Address Point Interpolation

Address point interpolation is a patented process that results in a more accurate interpolated point. It improves upon regular street segment interpolation by using point data in the interpolation process, as opposed to using street segments alone.

Note: Address point interpolation requires both a street-level and a point-level geocoding dataset.

Note: For USA, this feature is not supported with point addresses in Auxiliary files.

The following illustration shows how address point interpolation works. In the example, the input house number is 71. The geocoding dataset contains address points for 67 and 77. The street segment has a range of 11 to 501. With address point interpolation, the Global Geocoding REST API performs the interpolation for the input house number 71 using the points of 67 and 77. Without address point interpolation, the Global Geocoding REST API performs the interpolation with the street segment end points of 11 and 501, resulting in a far less accurate result.

Note: This feature is only supported for the following countries:

The following table provides information on how to implement address point interpolation.
