COH ADDRESS INFO THIESSEN POLYGON
This layer consists of Thiessen polygons derived from the COH_ADDRESS_INFO point dataset and is used by the Houston 311 CRIS system to support address verification.
This address Thiessen polygon layer provides a spatial framework for returning city service information for any given XY coordinate pair. Each polygon represents a defined address service area and is attributed with the corresponding operational, administrative, and jurisdictional data. When a coordinate is queried, the system identifies the polygon containing that location and returns the associated city service information, enabling efficient spatial lookup and integration with enterprise applications.
This layer is updated on a monthly maintenance cycle, with the most recent update completed on August 4, 2026.
