Accurate, Current Geographic Data for the U.S.

Understanding the relationship between a property's physical location and surrounding geographic features is critical to many business applications. Our suite of Geographic Information System (GIS) databases integrates into leading mapping and visualization applications to provide the geographic insights you need to make intelligent business decisions.

Our geospatial databases are licensed in Shapefile format and can be used with our software products or your GIS system.

Up-to-Date Municipal and Township Data

We are one of the few solution providers with our own municipal boundary data files. We have a staff dedicated to the ongoing research involved in tracking annexation and de-annexation changes, allowing us to continuously maintain the database for accurate results. Containing state, county and township level information for all 50 U.S. states, the township database consists of continuous polygonal townships with boundaries aligned to NAVTEQ county boundary data.

National Elevation, Slope and Aspect Data

We provide a national elevation, slope and aspect database at a 10-meter grid granularity. Understanding the elevation and slope, as well as the direction the slope faces (aspect), is essential to understanding the placement and underlying asset risk. We enhance our parcel and property data by applying regular updates, utilizing public and private data and proprietary algorithms to calculate the slope and aspect. As a result, we give you a complete picture of your land-based resources.

Quarterly Updated Fire Station Data

Knowing where a homeowner's property is in relation to a fire station helps insurance companies determine the property’s fire ranking. Our fire stations and response areas database contains fire station locations and fire response areas incorporated into a standardized, national, digital database that we update quarterly.

When compiling federal, state, local and commercial sources, we verify fire station locations using our parcel-level geocoding and spatial technologies, highly accurate road network data, high-resolution aerial photography, on-site visits and personal contact surveys. We base our fire response areas on county and municipal boundaries, as well as fire district boundaries gathered directly from local sources in each state.

Our database also provides such valuable information as the type of district (indicating whether a station is full-time, voluntary or both), the distance from the nearest station to a property and the geographic coordinates of each fire station.
