The COH_ADDRESS_INFO dataset functions as an extensive master dataset for address points in Houston area. It originates from the SiteAddresses dataset managed by the Planning & Development Department. To enhance this dataset, several geoprocessing tasks were performed, integrating the City\u2019s administrative and service boundaries along with relevant state and local government information. Initially created in 2012 to support the legacy Lagan 311 system for address verification, this dataset has significantly evolved, now encompassing over 80 attribute fields that provide detailed insights into the City of Houston's administrative and service boundaries as well as pertinent data from state and local government entities. ", "summary": "This layer represents Thiessen polygons generated from COH_ADDRESS_INFO point data.
