various county departments, from road maintenance to law enforcement.
