Parcel Data on the Desktop

Terrain Navigator Pro now contains the option to show parcel boundaries* on the desktop as part of a yearly parcel data subscription. Once downloaded to the desktop, parcels can be searched and shown on the desktop without an Internet connection.

The yearly parcel data subscription includes private land ownership details such as:

  • Private land boundaries polygons
  • The landowner's name and address*
  • Assessor's parcel number (APN)

*Private land boundaries should not be considered a legal survey and should only be used for informational purposes. Private land ownership details and boundaries not available in all cities and towns.

Coverage Availability

Note: Coverage as of January 2021 for TNP on the PC platform; TNP Mobile App (Android/iOS) coverage is slightly reduced. Partial coverage means 25% - 75% of the parcels include boundaries and owner information for a specific county. Counties in white have either no data or less than 25% parcel coverage.
