One of the biggest challenges facing the insurance industry is the sufficient assessment of the risk profile of real estate properties.

Underwriters rely heavily on accurate and up-to-date data to help adequately assess the risk and corresponding cost of insuring a particular property.

Reliable and accurate parcel and boundary data can help insurance providers gain better insights into properties and eliminate inaccurate quotes that waste time, money, and, ultimately, frustrate customers.


What is parcel and boundary data?

Parcel and boundary data represent the basics of any property and include nearly everything you need to know about the land that makes up the property.

A parcel or boundary represents the boundaries, borders, or coordinates of a plot of land or whole property rather than the specific units within the property.


Using Quantum Geographic Information System (QGIS)* shown above, counties are able to map boundaries on a map that show every property or plot of land in a given area.

And with the constant development of land and continuous construction of buildings, boundaries can be split, modified, merged, or otherwise changed so frequently that existing boundary lines can be used to track proposed and future changes from governing authorities to better serve clients.

*Please note, mapping service and integration is not provided by Estated, only raw boundary data points. The boundary applies to the whole property, not to units within the property.

Parcel details, provided by the assessor, can include the following fields:

  • fips_code—Federal Information Processing Series (FIPS) are unique numeric codes assigned US states and counties;
  • depth_ft—the depth of the parcel measured in feet;
  • frontage_ft—the frontage of the parcel measured in feet;
  • area_sq_ft—the total area of the parcel measured in square feet;
  • area_acres—the total area of the parcel measured in acres;
  • land_use_type/category—the general land use category for the property;
  • zoning—unique designation of zoning made by the city;
  • building_count—count of all buildings on the property;
  • lot_code/number—indicates properties with multiple or partial lots;
  • subdivision—name of the subdivision or tract in which the property is located;
  • municipality—jurisdiction in which the property is located.

While boundary (coordinates along a parcel's boundary at specific points) can include the following fields:

  • wkt—the well-known text representation of the boundary as a geometric multi-polygon for use in geographic information system (GIS) software.
  • geojson—a standard format designed for representing geophysical features using longitude, latitude, and elevation.

Importance of property data for insurers


In combination with the rest of Estated's schema of hundreds of different data points, parcel and boundary data can provide the most accurate and complete picture of a particular property or set of properties, which then becomes a very powerful tool for a variety of industries including insurance.

Leading insurance providers, insurtechs, and underwriters can use property data to help assess the hazard and risks associated with insuring a particular property.


For example, using geographic parcel and boundary data, an insurance company can easily determine if a property is located near a flood plain or situated in an area more susceptible to catastrophes such as tornado alley or a wildfire zone, and thus calculate their insurance premiums more accurately.
