Radius / Corridor Samples

Radius and Corridor samples offer a more specialized approach and are geometric in nature.

 

Radius samples

 

The radius sampling method provides a sample of listed phone records, randomly selected from Postal Codes or Zip Codes whose centroids are located within a specified distance from any geographic target coordinates in the US or Canada.

 

 

 

Corridor Samples

 

The corridor sampling method provides a sample of listed phone records, randomly selected from Postal Codes or Zip Codes whose centroids are located within a specified distance from a line on a map. The target coordinates define the extremity of the line or corridor. This can be a road or section of a road represented by two sets of coordinates.
