NAACCR Shortest Path Finder Tool

What is it?

The NAACCR Shortest Path Finder Tool is a web-based software application for the processing of research data sets to allow time and distance comparisons of routes utilizing road networks.

What does it do?

The tool takes user input (normally in the form of a database or spreadsheet) with start and end coordinates and generates the time and distance to travel from start to finish using the United States or Canadian road network. In this way, it is similar to generating driving directions using Google Maps® or MapQuest® with the following exceptions:

  • The only data returned are the time, distance, and optional KML output.
  • The input data must contain geographic coordinates as opposed to (or in addition to) street addresses.

What does it not do?

The tool does not:

  • Display the results of a road network path in any visual format, although the optional KML output can be used in Google Earth® to display the generated route on a map.
  • Use addresses for start and end points or translate addresses into geographic coordinates. The input data must contain fully geocoded data (coordinates) to run.

How it can be used?

The NAACCR Shortest Path Finder Tool can be used to analyze geographic data sets for patterns in travel time and/or distance. One such paper has already been released by the Geographic Information Systems Committee of NAACCR and several more are in the works.
