Rebecca Davis, Sr. Project Manager, 11 years of GIS experience focused on state and local government data from parcels to natural resources to utility systems to transportation.
Carson Vallino, Project Manager, 9 years of GIS experience working with local governments supporting parcel and address data maintenance.
Municipalities and organizations often maintain address information across multiple systems and departments, including GIS, permitting, public safety, utilities, planning, and property records. Over time, these datasets can evolve independently, resulting in duplicate addresses, conflicting formats, missing records, and disconnected workflows. These challenges can impact everything from permitting and public safety response to geocoding accuracy and system integrations.
This is an informative webinar recording exploring how organizations can develop a Master Address Table (MAT), an authoritative repository that unifies address information from multiple sources into a standardized, reliable, and maintainable dataset. Municipal clients have successfully used MATs to integrate permitting platforms, improve data quality, and streamline workflows.
During this session, the presenters discuss:
- What a Master Address Table is and why it serves as the foundation for modern GIS and business system integrations.
- Approaches for combining assessor records, GIS address points, permitting systems, utility data, and other address repositories into a single authoritative dataset.
- Techniques for standardizing address formats, eliminating duplicates, resolving data conflicts, and supporting complex addressing scenarios such as apartments and condos.
- The importance of governance, workflows, and change management in maintaining accurate address information over time.
Whether you are a GIS professional, assessor, planner, permit administrator, or IT leader, this webinar recording will provide practical insights into creating and maintaining an address framework that improves data quality, supports municipal operations, and serves as a trusted source for the entire organization.
