摘要

PROBLEM TO BE SOLVED: To provide an apparatus and method for associating links in different road network data mutually.;SOLUTION: A road network data association apparatus includes: a first storage part that stores first road network data (first data); and a second storage part that stores second road network data (second data) different from the first data. A road network data association method for associating a link in the first data with a link in the second data includes: extracting a link satisfying a first condition, as a reference of comparison in the first data and a link to be compared in the second data; comparing an element of the extracted reference link with an element of the link to be compared; adjusting the link to be compared to generate a virtual link when a result of comparison corresponds to a second condition; and associating the reference link with the generated virtual link.;COPYRIGHT: (C)2014,JPO&INPIT
