Property Tax Mapping Systems

Property tax mapping systems integrate cadastral maps with assessment data (CAMA), enabling jurisdictions to calculate and manage property taxes. They link parcels to attributes such as land use, building characteristics, assessed value, exemptions, and sales histories. GIS provides visualization, spatial analysis (e.g., assessment equity across neighborhoods), and change tracking. Systems must handle appeals workflows, versioning across assessment years, and privacy controls. Interoperability with permitting and building data reduces inconsistencies. Public-facing portals improve transparency by showing assessments and comparables while disclaiming valuation methodologies. Governance includes audit trails, role-based access, and compliance with legislation.
