What Is Property Boundary & Parcel Data?
Property boundary and parcel data defines the spatial and legal boundaries of individual plots of land, including lot lines, easements, and parcel dimensions with precise geographic coordinates. This data represents the boundaries of a plot of land or specific property and includes attributes such as unique parcel identifiers, FIPS codes, APN numbers, zoning information, lot size, land use classifications, and centroid latitude/longitude coordinates. Parcel data serves as the spatial backbone of real estate analytics, enabling accurate geospatial mapping and comparison across neighborhoods, developments, and municipalities. The data is essential for title companies, proptech platforms, real estate valuation systems, and insurers who require precise parcel geometry to support underwriting decisions, AI-powered valuations, and risk assessments.

Pricing depends on the proposed terms
We do not have a verified, comparable price for your dataset. Consider the permitted uses, license term, exclusivity, provenance, coverage and quality. A seller asking price is a proposal, not an appraisal or guaranteed sale. Compare prices only when the source, date, currency, unit and license scope are known.

FAQ
Common questions.questions.
What attributes are included in parcel boundary data?
Standard parcel data includes unique parcel identifiers, FIPS codes, APN numbers, Census codes (state, county, tract, block group, block), centroid latitude/longitude coordinates, elevation, property address, city, state, postal code, lot size, zoning classification, land use designation, and recent valuation/sale information.
How is parcel data used in insurance underwriting?
Insurers use parcel boundary data to assess property risk profiles by identifying properties in high-risk areas such as flood zones and other hazard-prone locations. This enables more accurate underwriting decisions and helps determine appropriate insurance premiums based on geographic risk factors.
Why is parcel data important for real estate AI and valuation?
Parcel data serves as the spatial backbone of real estate analytics, providing precise geospatial accuracy and enabling AI models to aggregate and compare properties across neighborhoods, developments, and municipalities. When combined with AVM and MLS data, it produces more accurate, granular property valuations and market intelligence.
What data quality standards do major parcel data providers follow?
Leading providers like ATTOM employ rigorous enterprise data management programs involving over 20 validation steps including property address standardization, owner name parsing, multi-source data fusion, and consistent ID matching to ensure data accuracy and consistency across their entire parcel database.
