    Driving Distances and Times Using SAS and Google Maps

    SAS 9.2 contains new functions (ZIPCITYDISTANCE, GEODIST) that allow a user to compute geodesic distance (the shortest distance between two points on the surface of a sphere). Both functions use the Vincenty distance formula. Prior to SAS 9.2, a data step was used to compute such distances, commonly with the...
