SFAQ (Selected Frequently Asked Questions)

What is the geocoding accuracy? We generally return two types of geocoding results, Rooftop / Parcel Geocoding and Street Interpolation Geocoding. (The other types as based on postal/zip codes, city/neighborhood names, ip addresses, etc).
  • Rooftop / Parcel Geocoding is the most precise Geocoding methodology because it returns an exact match to a single address point (normally placed at the center of the "roof" of the property/parcel, hence "Rooftop".)
  • Street Interpolation Geocoding works by estimating a location in a known address range, a method also known as address intepolation. The geocoding algorithm matches an address to a street and a specific segment then interpolates the position within that segment. Since this is an approximation, this method is generally less accurate than the "Rooftop" method.
Currently over 40% of the geocoding requests we receive return Rooftop results with Confidence Score = 1.
Interpolated results have a maximum Confidence Score of 0.9.
for Example:
  1. 2525 Olympic ST, SPRINGFIELD, OR 97477 (Rooftop)
  2. 2524 Olympic ST, SPRINGFIELD, OR 97477 (Interpolated)
